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”.

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 flashing 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 first.

Scrolling

The B and D buttons are used on the setting screen to scroll through data on the display. In most cases, holding down these buttons during a scroll operation scrolls through the data at high speed.

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.

To calibrate the pressure sensor and the temperature sensor

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 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.

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 specified 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 specified by you

After you specify a reference altitude, the watch uses that value to convert barometric pressure readings to altitude.

ABA

Operation Guide 3202

• 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.

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.

•

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”.

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.

To specify a reference altitude value

• You can set the referen ce altitude va lue within th e range 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 referen ce altitude va lue), so the watch per forms air pre ssure to altitu de conversio ns based on pre set data only.

3. Press A to exit the setting screen.

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 define relationships between altitude, air pressure, and temperature.

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 flight 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.

Time Setting

The current time setting is off by hours.

■

Your Home City setting may be wrong. Check your Home City setting and correct it, if necessary.

The current time setting is off by one hour.

■

You may need to change your Home City’s standard time/daylight saving time (DST) setting. Use the procedure under “To change the current time and date settings” to change the standard time/daylight saving time (DST) setting.

Sensor modes

I can’t change the temperature, barometric pressure, and altitude units.

■

When TYO (Tokyo) is selected as the Home City, the altitude unit is set automatically to meters (m), the barometric pressure unit to hectopascals (hPa), and the temperature unit to Celsius (°C). These settings cannot be changed.
