ENGLISH
Congratulations upon your selection of this CASIO watch.
Applications
The built-in sensors of this watch measure barometric pressure, temperature and altitude. Measured values are then shown on the display. Such features make this watch useful when hiking, mountain climbing, or when engaging in other such outdoor activities.

Things to check before using the watch
1. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under “To configure Home City settings” (page E-14) to configure your Home City and daylight saving time settings.
Important!
Proper World Time Mode data depend on correct Home City, time, and date settings in the Timekeeping Mode. Make sure you configure these settings correctly.
2. Set the current time.
See “Configuring Current Time and Date Settings” (page E-17).
The watch is now ready for use.

•For information about selecting a Home City and configuring the DST setting, see “Configuring Home City Settings” (page E-14).
•While 12-hour format is selected for timekeeping, a P (PM) indicator will appear for times from noon to 11:59 p.m. No indicator appears for times from midnight to 11:59 a.m. With 24-hour format, time is displayed from 0:00 to 23:59, without any P (PM) indicator.
•The watch’s built-in full automatic calendar makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except after you have the watch’s battery replaced.

Hand Home Position Correction
The hour and minute hands of the watch can be thrown off by exposure to strong magnetism or impact. The watch is designed to correct the hour and minute hand positions manually.
•All of the operations in this section are performed in the Hand Setting Mode, which you enter by pressing C(page E-11).
To adjust home positions

1. In the Hand Setting Mode, hold down Afor about two |
|
seconds until 0:00 appears on the display. |

|
• This is the home position adjustment mode. |
2. Check the positions of the hour and minute hands.
• The hands are in the correct home positions if they are pointed at 12 o’clock. If they aren’t, use D(clockwise) and B(counterclockwise) to adjust their positions.
3. Press Ato exit the setting screen.

Barometric pressure
To enter and exit the Barometer/Thermometer Mode
1.While in the Timekeeping Mode, press Cto enter the Barometer/Thermometer Mode.
•BARO will appear on the display, indicating that barometric pressure and temperature
measurements are in progress. The measurement results will appear on the display after about five seconds.
•After you press C, the watch will take readings every five seconds for the first three minutes, and then every two minutes after that.
E-23
2.Press Cfive times to return to the Timekeeping Mode.
•The watch will return to the Timekeeping Mode automatically if you do not perform any operation for about one hour after entering the Barometer/Thermometer Mode.
Barometric Pressure
•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.
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-39).
Pressure Differential Level Indicator
Pressure |
This indicator shows the relative difference between the |

Interpreting Barometric Pressure Differential Levels
Pressure differential is indicated in the range of ±5 hPa, in 1-hPa units.
If the level indicator is here: |
It means this: |
Plus (+) side |
Pressure is rising and weather will tend to improve. |
Minus (–) side |
Pressure is falling and weather will tend to deteriorate. |
•The nearby screen shot, for example, shows the level indicator when the calculated pressure differential is approximately –3 hPa (approximately –0.09 inHg).

•Barometric pressure is calculated and displayed using hPa as the standard. The
barometric pressure differential also can be read in inHg units as shown in the illustration (1 hPa = 0.03 inHg).
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.
Important!
•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.
E-27
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, press Cto enter the Barometer/Thermometer Mode.
3. Hold down Auntil the current temperature value starts to flash on the display. This is the setting screen.
•Before the temperature value starts to flash, the message SET Hold will appear on the display.
Keep Adepressed until SET Hold disappears.
4. Press Cto move the flashing between the temperature value and barometric pressure value, to select the one you want to calibrate.
E-28
5. Use D(+) and B(–) to adjust the calibration value in the units shown below.
Temperature |
0.1°C (0.2°F) |
Barometric Pressure |

•To return the currently flashing value to its initial factory default setting, press B and Dat the same time. OFF will appear at the flashing location for about one second, followed by the initial default value.
6.Press Ato return to the Barometer/Thermometer Mode screen.
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.
