is exposed to light.
• Best charging performance is
achieved by exposing the watch to
the strongest light available.
E-83 Troubleshooting
E-87 Specifications
When wearing the watch, make sure
that its face is not blocked from light
by the sleeve of your clothing.
• The watch may enter a sleep state
(page E-14) if its face is blocked
by your sleeve even only partially.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become particularly hot
when exposed to the following conditions for long periods.
• On the dashboard of a car parked in direct sunlight
• Too close to an incandescent lamp
• Under direct sunlight
E-8
E-9
Important!
• Allowing the watch to become very hot can cause its liquid crystal display to black out. The
appearance of the LCD should become normal again when the watch returns to a lower temperature.
• Turn on the watch’s Power Saving function (page E-14) and keep it in an area normally exposed to
bright light when storing it for long periods. This helps to ensure that power does not run down.
• Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is
blocked from exposure to light can cause power to run down. Expose the watch to bright light
whenever possible.
Power Levels
You can check the current battery power level by viewing the battery power indicator that appears on the
digital display when you enter the Timekeeping Mode.
• To enter the Timekeeping Mode from any other mode, hold down D for about two seconds.

• The flashing L indicator at Level 3 tells you that battery power is very low, and that exposure to bright
light for charging is required as soon as possible.
• At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery
reaches Level 2 (M) after falling to Level 5, reconfigure the current time, date, and other settings.
• Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (M).
• Leaving the watch exposed to direct sunlight or some other very strong light source can cause the
battery power indicator to show a reading temporarily that is higher than the actual battery level. The
correct battery level should be indicated after a few minutes.
• All data stored in memory is deleted, and the current time and all other settings return to their initial
factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.
• Battery power takes about 15 minutes to recover. The recovery indicator (R) will stop flashing and
normal watch operation will be restored when battery recovery is complete.
• Frequent flashing of the recovery indicator (R) indicates that battery power is low. Expose the watch to
light to charge its battery.

Interpreting Direction Reading Results
• When you press C, COMP appears on the digital display to indicate that direction reading has started.
• After about two seconds, the second hand moves to point to magnetic north. The digital display shows
either the angle between magnetic north and the 12 o’clock position of the watch, or one of 16 literal
direction indicators.
• The watch updates the direction reading about once every second for about 20 seconds, and then
stops. The digital display shows - - - and the second hand moves to COMP (located below the C
button) to indicate that direction readings are complete. If your want to continue taking direction
readings, press C again.
• Pressing E at this time switches the digital display between the angle value and a one-, two-, or
three-character literal direction indicators.
• The Auto Light switch is disabled during the 20 seconds that direction readings are being taken.
• The following table shows the meanings of the abbreviations used for the literal direction indicators that
appear on the digital display.

• The margin of error for the angle value and the direction indicator is ±11 degrees while the watch is
horizontal (in relation to the horizon). If the indicated direction is northwest (NW) and 315 degrees, for
example, the actual direction can be anywhere from 304 to 326 degrees.
• If the second hand is indicating 12 o’clock (north), the digital display will show an upwards pointing
white on black arrow.
• The small scale in the center of the watch face is a direction scale (page E-25). You can use the
direction scale to get an idea of how many degrees the 12 o’clock position of the watch is (clockwise)
from the northerly indication of the second hand. The direction scale is marked in 10-degree increments.
Some watch models may not have a direction scale.
• Note that taking a measurement while the watch is not horizontal (in relation to the horizon) can result in
large measurement error.
• You can calibrate the bearing sensor if you suspect the direction reading is incorrect.
• Any ongoing direction measurement operation is paused temporarily while the watch is performing an
alert operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned
on (by pressing L). The measurement operation resumes for its remaining duration after the operation
that caused it to pause is finished.
• For precautions that should be observed when using the Compass Mode, see “Compass Precautions”
(page E-34).
Calibrating the Bearing Sensor
You should calibrate the bearing sensor whenever you feel that the direction readings being produced by
the watch are off. There are three different calibration methods available: magnetic declination correction,
bidirectional calibration, and northerly calibration.
• Magnetic Declination Correction
With magnetic declination correction, you input a magnetic declination angle (difference between
magnetic north and true north), which allows the watch to indicate true north. You can perform this
procedure when the magnetic declination angle is indicated on the map you are using. Note that you can
input the declination angle in whole degree units only, so you may need to round off the value specified
on the map. If your map indicates the declination angle as 7.4°, you should input 7°. In the case of 7.6°
input 8°, for 7.5° you can input 7° or 8°.
E-26
E-27
• Bidirectional Calibration and Northerly Calibration
Bidirectional calibration and northerly calibration calibrate the accuracy of the bearing sensor in relation
to magnetic north. Use bidirectional calibration when you want to take readings within an area exposed
to magnetic force. This type of calibration should be used if the watch becomes magnetized for any
reason. With northerly calibration, you “teach” the watch which way is north (which you have to determine
with another compass or some other means).
Important!
The more correctly you perform bidirectional calibration, the better the accuracy of the bearing sensor
readouts. You should perform bidirectional calibration whenever you change environments where you
use the bearing sensor, and whenever you feel that the bearing sensor is producing incorrect readings.
To perform magnetic declination correction
1. In the Compass Mode, hold down E until each of the following steps
Magnetic declination
occurs.

