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.
• Bidirectional Calibration and Northerly Calibration Bidirectional calibration and northerly calibration calibrate the accuracy of the direction 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.
To perform magnetic declination correction 1. In the Digital Compass Mode, hold down E Magnetic declination for about two seconds until the magnetic angle direction declination angle value starts to flash. This is the setting screen. 2. Use A (+) and C (–) to change the magnetic declination angle value.

Using the Digital Compass While Mountain Climbing or Hiking This section provides three practical applications for using the watch’s built-in digital compass. • Setting a map and finding your current location Having an idea of your current location is important when mountain climbing or hiking.
To set a map and find your current location 1. With the watch on your wrist, position it so the North indicated on the map face is horizontal. 2. In the Timekeeping, Digital Compass, Barometer/Thermometer, or Altimeter Mode, press C to take a compass reading. •...
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-49 for information about how to perform the above step.
• This will position the map in accordance with your current location, so the bearing to your objective is straight ahead of you. To determine the direction angle to an objective on a map and head in that direction 1. Set the map so its northerly indication is aligned with north as indicated by the watch, and determine your current location.
• If you find it difficult to perform the above step while keeping everything aligned, first move into the correct position (12 o’clock position of the watch pointed at the objective) without worrying about the orientation of the map. Next, perform step 1 again to set the map. 3.
4. After setting the map, keep the map and watch pointed in the same direction as you press E to record the currently displayed direction in Bearing Memory. • See “Bearing Memory” (page E-46) for more information. 5. Now you can advance while monitoring the indicator (indicating the direction stored in Bearing Memory) to ensure that it remains in the 12 o’clock position.
Barometer/Thermometer This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature sensor to measure temperature. • You can calibrate the pressure sensor and the temperature sensor (page E-136) if you suspect that readings are incorrect. To take barometric pressure and temperature readings Pressing B in the Timekeeping Mode or in any Pressure...
• The displayed barometric pressure value changes to hPa if a xxxx measured barometric pressure falls outside the range of 260 hPa to 1100 hPa. The barometric pressure value will reappear as soon as the measured barometric pressure is within the allowable range. •...
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 top of each even-numbered hour), regardless of its current mode.
A rising graph generally means improving weather. A falling graph generally means deteriorating weather. Note that if there are sudden changes in weather or temperature, the graph line of past measurements may run off the top or bottom of the display. The entire graph will become visible once barometric conditions stabilize.
Barometric Pressure Differential Pointer This pointer indicates the relative difference between the most recent barometric pressure reading indicated on the barometric pressure graph (page E-56), and the current barometric pressure value displayed in the Barometer/Thermometer Mode (page E-54). • Pressure differential is indicated in the range of ±5 hPa, in 1-hPa units. •...
Current pressure greater than most recent measured pressure hPa values Barometric pressure differential Current pressure less than most recent measured pressure E-59...
About Barometric and Temperature Measurements • Barometric pressure and temperature measurement operations are performed as soon as you enter the Barometer/Thermometer Mode. After that, barometric pressure and temperature measurements are taken every five seconds. • You also can perform a barometric pressure and temperature measurement at any time by pressing B in the Barometer/Thermometer Mode.
Altimeter The watch’s altimeter uses a pressure sensor to detect current air pressure, which is then used to estimate the current altitude based on ISA (International Standard Atmosphere) preset values. You also can specify a reference altitude, which the watch will use to calculate your current altitude based on the value you specify.
• To avoid the effect of sudden temperature changes during measurement, keep the watch on your wrist in direct contact with your skin. • 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.
When you measure altitude using a reference altitude specified by you After you specify a reference altitude, the watch uses that value to convert the current measured barometric pressure value to altitude. • When mountain climbing, you can set the reference value in accordance with a marker along the way or altitude information from a map.
The Altimeter Mode gives you a choice of four different display formats (page E-68). The format you choose determines what type of data is displayed. The Altimeter Mode screen can show any three of the following four items: altitude graph, altitude value, altitude differential, and the current time. You also can select either of the following two altitude measurement types.
To display your current altitude 1. Press A in the Timekeeping Mode or in any Current altitude of the other sensor modes to enter the Altitude Altimeter Mode. graph • The watch will start altitude measurement automatically, and display the result. •...

