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-15) to conﬁ gure your Home City and daylight saving time settings.

Important!

Proper World Time Mode data depends 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.

Taking Temperature Readings

This watch uses a temperature sensor to measure temperature.

To take temperature readings

Temperature

• Temperature is displayed in units of 0.1°C (or 0.2°F).

• The displayed temperature value changes to

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.

While in the Timekeeping Mode, press D.

TEMP

will appear in the upper display and temperature measurement will start. After about one second, the measurement reading will appear in the upper display.

• The watch will continue to take temperature readings every ﬁ ve

seconds for about two minutes.

• The watch will return to the Timekeeping Mode after the reading

operation is complete (about two minutes).

• Press D to restart temperature readings.

• Pressing C while a reading operation is in progress will stop the

operation and enter the Timekeeping Mode.

Display Units

You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature value. See “To specify the temperature unit” (page E-25).

Temperature Sensor Calibration

The temperature sensor built into the watch is calibrated at the factory and normally requires no further adjustment. If you notice serious errors in the temperature readings produced by the watch, you can calibrate the sensor 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-22

E-23

Operation Guide 5446

To calibrate the temperature sensor

4. Use D (+) and B (−) to calibrate the temperature value with the reading of another instrument.

• Each press of a b utton cha nges the temp erature value i n units of 0.1°C (0.2 °F).

• To return the temperat ure to its uncali brated value (OFF sett ing), press D and B at the same

time.

1. Take a reading with another measurement device to determine the exact current temperature.

2. With the watch in the Timekeeping Mode, press D to enter the Thermometer Mode.

3. Hold down A for about two seconds until the temperature reading disappears from the upper display. Release A at this time, which will cause the temperature reading to ﬂ ash, which indicates the setting mode.

5. Press A to complete calibration and restart the temperature reading operation.

Thermometer Precautions

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.

E-24

Checking the Current Time in a Different Time Zone

You can use the World Time Mode to view the current time in one of 31 time zones (48 cities) around the globe. The city that is currently selected in the World Time Mode is called the “World Time City”.

About the Auto Light Switch

While the Auto Light Switch is enabled, illumination will turn on whenever you position your wrist as described below in any mode.

Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes illumination to turn on.

Warning!

Always make sure you are in a safe place whenever you are reading the display of the watch

•

using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by the auto light switch does not startle or distract others around you.

When you are wearing the watch, make sure that its auto light switch is turned off before riding

•

on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a trafﬁ c accident and serious personal injury.

Auto light switch precautions

• Illumination may not turn on if the face of the watch is more than 15 degrees above

or below parallel. Make sure that the back of your hand is parallel to the ground.

• Illumination turns off after the preset illumination duration (page E-36), even if you

keep the watch pointed towards your face.

• Static electricity or magnetic force can interfere with proper operation of the auto

light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards your face again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again.

• You may notice a very faint clicking sound coming from the watch when it is shaken

back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.

Your Home City setting may be wrong (page E-15). 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” (page E-17) to change the standard time/ daylight saving time (DST) setting.

World Time Mode

The time for my World Time City is off in the World Time Mode.

■

This could be due to incorrect switching between standard time and daylight saving time. See “To conﬁ gure World Time City and summer time settings” (page E-27) for more information.
