Congratulations upon your selection of this CASIO watch.
x Note that the product illustrations in this manual are intended for reference only, and
so the actual product may appear somewhat different than depicted by an illustration.
This watch does not have a city code that corresponds to the UTC offset of –3.5
hours. Because of this, the radio-controlled atomic timekeeping function will not
display the correct time for Newfoundland, Canada.
E-1
Warning!
x The measurement functions built into this watch are not intended for taking

To stop high-speed movement
High-speed Movement
When rotating the crown to move the hands of the watch, you can use the operations
described below to move the hands at high speed, either forward or back. There are
two high-speed levels: HS1 and HS2 (faster than HS1).
To start HS1 high-speed movement
While the crown is pulled out, rotate it rapidly three turns away
from you (for forward movement) or towards you (for reverse
movement). High-speed movement will continue even if you
release the crown.
To start HS2 high-speed movement
While HS1 high-speed movement is in progress, again rotate
the crown rapidly three turns in the same direction as the
current HS1 movement (away from you for forward movement
or towards you for reverse movement).
Rotate the crown in the direction that is opposite that of the
current high-speed movement or press any button.
Note
x If you do not perform any operation for more than two minutes after pulling out the
crown, crown operations will become disabled automatically. If this happens, push
the crown back in and then pull it out again to re-enable crown operations.
x You can use high-speed hand movement when configuring time settings in the
Timekeeping Mode, Alarm Mode, or Countdown Timer Mode.
x Button operations become disabled after you perform a crown operation. If this
happens, rotate the crown slightly. This should restore button operations.

Charging the Watch
The face of the watch is a solar panel that generates power from light. The generated
power charges a built-in rechargeable battery, which powers watch operations. The
watch charges whenever it is exposed to light.
Charging Guide
Whenever you are not
wearing the watch, be sure
to leave it in a location
where it is exposed to light.
x Best charging
performance is achieved
by exposing the watch to
light that is as strong as
possible.
When wearing the watch,
makes sure that its face is
not blocked from light by
the sleeve of your clothing.
x The watch may enter a
sleep state (page E-19) 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.
x On the dashboard of a car parked in direct sunlight
x Too close to an incandescent lamp
x Under direct sunlight
Important!
x Keep the watch in an area normally exposed to bright light when storing it for long
periods. This helps to ensure that power does not run down.
x 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.
Make sure that the watch is exposed to bright light whenever possible.
Checking the Current Power Level
Certain functions will be disabled when the power level is low. If the power level is
low, leave the watch in a location where its face (solar panel) is exposed to light.
E-14
E-15
Low Power
@
Low power conditions are indicated by the movement of
the x Second Hand in the Timekeeping Mode.
x If the x Second Hand is moving normally at one-second
intervals, power is at Level 1.
x If the x Second Hand is moving at two-second intervals,
power is at Level 2, which is quite low. Expose the watch
to light as soon as possible so it can charge.

x When power drops to Level 3, all settings (including timekeeping) will be cleared.
Recharging the battery will reset all settings to their initial factory defaults.
x When the watch is at Level 3, exposing it to light for a while will cause the x Second
Hand to move to the position of second 57. This indicates that charging has started.
Power Recovery Mode
The watch is designed to go into a power recovery mode that stops hand operation
temporarily whenever power suddenly drops below a certain level due to continuous
signal reception or other operations over a short period. Note that all operations are
disabled while the watch is in the power recovery mode.
The hands will move to the correct positions and the watch will resume normal
operation after power recovers (in about 15 minutes). Putting the watch in a location
where it is exposed to light will help power to recover sooner.

Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
However, when using the watch outside of areas covered by time calibration signals,
you will have to adjust the settings manually as required. See “Configuring Current
Time and Day Settings Manually” (page E-41) for more information.
This section explains how the watch updates its time settings when the city code
selected as the Home City is in Japan, North America, Europe, or China, and is one
that supports time calibration signal reception.
If your Home City Code setting is this:
The watch can receive the signal from
the transmitter located here:
LON (LONDON), PAR (PARIS), ATH (ATHENS)
Anthorn (England), Mainflingen
(Germany)
HKG (HONG KONG)
Shangqiu City (China)
TYO (TOKYO)
Fukushima (Japan), Fukuoka/Saga
(Japan)
HNL (HONOLULU), ANC (ANCHORAGE),
LAX (LOS ANGELES), DEN (DENVER), CHI
(CHICAGO), NYC (NEW YORK)

