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” 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”.

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.

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.

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”.

• The nearby screen shot, for example,

shows what the pointer would indicate 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

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.

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

• To return the currentl y flashing val ue to its initia l factory defa ult settin g, press

one secon d, followed by th e initial defau lt value.

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 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.

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 C to enter the Barometer/Thermometer Mode.

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.