2. Use A (East) and C (West) to change the settings.
• The following explains magnetic declination angle direction settings.

No magnetic declination correction performed. The magnetic
declination angle with this setting is 0°.
E:
When magnetic north is to the east (east declination)
W:
When magnetic north is to the west (west declination)
• You can select a value within the range of W 90 ° to E 90 ° with these
settings.
• To return the magnetic declination to its initial factory default setting, press A and C at the same
time. This will cause OFF to appear on the digital display. After about one second, the magnetic
declination will change to 0 degrees.
• The illustration on page E-28 shows declination angle direction value and the angle value you should
select when a map shows a magnetic declination of “West 1°”.
3. When the setting is the way you want, press E to exit the setting screen.
Precautions about bidirectional calibration
• You can use any two opposing directions for bidirectional calibration. You must, however, make sure
that they are 180 degrees opposite each other. Remember that if you perform the procedure
incorrectly, you will get wrong bearing sensor readings.
• Do not move the watch while calibration of either direction is in progress.
• You should perform bidirectional calibration in an environment that is the same as that where you plan
to be taking direction readings. If you plan to take direction readings in an open field, for example,
calibrate in an open field.
To perform bidirectional calibration
1. In the Compass Mode, hold down E until each of the following steps
occurs.
• Hold SET appears on the digital display. ➝ Magnetic declination
settings flash.
• This is the setting screen.
2. Press D to display the bidirectional calibration screen.
• At this time, the digital display will show -1- to indicate that the watch
is ready to calibrate the first direction.
E-28
E-29
3. Place the watch on a level surface facing any direction you want, and press C to calibrate the first
direction.
• - - - is shown on the digital display while calibration is being performed. When calibration is
successful, the digital display will show -2-. This means that the watch is ready for calibration of
the second direction.
• Calibration takes about 13 seconds. Do not move the watch while calibration is being performed.
4. Rotate the watch 180 degrees.
5. Press C again to calibrate the second direction.
• - - - is shown on the digital display while calibration is being performed. When calibration is
successful, the digital display will show OK and then change to the Compass Mode screen (- - -).
To perform northerly calibration
Important!
If you want to perform both northerly and bidirectional calibration, perform bidirectional calibration first,
and then perform northerly calibration. This is necessary because bidirectional calibration cancels any
existing northerly calibration setting.
1. In the Compass Mode, hold down E until each of the following steps
occurs.
• Hold SET appears on the digital display. ➝ Magnetic declination
settings flash.
• This is the setting screen.
4. Press C to start the calibration operation.
• - - - is shown on the digital display while calibration is being performed. When calibration is
successful, the digital display will show OK and then change to the Compass Mode screen (- - -).
Using the Compass While Mountain Climbing or Hiking
This section provides two practical applications for using the watch’s built-in compass.
• Setting a map and finding your current location
Having an idea of your current location is important when mountain climbing or hiking. To do this, you
need to “set the map”, which means to align the map so the directions indicated on it are aligned with
the actual directions of your location. Basically what you are doing is aligning north on the map with
north as indicated by the watch.
• Finding the bearing to an objective
To set a map and find your current location
1. With the watch on your wrist, position it so the face is horizontal.
2. While in the Timekeeping Mode or in any of the sensor modes, press C to take a compass reading.
• The reading result will appear on the digital display after about two seconds, and the second hand
will point to north.
2. Press D twice to display the northerly calibration screen.
• At this time, -n- (north) appears on the digital display.
3. Place the watch on a level surface, and position it so that its 12 o’clock position points north (as
measured with another compass).

