Operation Guide 5176

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.

Warning !

Things to check before using the watch

1. Check the Home City and the daylight saving time (DST) setting.

Use the procedure under “To conﬁ gure Home City settings” (page E-14) to conﬁ gure 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 conﬁ gure these settings correctly.

2. Set the current time.

See “Conﬁ guring Current Time and Date Settings” (page E-17).

The watch is now ready for use.

General Functions (All Modes)

The functions and operations described in this section can be used in all of the modes.

Auto Return Features

• The watch returns to the Timekeeping Mode automatically if you do not perform any

button operation for two or three minutes in the Alarm 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.

•

If you leave a setting screen with ﬂ ashing digits on the display for two or three minutes without performing any operation, the watch exits the setting screen automatically.

Initial Screens

When you enter the World Time Mode or Alarm Mode, the data you were viewing when you last exited the mode appears ﬁ rst.

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).

Barometric Pressure

• Barometric pressure is displayed in units of 1 hPa (or 0.05 inHg).

•

The displayed barometric pressure value changes to 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

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.

1. In the Hand Setting Mode, hold down A for 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 hand s are in the corre ct home posi tions if they are

pointed at 12 o’clock. I f they aren’t, u se D (clockwise) and B (counterclock wise) to adjust their positi ons.

3. Press A to exit the setting screen.

• This will cause the hour and minute hands to move to

• For information about selecting a Home City and conﬁ guring the DST setting, see

“Conﬁ guring 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 (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.

Barometer/Thermometer

This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature sensor to measure temperature.

To enter and exit the Barometer/Thermometer Mode

1. While in the Timekeeping Mode, press C to enter the Barometer/Thermometer Mode.

• BARO will appea r on the display, indic ating

that baromet ric pressure an d temperature measurem ents are in progre ss. The mea surement results will a ppear on the di splay after abo ut ﬁ ve seconds.

• After you press C, the watch will take readings every

ﬁ ve seconds fo r the ﬁ rst three mi nutes, and th en every two mi nutes after t hat.

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).

barometric pressure differential also can be read in inHg units as shown in the illustration (1 hPa

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.

UseD (+) and B (–) to adjust the calibration value in the units shown below.

Temperature 0.1°C (0.2°F) Barometric Pressure 1 hPa (0.05 inHg)

6. Press A to 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 ofﬁ cial 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.