STD/DST Switching
You can select summer time or standard time independently for each city. The initial
default setting for all cities is AT (AUTO).
Normally you should use the AT (AUTO) setting because it automatically switches
between summer time and standard time. You should change the setting to STD
(standard time) or DST (summer time) in the following cases.
− When using a time of a location that is not included in the watch’s list of 29 cities
− When the preset AUTO standard time/summer time timing is incorrect for some
reason
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
x Note that you cannot switch between STD (standard time) and DST (daylight
saving time) while UTC* is selected as your Home City.
* Coordinated Universal Time, the world-wide scientific standard of timekeeping. The

To take a direction reading
1. Point the 12 o’clock position of the watch in the direction
@
you want to read.
2. In the Timekeeping Mode, keep the watch horizontal as
you press A.
x The x Second Hand will move to 12 o’clock* and the
direction reading operation will start. After about two
seconds, the x Second Hand will move to indicate
north.
* If the x Second Hand does not point to 12 o’clock, it
could mean that the hand is out of position. Use the
procedure under “To adjust home positions” (page E-81)
to correct the hand position.
x The x Second Hand indicates magnetic north.
x The x Second Hand will continue to move for about 20 seconds after you start
the digital compass operation as it adjusts its magnetic north reading. After that,
the hand will stop at the final reading.
x To take another direction reading, press A again.
x To stop an ongoing direction reading operation and return to the Timekeeping
Mode, press C.
x If you do not perform any operation, the watch will return to normal timekeeping
after about one or two minutes.
3. Press C to return to the Timekeeping Mode.
Note
x If the z Hour Hand stops at 6 o’clock and the c Minute Hand stops at 12 o’clock,
it could mean that the watch has detected abnormal magnetism. For more
information, see “Abnormal magnetism detection is indicated.” (page E-87).

Example: Determining your current position
and your objective on a map
Having an idea of your current location and the
direction to your destination is important when
mountain climbing or hiking. In this example, we
show you how to plot directions on a map and
determine your current location using direction
measurements taken by the watch.
North indicated on the map
1
1. In the Timekeeping Mode, press A.
2. Rotate the map (without moving the watch)
until north on the map is aligned with north as
indicated by the watch’s second hand.
Depending on how the watch is set up, it may
be indicating magnetic north or true north.
1
North indicated by north pointer
Magnetic north: Indicates north in accordance with the Earth’s magnetic field.
True north: Indicates the direction to the North Pole.
x For information about setting the watch up to indicate magnetic north or true
north, see “Magnetic North and True North” (page E-60).
3. Determine your location and destination by checking the map and the geographic
contours around you.
Calibrating Direction Readings
You can use the information in this section to calibrate direction readings, which helps
to improve digital compass accuracy.
Direction Reading Calibration Methods
Important!
x To ensure correct direction readings by this watch, be sure to perform bidirectional
calibration before using it. The watch may produce incorrect direction readings if
you do not perform bidirectional calibration.
E-52
E-53
x Keep the watch away from audio speakers, magnetic necklace, cell phone, and
other devices that generate strong magnetism. Exposure to strong magnetism can
magnetize the watch and cause incorrect direction readings. If incorrect readings
continue even after you perform bidirectional calibration, it could mean that your
watch has been magnetized. If this happens, contact your original retailer or an
authorized CASIO Service Center.
Bidirectional Calibration
x Use this method when using the watch to take readings in an area where magnetic
force is present, or if you notice that the readings produced by the watch are
different from another compass.
Precautions about bidirectional calibration
x 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.
x Do not move the watch while calibration of either direction is in progress.
x 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.
Northerly Calibration
x Use this method to calibrate the watch to detect true north (when it is known by
you).
E-54
E-55
To perform bidirectional calibration

Digital Compass Precautions
Location
Magnetic North and True North
The northerly direction can be expressed either as
True north
magnetic north or true north, which are different from
each other. Also, it is important to keep in mind that
magnetic north moves over time.
Magnetic north
x Magnetic north is the north that is indicated by the
needle of a compass.
x True north, which is the location of the North Pole of
the Earth’s axis, is the north that is normally indicated
on maps.
x The difference between magnetic north and true north
is called the “declination”. The closer you get to the
North Pole, the greater the declination angle.
Earth
x 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.).
x Accurate direction readings are impossible while in a train, boat, air plane, etc.
x 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.
E-60
E-61
Storage
x 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.).
x Whenever you suspect that the watch may have become magnetized, perform the
procedure under “To perform bidirectional calibration” (page E-56).