3. Rotate the map without moving the watch so the northerly direction
indicated on the map matches north as indicated by the watch.
• If the watch is configured to indicate magnetic north, align the
map’s magnetic north with the watch indication. If the watch has
been configured with a declination to correct to true north, align
the map’s true north with the watch indication. For details about
magnetic declination correction, see “Calibrating the Bearing
Sensor” (page E-27).
• This will position the map in accordance with your current location.
To find the bearing to an objective
1. Set the map so its northerly indication is aligned with north as indicated
by the watch, and determine your current location.
• See “To set a map and find your current location” on page E-31 for
N
information about how to perform the above step.

Compass Precautions
This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that
north indicated by this watch is magnetic north, which is somewhat different from true polar north. The
magnetic north pole is located in northern Canada, while the magnetic South Pole is in southern Australia.
Note that the difference between magnetic north and true north as measured with all magnetic compasses
tends to be greater as one gets closer to either of the magnetic poles. You should also remember that
some maps indicate true north (instead of magnetic north), and so you should make allowances when
using such maps with this watch.
Location
• Taking a direction reading when you are near a source of strong magnetism can cause large errors in
readings. Because of this, you should avoid taking direction readings while in the vicinity of the
following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal
(metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal
computers, washing machines, freezers, etc.).
• Accurate direction readings are impossible while in a train, boat, air plane, etc.
• Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is
because the metal framework of such structures picks up magnetism from appliances, etc.
Storage
• The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of
this, you should store the watch away from magnets or any other sources of strong magnetism,
including: permanent magnets (magnetic necklaces, etc.) and household appliances (TVs, personal
computers, washing machines, freezers, etc.).
• Whenever you suspect that the watch may have become magnetized, perform the procedure under “To
perform bidirectional calibration” (page E-29).
Taking Barometric Pressure and Temperature Readings
This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature
sensor to measure temperature.

• Barometric pressure is displayed in units of 1 hPa (or 0.05 inHg).
• The displayed barometric pressure value changes to - - - if a measured barometric pressure falls outside
the range of 260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg). The barometric pressure value will reappear
as soon as the measured barometric pressure is within the allowable range.
Reading the Barometric Pressure Graph
Temperature
• Temperature is displayed in units of 0.1°C (or 0.2°F).
• The displayed temperature value changes to - - - °C (or °F) if a measured temperature falls outside the
range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The temperature value will reappear as soon as the
measured temperature is within the allowable range.
Display Units
You can select either hectopascals (hPa) or inchesHg (inHg) as the display unit for the measured
barometric pressure, and Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature
value. See “To specify temperature, barometric pressure, and altitude units” (page E-60).
Barometric
pressure graph
Barometric pressure indicates changes in the atmosphere. By monitoring
these changes you can predict the weather with reasonable accuracy.
This watch takes barometric pressure measurements automatically every
two hours (at the 30th minute of every even numbered hour).
Measurement results are used as the data to create the barometric
pressure graph that appears on the digital display, and the second hand
indicates the barometric pressure differential.
The barometric pressure graph shows readings of previous measurements for up to 16 hours.
Barometric
pressure
Time
• The horizontal axis of the graph represents time, with each dot
standing for two hours. The rightmost dot represents the most recent
reading.
• The vertical axis of the graph represents barometric pressure, with
each dot standing for the relative difference between its reading and
that of the dots next to it. Each dot represents 1 hPa.
The following shows how to interpret the data that appears on the barometric pressure graph.
A rising graph generally means improving weather.
A falling graph generally means deteriorating weather.

