AUTO m °C RECALL A S ▼ ▼ Alarm Mode Stopwatch Mode ▼ A A S BACKLIGHT B A P A This watch features an electroluminescent (EL) backlight that helps you easily read the face, even in total darkness. Its auto light switch automatically lights the watch face whenever you turn your wrist towards your face. • The auto light switch on indicator is shown on the display in all modes while the auto light switch is on. • In order to protect against running down the battery, the auto light switch is automatically turned off approximately six hours after you turn it on. Repeat the above procedure to turn the auto light switch back on if you want. • Pressing B in any mode (except for the Recall Mode) illuminates the display for about two seconds, regardless of the auto light switch on/off setting. S C About the auto light switch D While the auto light switch is turned on, the backlight automatically lights for about two seconds in any mode whenever you position your wrist as described below. E Notes • The backlight of the watch employs an electroluminescent (EL) light, which loses illuminating power after very long use. • Frequent use of the backlight shortens the battery life. • The illumination provided by the backlight may be hard to see when viewed under direct sunlight. • The watch will emit an audible sound whenever the display is illuminated. It does not indicate malfunction of the watch. • The backlight automatically turns off whenever an alarm sounds. Important! Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light switch to operate when it is not needed, which shortens battery life. Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes the backlight to illuminate. To manually turn on the backlight Parallel to ground In any mode (except for the Recall Mode), press B to illuminate the display for about two seconds. More than 40° To switch the auto light switch on and off In the Timekeeping Mode, hold down D for one or two seconds to turn the auto light switch on and off.

Make sure that the back of your hand is parallel to the ground. A S OFF S More than 15 degrees too high More than 15 degrees too low 1998/2198-2 • The backlight turns off in about two seconds, 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 the backlight does not illuminate, try moving the watch back to the starting position (parallel with the ground) and then tilt it back toward you 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. • Under certain conditions the backlight may not light until about one second or less after turn the face of the watch towards you. This does not necessarily indicate malfunction of the backlight. Warning! • Never try to read your watch when mountain climbing or hiking in areas that are dark or in areas with poor footing. Doing so is dangerous and can result in serious personal injury. • Never try to read your watch when running where there is the danger of accidents, especially in locations where there might be vehicular or pedestrian traffic. Doing so is dangerous and can result in serious personal injury. • Never try to read your watch when riding on a bicycle or when operating a motorcycle or any other motor vehicle. Doing so is dangerous and can result in a traffic accident and serious personal injury. • 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 and unintended operation of the auto light switch can create a distraction, which can result in a traffic accident and serious personal injury. To enter and exit the Digital Compass Mode 1. In any mode (except for the Alarm Mode), press E to enter the Digital Compass Mode. • At this time, the watch immediately starts a Digital Compass operation. After about one second, the direction that the 12 o’clock position of the watch is pointing appears on the display. • If you do not perform any button operation for a few minutes, the watch automatically returns to the mode you were in before entering the Digital Compass Mode. 2. Press C to return to the mode you were in before entering the Digital Compass Mode. • Note that when you enter the Digital Compass Mode from the Altimeter Mode, the Altimeter Mode measurement (see “About altitude measurements”) continues to be performed internally. To take a direction reading without storing data into memory 1. Place the watch on a flat surface or (if you are wearing the watch), make sure that Date your wrist is horizontal (in relation to the Direction horizon). • Note that taking a measurement while the B A watch is not horizontal (in relation to the horizon) can result in large measurement error. 2.