Radio-controlled Atomic Timekeeping Precautions • Strong electrostatic charge can result in the wrong time being set. • The time calibration signal bounces off the ionosphere. Because of this, such factors as changes in the reflectivity of the ionosphere, as well as movement of the ionosphere to higher altitudes due to seasonal atmospheric changes or the time of day may change the reception range of the signal and make reception temporarily impossible.
• Though this watch is designed to receive both time data (hour, minutes, seconds) and date data (year, month, day), certain signal conditions can limit reception to time data only. • If you are in an area where proper time calibration signal reception is impossible, the watch keeps the time with the precision noted in “Specifications”.
Transmitters The time calibration signal received by this watch depends on the currently selected Home City code (page E-13). • When a U.S. time zone is selected, the watch receives the time calibration signal transmitted from the United States (Fort Collins). •...
When PAR, BER, or ATH is selected as the Home City code: In this case: The watch does this: The first signal search 1. Checks the Mainflingen signal first. operation after the Home City 2. If the Mainflingen signal cannot be code has been changed received, checks the Anthorn signal.
Timekeeping • Resetting the seconds to while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to without changing the minutes. •...
Illumination Precautions • The electro-luminescent panel that provides illumination loses power after very long use. • Illumination may be hard to see when viewed under direct sunlight. • Illumination turns off automatically whenever an alarm sounds. • The watch may emit an audible sound whenever the display is illuminated. This is due to vibration of the EL panel used for illumination, and does not indicate malfunction.
• Illumination may not turn on if the face of the More than 15 degrees watch is more than 15 degrees above or below too high parallel. Make sure that the back of your hand is parallel to the ground. •...
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.
Important! • Incorrectly calibrating the barometric pressure sensor can result in incorrect readings. Before performing the calibration procedure, compare the readings produced by the watch with those of another reliable and accurate barometer. • Incorrectly calibrating the temperature sensor can result in incorrect readings.
To calibrate the pressure sensor and the temperature sensor 1. Press B to enter the Barometer/ Thermometer Mode (page E-11). 2. In the Barometer/Thermometer Mode, hold down E for about two seconds until either OFF or the reference temperature value starts to flash.
3. Use A (+) and C (–) to set the calibration value in the units shown below. Temperature 0.1°C Barometric Pressure 1 hPa • Pressing A and C at the same time returns to the factory calibration (OFF). 4. Press E to return to the Barometer/Thermometer Mode screen. E-139...

• A trained technician will know how to check your watch for proper water resistance whenever you have its battery replaced. Battery replacement requires the use of special tools. Always request battery replacement from your original retailer or from an authorized CASIO Service Center.
• Some water-resistant watches come with fashionable leather bands. Avoid swimming, washing, or any other activity that causes direct exposure of a leather band to water. • The inside surface of the watch glass may fog when the watch is exposed to a sudden drop in temperature.
Should you notice any breakage, discoloration, looseness or other problem with the band, immediately contact your original retailer or an authorized CASIO Service Center to have it checked, repaired, or replaced. Note that you will be charged for any repair or replacement of the band.
Impact • Your watch is designed to withstand impact incurred during normal daily use and light activity such as playing catch, tennis, etc. Dropping the watch or otherwise subjecting it to strong impact, however, can lead to malfunction. Note that watches with shock-resistant designs (G-SHOCK, Baby-G, G-ms) can be worn while operating a chain saw or engaging in other activities that generate strong vibration, or while engage in strenuous sports activities (motocross, etc.).
Electrostatic Charge • Exposure to very strong electrostatic charge can cause the watch to display the wrong time. Very strong electrostatic charge even can damage electronic components. • Electrostatic charge can cause the display to go blank momentarily or cause a rainbow effect on the display. Chemicals •...
• Semi-transparent resin parts can become discolored due to sweat and dirt, and if exposed to high temperatures for long periods. • Contact an authorized CASIO Service Center to have resin components replaced. Note that you will be charged for replacement costs.
Natural Leather and Imitation Leather Bands • Allowing the watch to remain in contact with other items or storing it together with other items while it is wet for long periods can cause the color of the other items to transfer to the natural leather or imitation leather band of the watch.
Metal Components • Failure to clean dirt from a metal band can lead to formation of rust, even if the band is stainless steel or plated. If the watch is exposed to sweat or water, wipe it thoroughly with a soft, absorbent cloth and then store it in a well-ventilated location to dry.
• Allowing the battery to go dead, replacing the battery, or having the watch repaired can cause all data in the watch’s memory to be lost. Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damages or losses caused by data lost due to malfunction or repair of the watch, replacement of the battery, etc.
• Should your band become badly cracked or worn, be sure to have it replaced with a new one. Request band replacement from your original retailer or an authorized CASIO Service Center. Note that you will be charged for band replacement costs, even if your watch is still covered by its warranty.
• Remember that you wear your watch next to your skin, just like a piece of clothing. Because of this, you should always keep your watch clean. Use a soft, absorbent cloth to wipe off any dirt, sweat, water, or other foreign matter from the case and band.
However, charging and discharging of the battery over the years leads naturally to a loss in its ability to sustain a charge and shortens its operating time. If this happens, contact your original retailer or authorized CASIO Service Center. E-12...