Pressure Sensor and Temperature Sensor Calibration
The pressure sensor and temperature sensor built into the watch are calibrated at the factory and normally
require no further adjustment. If you notice serious errors in the pressure readings and temperature
readings produced by the watch, you can calibrate a sensor to the reading of another device to correct the
errors.
To calibrate the pressure sensor and the temperature sensor
1. Take a reading with another measurement device to determine the
exact current barometric pressure or temperature.
2. With the watch in the Timekeeping Mode or in any of the sensor
modes, press B to enter the Barometer/Thermometer Mode.
3. Hold down E until each of the following steps occurs.
• Hold SET appears on the digital display. ➝ The current temperature
value flashes.
Important!
• Incorrectly calibrating the pressure sensor can result in incorrect readings. Before changing the
calibration value, make sure the readings you are using are reliable and accurate.
• Incorrectly calibrating the temperature sensor can result in incorrect readings.
Carefully read the following before doing anything.
– Compare the readings produced by the watch with those of another reliable and accurate thermometer.
– If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the
temperature of the watch time to stabilize.
Press D.
4. Press D to move the flashing between the temperature value and
barometric pressure value, to select the one you want to calibrate.
5. Use A (+) and C (–) to adjust the calibration value in the units shown
below.

Barometer and Thermometer Precautions
• The pressure sensor built into this watch measures changes in air pressure, which you can then apply
to your own weather predictions. It is not intended for use as a precision instrument in official weather
prediction or reporting applications.
• Sudden temperature changes can affect pressure sensor readings.
• Temperature measurements are affected by your body temperature (while you are wearing the watch),
direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the
watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture
from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual
surrounding temperature.
Taking Altitude Readings
The watch displays altitude values based on air pressure readings taken by a built-in pressure sensor.
How the Altimeter Measures Altitude
The altimeter can measure altitude based on its own preset values (initial default method) or using a
reference altitude specified by you.
When you measure altitude based on preset values
Data produced by the watch’s barometric pressure sensor is converted to approximate altitude based on
ISA (International Standard Atmosphere) conversion values stored in watch memory.
When you measure altitude using a reference altitude specified by you
After you specify a reference altitude, the watch uses that value to convert
barometric pressure readings to altitude (page E-53).
• When mountain climbing, you can specify a reference altitude value in
accordance with a marker along the way or altitude information from a
map. After that, the altitude readings produced by the watch will be more
accurate than they would without a reference altitude value.

1. Make sure the watch is in the Timekeeping Mode or any one of the
sensor modes.
• The sensor modes are: Compass Mode, Barometer/Thermometer
Mode, and Altimeter Mode.
2. Press A to start Altimeter measurement.
• When you press A, the second hand will first point in the direction of
the A (ALTI) button. This indicates the Altimeter Mode. After that,
the second hand will point at the current altitude differential.
• ALTI will appear on the digital display, indicating that Altimeter
measurement is in progress. The first reading will appear on the
digital display after about four or fi ve seconds.
• The current altitude value is displayed in units of 5 meters (20 feet).
• After the first reading is obtained, the watch continues to take
altimeter readings automatically every fi ve seconds for the first
three minutes, and then every two minutes after that (under initial
default settings).
• If you leave the watch in the Altimeter Mode, it will update the displayed altitude value regularly and
indicate reading-to-reading changes in graph form.
• You can use the procedure under “Selecting an Altitude Auto Measurement Method” (page E-46) to
specify the altitude auto measurement method you want to use.
The altitude graph shows Altimeter Mode auto measurement readings over time.