ENE SSE Meaning Eastnortheast Southsoutheast Westsouthwest Northnorthwest 4. Next, you can adjust the rotary direction bezel so that the “N” or “ ” mark is aligned with the magnetic north indicator. This correctly aligns all of the markings on the bezel. • The Digital Compass operation is automatically interrupted whenever an alarm (Daily Alarm or Hourly Time Signal) sounds. If this happens, start the Digital Compass operation again from the beginning. To take a direction reading and store data into memory DIGITAL COMPASS FUNCTIONS This watch features a built-in bearing sensor that indicates any one of 16 directions. Up to five sets of direction readings can be stored into memory. Each set of data includes the direction, along with the date and time of the measurement. Direction readings can be performed in the Digital Compass Mode. B A A BEARING C S D 1. While in the Digital Compass Mode, use D to select the memory area where you want to store the data. Each time you press D, the selected memory area changes in the following sequence. Normal Screen Memory 1 Memory 2 Memory 5 Memory 4 Memory 3 E Memory number (memory area screen only) 1998/2198-3 • Each memory area is identified by a number from 1 through 5. The Normal screen shows the current time and date without a memory number. • If the memory area you select already contains data, that data appears on the display whenever the memory area is selected. Performing a Digital Compass operation replaces the existing data with the newly measured data. 2. Use the same procedures as described in steps 1 through 4 under “To take a direction reading without storing data into memory”. • The more correctly you perform bidirectional calibration, the better the accuracy of your Digital Compass readouts. You should perform bidirectional calibration whenever you change environments where you use the Digital Compass, and whenever you feel that the Digital Compass is producing incorrect readings. To perform bidirectional calibration B A To recall data from memory Magnetic north indicator Direction Date While in the Digital Compass Mode, use D to scroll through the data in the following sequence. A BEARING B A Normal Screen Memory 1 Memory 2 Memory 5 Memory 4 Memory 3 S C D E P A BEARING C To delete data S 1. While in the Digital Compass Mode, scroll through the data items and display the one you want to delete. 2. Hold down A until the displayed value Memory No. changes to “– – –”. • Holding down A causes the message “CLR” to appear on the display, followed by the value changing to “– – –”. 1. While in the Digital Compass Mode (Normal screen), hold down A until the upper display changes to show “–1–”. • At this time, the magnetic north indicator flashes at the 12 o’clock position to indicate that the watch is ready to calibrate the first direction. 2. Place the watch on a level surface, and press E to calibrate the first direction. • When the calibration procedure is complete, the message “OK” appears in the upper display. This soon changes to “–2–” and the magnetic north indicator flashes at the 6 o’clock position to indicate that the watch is ready for the second direction. D E Time Direction value Digital Compass Precautions This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that the northern direction 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 • Using the Digital Compass when you are near a source of strong magnetism can cause large errors in readings. Because of this, you should avoid using the Digital Compass 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 measurements are impossible while in a train, boat, air plane, etc. • Accurate measurements are also impossible indoors, especially inside ferroconcrete structures. This is because the metal framework of such structures picks up magnetism from appliances, etc. 3. Rotate the watch 180 degrees. 4. Press E again to calibrate the second direction. • When the calibration procedure is complete, the message “OK” appears in the upper display. After a short while, the watch automatically returns to the Digital Compass Mode. 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 readings from the Digital Compass. • Do not move the watch during the one or two seconds (from the point you press E up to the point that “OK” appears in the upper display) that the calibration of each direction is in progress. If you do, the message “ERR” appears in the upper display. When this happens, restart the bidirectional calibration procedure from the beginning. • The appearance of “ERR” during bidirectional calibration can also be caused by local interference. If you suspect that this is the case, move to another location and try the procedure again. • You should perform bidirectional calibration in an environment that is the same as that where you plan to be using the Digital Compass. If you plan to use it in an open field, for example, calibrate in an open field. To perform northerly calibration B A Calibrating the Digital Compass Whenever you suspect that the readings produced by the Digital Compass are wrong, you should calibrate it. You can use either one of two calibration procedures: bidirectional calibration or northerly calibration. You should use bidirectional calibration when you want to calibrate the Digital Compass to operate within an area exposed to magnetic force. This type of calibration should be used if the watch become 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). You