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.

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.

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.

Operation Guide 5176

Altimeter

The watch displays altitude values based on air pressure readings taken by a built-in pressure sensor.

How the Altimeter Measures Altitude

The altimeter can measure altitude based on its own preset values (initial default method) or using a reference altitude speciﬁ ed by you.

When you measure altitude based on preset values

Data produced by the watch’s barometric pressure sensor is converted to approximate altitude based on ISA (International Standard Atmosphere) conversion values stored in watch memory.

When you measure altitude using a reference altitude speciﬁ ed by you

After you specify a reference altitude, the watch uses that value to convert barometric pressure readings to altitude (page E-34).

E-30

• If you leave the watc h in the Altime ter Mode, it wil l update the displ ayed altitude

value regularl y.

• Temperature is meas ured in the Baro meter/T hermome ter Mode and in t he

Altimeter M ode. For det ails about te mperature readi ngs, see "Tempe rature" (page E-24).

3. After you are ﬁ nished using the Altimeter, press Mode and stop auto measurement.

• The watch will re turn to the Tim ekeeping Mo de automatic ally if you do not p erform

any operatio n for about 10 ho urs after ente ring the Alti meter Mode.

Note

• The measurement range for altitude is –700 to 10,000 meters (–2,300 to 32,800

feet).

• The displayed altitude value changes to

measurement range. An altitude value will reappear as soon as the altitude reading is within the allowable range.

E-32

To specify a reference altitude value

• You can set the referen ce altitude val ue within the ra nge of –10,00 0 to 10,00 0

meters (–32,800 to 32,800 feet).

•

Pressing B and D at the same ti me returns to OFF (no referenc e altitude valu e), so the watch per forms air pres sure to altitude c onversions b ased on preset da ta only.

1. In the Altimeter Mode, hold down A until the current reference altitude value starts to ﬂ ash. This is the setting screen.

• Before the referen ce altitude va lue starts to ﬂ as h,

the message SET Hold will appear on the dis play. Keep A depressed u ntil SET Hold disappears.

2. Press D (+) or B (–) to change the current reference altitude value by 5 meters (or 20 feet).

• Specify a re ference altit ude value based o n accurate

altitude information about your current location from a map, etc.

• When mountain climbing, you can specify a reference altitude value in accordance

with a marker along the way or altitude information from a map. After that, the altitude readings produced by the watch will be more accurate than they would without a reference altitude value.

•

Normally, displayed altitude values are based on the watch’s preset conversion values. You also can specify a reference altitude value, if you want. See “Specifying a Reference Altitude Value” below.

• You can change the unit for displayed altitude values to either meters (m) or feet (ft).

See “To specify temperature, barometric pressure, and altitude units” (page E-39).

Specifying a Reference Altitude Value

The altitude readings produced by this watch are subject to error caused by changes in air pressure. Because of this, we recommend that you update the reference altitude value whenever accurate altitude information is available during your climb. After you specify a reference altitude value, the watch adjusts its air-pressure-to-altitude conversion calculation accordingly.

How does the altimeter work?

Generally, air pressure and temperature decrease as altitude increases. This watch bases its altitude measurements on International Standard Atmosphere (ISA) values stipulated by the International Civil Aviation Organization (ICAO). These values deﬁ ne relationships between altitude, air pressure, and temperature.

E-36

Altimeter Precautions

• This watch estimates altitude based on air pressure. This means that altitude

readings for the same location may vary if air pressure changes.

• The semiconductor pressure sensor used by the watch for altitude measurements

is also affected by temperature. When taking altitude measurements, do not subject the watch to temperature changes.

• 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.

• Do not use this watch for measuring altitude in applications that demand

professional or industrial level precision.

• Remember that the air inside of a commercial aircraft is pressurized. Because of

this, the readings produced by this watch will not match the altitude readings announced or indicated the ﬂ ight crew.

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 requires 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.

• 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 hang freely from your bag or in another location where it is not exposed to direct sunlight. Note that removing the watch from your wrist can affect pressure sensor readings momentarily.

Note

• The Stopwatch Mode can indicate elapsed time up to 23 hours, 59 minutes, 59.99

seconds.

• Once started, stopwatch timing continues until you press A to stop it, even if you

exit the Stopwatch Mode to another mode and even if timing reaches the stopwatch limit deﬁ ned above.