Altitude
Time
• The vertical axis of the graph represents altitude, and each dot stands
for 10 meters (40 feet).
• The horizontal axis represents time. For the altitude readings taken
during the first three minutes after you start an altimeter measurement
operation, each dot represents five seconds. After that, each dot
represents two minutes (under initial default settings).
• An out of range reading or a measurement error will cause the column
of dots for that reading to be blank (skipped).
Note
• The measurement range for altitude is –700 to 10,000 meters (–2,300 to 32,800 feet).
• The displayed altitude value changes to - - - - if an altitude reading falls outside the measurement
range. An altitude value will reappear as soon as the altitude reading is within the allowable range.
• Normally, displayed altitude values are based on the watch’s preset conversion values. You also can
specify a reference altitude value, if you want. See “Specifying a Reference Altitude Value” (page E-52).
• You can change the unit for displayed altitude values to either meters (m) or feet (ft). See “To specify
temperature, barometric pressure, and altitude units” (page E-60).
3. After you are finished using the Altimeter, press D to return to the Timekeeping Mode and stop auto
measurement.
• The watch will return to the Timekeeping Mode automatically if you do not perform any operation for
about 10 hours after entering the Altimeter Mode (under initial default settings).

Selecting an Altitude Auto Measurement Method
You can select either of the following two altitude auto measurement methods.
0’05 1H: Readings at five-second intervals for one hour
2’00 10H: Readings at five-second intervals for the first three minutes followed by two-minute
intervals for approximately 10 hours
Note
If you do not perform any button operation while in the Altimeter Mode, the watch will return to the
Timekeeping Mode automatically after 10 hours (altitude auto measurement method: 2’00 10H) or after
one hour (altitude auto measurement method: 0’05 1H).
To select the altitude auto measurement method
1. In the Altimeter Mode, hold down E until each of the following steps
occurs.
• Hold SET appears on the digital display. ➝ Hold SET disappears.
2. Press D to display the current altitude auto measurement method
setting.
• This will cause either 0’05 or 2’00 to flash on the digital display.
3. Press A to toggle the altitude auto measurement method setting
between 0’05 1H and 2’00 10H.
Using the Altitude Differential Value
Altitude differential
indicated by second hand
In the Altimeter Mode, the part of the watch’s dial from 11 o’clock to 7
o’clock acts as an altitude differential scale. The second hand points to a
place on the scale that indicates the difference between the altitude at a
start point set by you and the altitude at your current location. The altitude
differential indication is updated each time the watch takes an altitude
reading.
You can configure the watch so each second mark in the altitude
differential scale stands for 5 meters (20 feet) or 50 meters (200 feet).
See “Configuring the Altitude Differential Scale” (page E-49) for
information about how to configure this setting.
• The second hand will point to OVER or UNDER if the altitude
differential is outside the allowable range of the scale.
• The second hand will move to 9 o’clock if a sensor reading could not
be taken for some reason or if the reading is outside the allowable
range.
• See “Using the Altitude Differential Value While Mountain Climbing or
Hiking” (page E-51) for some real-life examples of how to use this

altitude
take an altimeter reading” (page E-44) for details.
4. Press E to exit the setting screen.
To set the altitude differential start point
In the Altimeter Mode, press E.
• The watch will take an altitude reading and record the result as the
current differential start point. At this time, the second hand will point
to 0 because that is the current altitude differential.
2. Use the contour lines on your map to determine the difference in
altitude between your current location and your destination.
3. In the Altimeter Mode, press E to specify your current location as the
altitude differential start point.
• The watch will take an altitude reading and register the result as
the altitude differential value start point. The altitude differential
value will be reset to zero at this time.