could use this calibration procedure, for example, to set the watch to indicate true north instead of magnetic north. Important! • If you want to perform both bidirectional and northerly calibration, be sure to perform bidirectional calibration first, and then perform northerly calibration. This is necessary because bidirectional calibration cancels any previously set northerly calibration setting. • If you do not perform any button operation for two or three minutes while either calibration procedure is in progress (while the magnetic north indicator is flashing at the 12 or 6 o’clock position), the watch automatically returns to the Digital Compass Mode. S D E Storage • The precision of the compass may deteriorate if the watch becomes magnetized. Because of this, you should be sure to 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 one of the calibration procedures under “Calibrating the Digital Compass”. A BEARING C 1. While in the Digital Compass Mode (Normal screen), hold down A until the upper display changes to show “–1–”. 2. Press C to start the northerly calibration procedure. • At this time, the indicator “N” appears in the upper 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). 4. Press E to start the calibration operation. • When the calibration procedure is complete, the message “OK” appears in the upper display. After a short while, the watch automatically returns to the Digital Compass Mode. CHANGING THE MEASUREMENT UNITS You can change the measured values displayed by the watch between the following units. Altitude: meters (m) ↔ feet (ft) Temperatures: Celsius (°C) ↔ Fahrenheit (°F) Barometric Pressure: hecto-pascals/millibars (hPa/mb) ↔ inchesHg (inHg) Some countries call to this unit as hecto-pascal (hPa), while other countries call it millibars (mb). It really makes no difference, because 1 hPa = 1 mb. In this manual, we will refer to hPa/mb or hPa (mb). Important! • Certain measurement functions are automatically terminated when you change the measurement units. Be sure that you perform this operation before starting actual measurements. • Changing the altitude unit of measurement automatically switches off the altitude alarm, and sets the alarm’s value to zero. • Changing the barometric pressure unit of measurement automatically restarts the barometric pressure graph from a new value. • Changing any of the units of measurement immediately starts to display newly measured data in the unit you specify. It also affects the unit of measurement for any data already stored in memory. 1998/2198-4 To change the measurement units B A hPa mb °C A S C D Understanding the altimeter display 1. Use C to enter the Timekeeping Mode. 2. Press D until the Barometric Pressure/ Temperature screen appears. 3. Hold down A until “OFF” (or the temperature value) appears flashing in the display.

AL Memory measurements ALTIMETER FUNCTIONS A built-in altimeter uses a pressure sensor to detect the current air pressure which is then used to estimate the current altitude in accordance with ISA (International Standard Atmosphere) values for altitude and air pressure. If you preset a reference altitude, the watch will also calculate the current relative altitude based on your preset value. Altimeter functions also include data storage memory and an altitude alarm. Memory measurements are taken independently of Altimeter Mode measurements and stored directly into memory (along with temperature measurements) for later recall. With memory measurement, the watch continuously performs measurements whenever the minutes in the Timekeeping Mode reach 00, 15, 30, or 45, until you switch memory measurements off. The watch continues to take measurements regardless of whether or not you change modes, so you can keep a running log of altitude and temperature changes automatically. Important! About the memory... • This watch estimates altitude based on air pressure. This means that altitude readings for the same location may vary if air pressure changes. • Sudden changes in the weather make it impossible to produce accurate altitude readings. • This watch employs a semiconductor pressure sensor, which is affected by temperature changes. When taking altitude measurements, be sure to do so while ensuring that the watch is not exposed to temperature changes. • Do not use this watch while participating in sports where there are sudden altitude changes. Also, do not use this watch for applications that demand professional or industrial level precision. This watch should not be used while engaging in the following activities: sky diving, hang gliding, paragliding, gyrocopter riding, glider riding, etc. The memory item stored by the watch consists of the current altitude, plus the date, time, and temperature. Data is stored in the same sequence that it is input. Memory can hold a total of 50 sets of data, which is enough to store 12 hours and 15 minutes of memory data. See “To recall altitude measurement data from memory” for details on how to recall memory data. Applications When no reference altitude is preset: • The watch produces approximate altitude readings. When a reference altitude is preset: • Before beginning the climb, set the reference altitude to 0 m at the foot of the mountain. This makes it possible to determine the difference in altitude between the reference point and your destination. • To determine the height of a tall building, set the reference altitude to 0 m on the