Troubleshooting
Hand Movement and Position
■ I lost track of what mode the watch is in.
Refer to “Mode Reference Guide” (page E-32). To return directly to the Timekeeping
Mode, hold down C at least two seconds.
■ The x Second Hand is moving at two-second intervals.
■ All the watch’s hands are stopped at 12 o’clock and none of the buttons work
(x Second Hand stopped at 57, 58, 59, or 00).
Power may be low. Expose the watch to light until the x Second Hand starts moving
normally, at one-second intervals (page E-16).
■ The hands of the watch suddenly start moving at high speed, even when I do
not perform any operation.
This could be due to any one of the following causes. In all cases, the hand movement
does not indicate malfunction, and should stop shortly.
x The watch is recovering from a sleep state (page E-19).
E-82
x The time setting is being adjusted following a successful auto time calibration
signal receive operation (page E-20).
■ Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-17). Do not perform any operation
until the hands return to their normal positions (in about 15 minutes). The hands
should return to their correct positions when normal operation returns. To help power
recover, leave the watch in a location where it is exposed to light.
■ The current time setting is off by hours.
x Your Home City setting may be wrong. Check your Home City setting and correct it,
if necessary (page E-36).
E-83
x The period when summer time is applied in the location where you are using the
watch may be different from the period set for your currently selected Home City.
Use the procedure under “To switch between standard time and summer time
manually” (page E-39) to switch from AT (AUTO) to STD (for standard time) or DST (for
summer time).
■ The time and date settings are off.
This could indicate that the watch has been exposed to magnetism or strong impact,
which has caused problems with proper hand and day indicator alignment. Adjust the
watch’s hand and day indicator home position alignment (page E-79).
■ The current time setting is off by one hour.
x If you are using the watch in an area where time calibration signal reception is
possible, see “To configure Home City settings” (page E-36).
E-84
Sensor modes
■ An error is indicated during sensor operation.
Subjecting the watch to strong impact can cause sensor malfunction or improper
contact of internal circuitry. When this happens an error is indicated and the sensor
operation cannot be performed. The illustrations below how sensor mode errors are
indicated.
x During digital compass operations, nearby strong
Digital Compass Mode
magnetism can cause an error to be indicated.
x If the error is indicated during a measurement, restart the
measurement. If an error is indicated when you restart
the measurement, it probably means that there is a
problem with the sensor or internal circuitry.
E-85
■ Abnormal magnetism detection is indicated.
Digital Compass Mode
x Move the watch away from magnetic accessories,
electric devices, computers, and any other devices
that generate strong magnetism, and try performing the
sensor operation again.
x If abnormal magnetism detection is indicated again,
it may mean that the watch case may have become
magnetized or that magnetism conditions are completely
different from those where you last performed
bidirectional calibration. Perform bidirectional calibration
using the procedure under “To perform bidirectional
calibration” (page E-56).
Whenever you have a sensor malfunction, take the watch to your original dealer or
nearest authorized CASIO distributor as soon as possible.
E-86
■ What causes incorrect direction readings?
x The watch may have been exposed to magnetism. Calibrate the direction sensor.
x A 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 such objects and try again.
E-87
Charging
■ The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 3 (page E-16). Continue exposing
the watch to light until the x Second Hand starts moving normally (at one-second
intervals).
■ What causes different direction readings to produce different results at the
same location?
x Magnetism generated by nearby digital noise sources (such as high-tension power
lines) can interfere with the detection of terrestrial magnetism. Move away from the
source of the digital noise and try again.
■ The x Second Hand starts to move at one-second intervals, but then suddenly
returns to moving at two-second intervals.
The watch probably is not sufficiently charged yet. Continue keeping it exposed to
light.
■ 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.