destination.
• If the map shows a difference of +80 meters between your current
location and your destination, you will know that you are
approaching your destination when the second hand is pointed
at +80 meters.
To specify a reference altitude value
1. In the Altimeter Mode, hold down E until each of the following steps
occurs.
• Hold SET appears on the digital display. ➝ Hold SET disappears.
2. Press A (+) or C (–) to change the current reference altitude value
by 5 meters (or 20 feet).
• Specify a reference altitude value based on accurate altitude
information about your current location from a map, etc.
• You can set the reference altitude value within the range of –10,000
to 10,000 meters (–32,800 to 32,800 feet).
• Pressing A and C at the same time returns to OFF (no reference
altitude value), so the watch performs air pressure to altitude
conversions based on preset data only.
Altitude
3. Press E to exit the setting screen.
Specifying a Reference Altitude Value
The altitude readings produced by this watch are subject to error caused by changes in air pressure.
Because of this, we recommend that you update the reference altitude value whenever one is available
during your climb. After you specify a reference altitude value, the watch adjusts its air-pressure-to-altitude
conversion calculation accordingly.
Types of Altitude Data
The watch maintains two types of altitude data in its memory: manual save records and auto save values
(low altitude, high altitude, cumulative ascent, cumulate descent).
• Use the Data Recall Mode to view data stored in memory. See “Viewing Altitude Records” (page E-63)
for details.
E-52
E-53
Manual Save Records
Auto Save Values
Any time you perform the procedure below in the Altimeter Mode, the watch will create and store a record
with the currently displayed altitude reading, along with the date and time the reading was taken. There is
enough memory to store up to 14 manual save records, which are numbered from REC01 through
REC14.
While the altitude auto measurement method is being used (page E-46), the watch automatically stores
high altitude (HI), low altitude (LO), cumulative ascent (ASC), and cumulative descent (DSC) values.
• These values are checked and updated automatically by the watch as altitude auto measurements are
taken.
To create a manual save record
1. In the Altimeter Mode, check to make sure that an altitude reading is
on the digital display.
• If an altitude reading is not displayed, press A to take one. See “To
take an altimeter reading” (page E-44) for details.
How the high altitude and low altitude values are updated
While the watch is in the Altimeter Mode, altitude readings are taken automatically at the interval specified
by the altitude auto measurement method (page E-46). With each reading, the watch compares the
current reading against the HI and LO values. It will replace the HI value if the current reading is greater
than HI, or the LO value if the current reading is less than LO.
2. Hold down A until Hold REC appears on the digital display and then
changes to REC.
• This will save the currently displayed altitude reading in a manual
save record, along with the measurement time and date.
• The watch will return to the Altimeter Mode screen automatically after
the save operation is complete.
• There is enough memory to store up to 14 manual save records. If
there are already 14 manual save records in memory, the above
operation will cause the oldest record to be deleted automatically
to make room for the new one.

The total Cumulative Ascent and Cumulative Descent values produced by an Altimeter Mode
measurement session during the example climb illustrated above are calculated as follows.
Cumulative Ascent: q (300 m) + e (620 m) = 920 m
Cumulative Descent: w (320 m) + r (500 m) = 820 m
• Entering the Altimeter Mode starts a new altitude auto measurement session, but it does not reset the
current ASC and DSC values or change them in any way. This means that the starting ASC and DSC
values for a new Altimeter Mode auto measurement session are the values that currently are in memory.
Each time you complete an Altimeter Mode auto measurement session by returning to the Timekeeping
Mode, the cumulative ascent value of the current session (920 meters in the above example) is added
to the session’s starting ASC value. Also, the cumulative descent value of the current auto
measurement session (–820 meters in the above example) is added to the session’s starting DSC
value.
• Note that any change in elevation when ascending that is less than 15 meters (49 feet) is not added to
the cumulative ascent value for the current Altimeter Mode auto measurement session. Also, any
change in elevation when descending that is less than –15 meters (–49 feet) is not added to the
cumulative descent value for the current Altimeter Mode auto measurement session.
How does the altimeter work?
Generally, air pressure and temperature decrease as altitude increases. This watch bases its altitude
measurements on International Standard Atmosphere (ISA) values stipulated by the International Civil
Aviation Organization (ICAO). These values define relationships between altitude, air pressure, and
temperature.

Altimeter Precautions
• This watch estimates altitude based on air pressure. This means that altitude readings for the same
location may vary if air pressure changes.
• The semiconductor pressure sensor used by the watch for altitude measurements is also affected by
temperature. When taking altitude measurements, do not subject the watch to temperature changes.
• Do not rely upon this watch for altitude measurements or perform button operations while sky diving,
hang gliding, or paragliding, while riding a gyrocopter, glider, or any other aircraft, or while engaging in
any other activity where there is the chance of sudden altitude changes.
• Do not use this watch for measuring altitude in applications that demand professional or industrial level
precision.
• Remember that the air inside of a commercial aircraft is pressurized. Because of this, the readings
produced by this watch will not match the altitude readings announced or indicated the flight crew.