ground floor. Note, however, that if the building is pressurized or air conditioned, you may not be able to get a good reading. • To determine the difference in altitude between your house and the another location, set the reference altitude to 0 m at your house, and then check the reading when you arrive at the other location. About altitude measurements There are two types of altitude measurements: those for displayed data (Altimeter Mode measurements) and those for memory data (see “Memory measurements”). Altimeter mode measurement This type of measurement is performed only when the watch is in the Altimeter Mode. As soon as you enter the Altimeter Mode, measurements are taken every five seconds for the first three minutes. After that, measurements are taken every two minutes. The display unit for Altimeter Mode measurements is 5 m (20 feet), and the measurement range is 0 to 6,000 m (0 to 19,680 feet). • The measured altitude may be a negative value in cases where there is a reference altitude value set or because of certain atmospheric conditions. Important! Further memory measurements become impossible whenever memory is full. If you try to perform Memory measurement while memory is full, the watch beeps for three seconds and the message FULL appears on the display. Always check the amount of memory remaining before starting memory measurements, and delete data if necessary. ALTI A S To store altitude data into memory (memory measurement) Auto memory indicator B A AL AUTO m °C P ALTI C A S D 1. In the Altimeter Mode, hold down D until the watch emits a short beep, indicating the start of the measurement. • The data measured when you first start memory measurement is also stored into memory. • The “AUTO” indicator flashes on the display when you start memory measurements. The “AUTO” indicator continues to flash (indicating that measurements continue) even if you change modes. E • Auto memory measurement cuts off automatically whenever there are 49 sets of data stored in memory. The 50th set of data measured when you stop the measurement operation in step 2 below is also stored in memory. 2. To stop measurements at any point, hold down D again until the watch emits a short beep. • A final measurement is taken when you switch memory measurement off, and that data is also stored into memory. Such data is indicated by “FIN” during the recall operation. 1998/2198-5 Example: When the initially measured altitude is less than the altitude Setting a Reference Altitude After you set a reference altitude, the watch automatically calculates the difference between the current altitude and your preset value. The altitude measurements produced by this watch are subject to error caused by changes in air pressure. Because of this, we recommend that you set the reference altitude during your climb whenever one is available. B A AL AUTO m ALTI A S C D 1. In the Altimeter Mode, hold down A until the display clears. After 4 or 5 seconds, either “OFF” or the current reference altitude value (if set) will start to flash. The data flashes because it is selected. • The “OFF” indicator appears when the factory setting is being used for the calibration. E 2. Press D to increase the current reference altitude value by 5 m or B to decrease it. Holding down either button changes the value at high speed. • If you have selected feet as your unit of measurement, the above operations change the reading in increments of 20 feet. • You can set the reference altitude within the range of –6,000 m to 6,000 m (–19,680 feet to 19,680 feet). • Pressing B and D at the same time returns to the “OFF” message. 3. After setting the reference altitude you want, press A to return to the Altimeter Mode. alarm setting. Altitude alarm setting The graphic display would appear as illustrated here when your current altitude is 700 meters, after you set the altitude alarm for 1,000 meters and the initial measurement was 0 meters. Note that seven segments of the graph are darkened because you are 7/10 of the way to the value set for the altitude alarm. Current altitude • Segments in the graphic display darken as you approach the altitude alarm setting. If you descend away from the altitude alarm setting, the darkened segments are cleared from the graphic display. • All 10 segments are darkened when you reach or exceed the altitude set for the altitude alarm. • If your current altitude is lower than that registered for the initial measurement, none of the graphic display segments are darkened. Example: When the initially measured altitude is greater than the altitude alarm setting. Altitude alarm setting The graphic display would appear as illustrated here when your current altitude is 1,500 meters, after you set the altitude alarm for 1,000 meters and the initial measurement was 2,000 meters. Note that five segments of the graph are darkened because you are 5/10 of the way to the value set for the altitude alarm. About the Altitude Alarm The altitude alarm sounds for about five seconds whenever the current altitude matches a preset value. You can press any button to stop the alarm after it starts to sound. Example If you set the altitude alarm at 130 meters, it sounds when you pass the 130meter mark on your way up and on your way back down. To set the altitude alarm 1. In the Altimeter Mode, hold down A until the display clears. After 4 or 5 seconds, either “OFF” or the current reference altitude value (if set) will start to flash.