Precautions Concerning Simultaneous Measurement of Altitude and Temperature
Viewing Altitude Records
Though you can perform altitude and temperature measurements at the same time, you should remember
that each of these measurements requires different conditions for best results. With temperature
measurement, it is best to remove the watch from your wrist in order to eliminate the effects of body heat.
In the case of altitude measurement, on the other hand, it is better to leave the watch on your wrist,
because doing so keeps the watch at a constant temperature, which contributes to more accurate altitude
measurements.
• To give altitude measurement priority, leave the watch on your wrist or in any other location where the
temperature of the watch is kept constant.
• To give temperature measurement priority, remove the watch from your wrist and allow it to hang freely
from your bag or in another location where it is not exposed to direct sunlight. Note that removing the
watch from your wrist can affect pressure sensor readings momentarily.
Use the Data Recall Mode to view manual save altitude records and automatically saved high altitude, low
altitude, cumulative ascent, and cumulative descent values. Altitude records are created and saved in the
Altimeter Mode.
To view altitude records
1. Use D to select the Data Recall Mode (REC) as shown on page E-16.

2. Use A and C to scroll through altitude records in the sequence
shown on page E-64.
• For a manual save record, high altitude and low altitude records, the
month and day of the reading will appear first. After about one
second, this will change to show the time of the reading. After that
the time and altitude reading will alternate on the digital display
at one-second intervals. For cumulative ascent and cumulative
descent, the digital display will show the month and day of the
first reading. After about one second, this will change to show the
cumulative altitude.

40°
Warning!
• Always make sure you are in a safe place whenever you are reading the display of the watch
using the auto light switch. Be especially careful when running or engaged in any other activity
that can result in accident or injury. Also take care that sudden illumination by the auto light
switch does not startle or distract others around you.
• When you are wearing the watch, make sure that its auto light switch is turned off before riding
on a bicycle or operating a motorcycle or any other motor vehicle. Sudden, unintended operation
of the auto light switch can create a distraction, which can result in a traffic accident and serious
personal injury.
Note
• This watch features a “Full Auto LED Light”, so the auto light switch operates only when available light
is below a certain level. Illumination does not turn on under bright light.
• The auto light switch is always disabled, regardless of its on/off setting, when any one of the following
conditions exists.
While an alarm is sounding
During sensor measurement
While a bearing sensor calibration operation is being performed in the Compass Mode
While a hand home position adjustment operation is in progress
Wear the watch on the
outside of your wrist
E-79
Operation Guide 5113 5213
To turn the auto light switch on and off
1. In the Timekeeping Mode, hold down E until each of the following
steps occurs.
• Hold SET appears on the digital display. ➝ HT flashes. ➝ Second
hand points to the current Home City code.
2. Use D to cycle through the settings on the digital display until the
current auto light switch setting (AT OFF or AT On) is flashing on the
digital display.
• See step 3 under “To change the current time and date settings” (page
E-22) for information about how to scroll through setting screens.
Auto light switch precautions
• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can
cause frequent activation of the auto light switch and illumination. To avoid running down the battery,
turn off the auto light switch whenever engaging in activities that might cause frequent illumination.
• Note that wearing the watch under your sleeve while the auto light switch is turned on can cause
frequent illumination and can run down the battery.
• Illumination may not turn on if the face of the watch is more than 15 degrees above
or below parallel. Make sure that the back of your hand is parallel to the ground.
• Illumination turns off after the preset illumination duration (page E-78), even if you
keep the watch pointed towards your face.
• Static electricity or magnetic force can interfere with proper operation of the auto
light switch. If illumination does not turn on, try moving the watch back to the
starting position (parallel with the ground) and then tilt it back towards your face
again. If this does not work, drop your arm all the way down so it hangs at your
side, and then bring it back up again.
• You may notice a very faint clicking sound coming from the watch when it is shaken
back and forth. This sound is caused by mechanical operation of the auto light
switch, and does not indicate a problem with the watch.
3. Press A to toggle the auto light switch setting between on (On) or off
(OFF).
4. After the setting is the way you want, press E to exit the setting screen.
Illumination Precautions
• Frequent use of illumination can run down the battery, which will require exposing the watch to light for
charging.
The following guidelines give an idea of the charging time required to recover from a single illumination
operation.
Approximately five minutes exposure to bright sunlight coming in through a window
Approximately 50 minutes exposure to indoor fluorescent lighting
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.