After setting the altitude alarm value, press A to return to the Altimeter Mode. To switch the altitude alarm on and off 1. In the Altimeter Mode, hold down A until the display clears. After 4 or 5 seconds, either “OFF” or the current reference altitude value (if set) will start to flash. The data flashes because it is selected. 2. Press E to switch the altitude alarm on and off. • The indicator “ AL ” is shown on the display while the altitude alarm is on. 3. After switching the altitude alarm on or off, press A to return to the Altimeter Mode. • If the altitude alarm is on, the altitude alarm indicator remains on the display when you change to another mode. About the graphic display In the Altimeter Mode, the graphic display normally indicates the counting of the current time’s seconds. When a memory measurement operation is being performed while the altitude alarm is on, however, the watch automatically divides the graphic display into 10 equal parts. Each part represents 1/10 of the difference between the first altitude measured by the memory measurement operation and the value you set as the altitude alarm. The graphic representation gives you some idea of how much farther you must go to reach the altitude indicated by the altitude alarm setting. • The graphic representation described below is not shown on the display if the altitude alarm is switched off. Current altitude • Segments in the graphic display darken as you approach the altitude alarm setting. If you ascend away from the altitude alarm setting, the darkened segments are cleared from the graphic display. • All 10 segments are darkened when you reach or exceed the altitude set for the altitude alarm. • If your current altitude is higher than that registered for the initial measurement, none of the graphic display segments are darkened. To recall altitude measurement data from memory 1. Use C to enter the Recall Mode. 2. Press D to scroll forward through the stored data items or B to scroll backward. • Holding down either button scrolls through the data items at high speed. • The data item that is displayed when you exit the Recall Mode is still displayed the next time you enter the Recall Mode.

This sensor can be calibrated. Important! To calibrate the barometric pressure 1. Display the barometric pressure and temperature in the Timekeeping Mode. 2. Hold down A until the display clears. “OFF” or the temperature value should be flashing on the display. ° 3. Press C to show the barometric pressure calibration display. At this time, “OFF” or the barometric pressure value should be flashing on the display. C D • The “OFF” indicator appears when the E factory setting is being used for the calibration. 4. Each press of D increases the displayed barometric pressure by 1 hPa/ mb, while pressing B decreases it. Holding down either button changes the value at high speed. • If you have selected inHg as your unit of measurement, the above operations change the reading by 0.05 inHg. • Pressing B and D at the same time returns to the “OFF” display. 5. After calibrating the barometric pressure, press A to return to the Barometric Pressure/Temperature screen. • If you do not operate any button for a few minutes while the barometric pressure digits are flashing, the flashing stops and the watch goes back to the Barometric Pressure/Temperature screen. B A hPa mb The barometer that is 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. Example barometer applications • Before going mountain climbing, you can take readings to find out the probable upcoming weather. • You can predict the weather for golf or other outdoor activities. About barometric measurements The barometer automatically takes measurements every two hours (starting from midnight), regardless of what mode you are in. The last measurement result, along with the current temperature is displayed in the Timekeeping Mode. Understanding the barometer screen C A 1. Use C to enter the Timekeeping Mode. 2.

The normal display will return as soon as the pressure returns within the allowable range. Using the barometric pressure graph Changes in barometric pressure are caused by changes in the weather and temperature. The following shows how to interpret the data that appears on the barometric pressure graph. A rising graph generally means better weather. S THERMOMETER FUNCTIONS A built-in temperature sensor measures temperature and shows the measured value on the display. The thermometer can be calibrated. Important! 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 off all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature. About temperature measurements Temperature measurements are taken automatically every five minutes, regardless of what mode the watch is in. Measured temperature values can be viewed in the Timekeeping or Altimeter Modes. Temperature measurements are taken every five seconds for the first three minutes after you display the Timekeeping Mode’s barometric pressure/temperature display, or after you enter the Altimeter Mode. After that, temperature measurements are taken every five minutes. • Temperature measurement data can be recalled along with altitude measurement data. Understanding the temperature screen 1.