Hand Home Position Adjustment
■ The time indicated by the hands is different from the time shown on the digital display
If the displayed time and the time indicated by the hands do not match, it could mean that the hand home
positions are off. Use the Hand Home Position Adjustment Mode (page E-76) to adjust them.
Sensor modes
■ I can’t change the temperature, barometric pressure, and altitude units.
When TOKYO (TYO) is selected as the Home City, the altitude unit is set automatically to meters (m), the
barometric pressure unit to hectopascals (hPa), and the temperature unit to Celsius (°C). These settings
cannot be changed.
■ “Err” appears on the digital display while I am using a sensor.
Subjecting the watch to strong impact can cause sensor malfunction or improper contact of internal
circuitry. When this happens, Err (error) will appear on the digital display and sensor operations will be
disabled.

• If Err appears while a measurement operation is being performed in a sensor mode, restart the measurement.
If Err appears on the digital display again, it can mean there is something wrong with the sensor.
• Even if battery power is at Level 1 (H) or Level 2 (M), the Compass Mode, Barometer/Thermometer
Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it
sufficiently. In this case, Err will appear on the digital display. This does not indicate malfunction, and
sensor operation should resume once battery voltage returns to its normal level.
• If Err keeps appearing during measurement, it could mean there is a problem with the applicable
sensor.
■ “Err” appears on the digital display after I perform bidirectional calibration or northerly
calibration.
If - - - appears and then changes to Err (error) on the calibration screen, it means that there is something
wrong with the sensor.
• If Err disappears after about one second, try performing the calibration again.
• If Err keeps appearing, contact your original dealer or nearest authorized CASIO distributor to have the
watch checked.
■ “Err” appears on the digital display after I perform northerly calibration.
The Err message indicates there may be some problem with the sensor. The Err message also may be
due to movement of the watch while the calibration procedure is being performed. Try performing
calibration again, taking care to ensure that the watch is not moved.
If this does not solve the problem, the problem may be due to some nearby source of terrestrial
magnetism. Try performing the calibration procedure again from the beginning.
Whenever you have a sensor malfunction, take the watch to your original dealer or nearest authorized
CASIO distributor as soon as possible.
■ What causes incorrect direction readings?
• Incorrect bidirectional calibration. Perform bidirectional calibration (page E-29).
• Nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel
beam, overhead wires, etc., or an attempt to perform direction measurement on a train, boat, etc. Move
away from large metal objects and try again. Note that compass operation cannot be performed inside
a train, boat, etc.
■ What causes different direction readings to produce different results at the same location?
Magnetism generated by nearby high-tension wires is interfering with detection of terrestrial magnetism.
Move away from the high-tension wires and try again.
■ Why am I having problems taking direction readings indoors?
A TV, personal computer, speakers, or some other object is interfering with terrestrial magnetism
readings. Move away from the object causing the interference or take the direction reading outdoors.
Indoor direction readings are particularly difficult inside ferro-concrete structures. Remember that you will
not be able to take direction readings inside of trains, airplanes, etc.
E-84
■ Why doesn’t the second hand indicate the barometric pressure differential when I enter the
Barometer/Thermometer Mode?
• This could indicate sensor error. Try pressing B again.
• The barometric pressure differential is not indicated by the second hand if the pressure reading is
outside the allowable measurement range (260 to 1,100 hPa).
World Time Mode
■ The time for my World Time City is off in the World Time Mode.
This could be due to incorrect switching between standard time and daylight saving time. See “To specify
standard time or daylight saving time (DST) for a city” (page E-74) for more information.
Charging
■ The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 5 (page E-11). Continue exposing the watch to light
until the battery power indicator shows “H” or “M”.