QUESTIONS & ANSWERS Question: What causes incorrect direction readings? Answer: • Incorrect bidirectional calibration. Perform bidirectional calibration. Remember that bidirectional calibration is required whenever batteries are replaced. • 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 Digital Compass operation on a train, boat, etc. Move away from large metal objects and try again. Note that digital compass operation cannot be performed inside a train, boat, etc. Question: What causes the Digital Compass to produce different readings at the same location? Answer: • Direction being measured is somewhere between two measurable directions (N and NNW, for example). The Digital Compass is designed to indicate any one of 16 different directions. If you move the 12 o’clock position slightly to the left or right (to move it off of the point between the two measurable directions), the Digital Compass should consistently produce the same reading. • Magnetism generated by nearby high-tension wires are interfering with reception of terrestrial magnetism. Move away from the high-tension wires and try again. Question: What does it mean when “– – –” appears in place of a direction? Answer: This is the abnormal magnetic field indicator. It means that strong magnetism is being generated nearby. Move away from the source of strong magnetism and try again. Question: Why am I having problems performing Digital Compass operations indoors? Answer: TV, personal computer, speakers, or some other object is interfering with terrestrial magnetism. Move away from the object causing the interference or perform the Digital Compass operation outdoors. Indoor Digital Compass operations are particularly difficult inside ferroconcrete structures. Remember that you cannot perform Digital Compass operations inside of trains, airplanes, etc. Question: How does the altimeter work? Answer: Generally, air pressure and temperature decrease as altitude increases. This watch is equipped with a pressure sensor and bases its altitude measurements on International Standard Atmosphere (ISA) values stipulated by the International Civil Aviation Organization (ICAO), which define relationships between altitude, air pressure, and temperature.

Absolute altitude expresses an absolute height above sea level. Relative altitude expresses the difference between the height of two different places. Height of building 130m (Relative altitude) Rooftop at an altitude of 230m above sea level (Altitude above sea level) Sea A 400 • Be sure to recalibrate at Point B if changing weather conditions produce altitude reading errors. • The following conditions will prevent you from obtaining accurate readings: Air pressure changes because of changes in the weather Extreme temperature changes Subjecting the watch to strong impact Precautions Concerning Simultaneous Measurement of Altitude and Temperature Though you can perform altitude and temperature measurements at the same time, you should remember that each of these measurements require 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. The following describes what you should do to give priority to either altitude or temperature. • 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 hand freely from your bag or in another location where it is not exposed to direct sunlight. Question: How does the barometer work? Answer: Barometric pressure indicates changes in the atmosphere, and by monitoring these changes you can predict the weather with reasonable accuracy. Rising atmospheric pressure indicates good weather, while falling pressure indicates deterioration weather conditions. The barometric pressure that you see in the newspaper and on the TV weather report are measurements corrected to values measured at 0 m sea level. Question: What should I do if I lose track of which mode I am in or lose my way when making settings? Answer: Hold down the C button for two or three seconds to return to the Timekeeping Mode. Next, try performing the operation you want again. About 6.5°C per 1,000 m Source: International Civil Aviation Organization ALTITUDE B 1. At Point A, calibrate the altimeter to 400 meters. 2. Proceed from Point A to Point B, taking altimeter measurements along the way. • If you also have altitude data for Point B, you should again calibrate the altimeter there. –24°C 540hPa/mb 1013hPa/mb When you are out hiking or mountain climbing, calibrate the altimeter using an altitude value from another source (a signpost or map, for example). Do this just before you start your altitude measurements. • The measurement functions built into this watch are not intended for use in taking measurements that require professional or industrial precision. Values produced by this watch should be considered as reasonably accurate representations only. • When engaging in mountain climbing or other activities in which losing your way can create a dangerous or life-threatening situation, always be sure to use a second compass to confirm direction readings. • CASIO COMPUTER CO., LTD. assumes no responsibility for any loss, or any claims by third parties that may arise through the use of this watch.
