•The DST indicator will be on the upper display while daylight saving time is turned on.
Note
•After you specify a city code, the watch will use UTC* offsets in the World Time Mode to calculate
the current time for other time zones based on the current time in your Home City.
* Coordinated Universal Time, the world-wide scientific standard of timekeeping.
The reference point for UTC is Greenwich, England.
To change the daylight saving time (summer time) setting
1. In the Timekeeping Mode, hold down Auntil ADJ appears in the

Configuring Current Time and Date Settings
You can use the procedure below to adjust the Timekeeping Mode time and date settings if they are off.
Changing the digital Home City data should cause the analog time setting to change accordingly. If the
analog time does not indicate the digital time, check the home positions of the hands and make
adjustments if necessary (page E-20).
To change the current time and date settings
1. In the Timekeeping Mode, hold down Auntil ADJ appears in the
upper display.
•When you release A(after ADJ appears), city code will be flashing
in the upper display.

Hand Home Position Adjustment
Strong magnetism or impact can cause the hands of the watch to be off.
•Home position adjustment is not necessary when the analog time and digital time are the same time in
the Timekeeping Mode.
To adjust home positions
1. In the Timekeeping Mode, hold down Aand keep it depressed for
about five seconds until H.SET appears on the upper display.
•When you release Aafter H.SET appears, the second hand will
move to 12 o’clock. This indicates the second hand home position
adjustment mode.
•Though ADJ will appear in the upper display about two seconds
after you hold down A, do not release the button yet. Keep it
depressed until H.SET appears.
•Home position adjustment is performed in the following sequence:
second hand, current time hour and minute hand, World Time hour
and minute hand, mode hand.

•If the selected hand does not move exactly to 12 o’clock, perform step 3 below to adjust it.
•The watch will return to regular timekeeping automatically if you do not perform any operation for
about two or three minutes. Any changes you have made to settings up to that point will be saved.
3. Use D(+) and B(–) to adjust the position of the currently selected hand.
•Holding down either button will cause the hand to move at high speed. Once started, high-speed
hand movement will continue even if you release the button. To stop high-speed hand movement,
press any button.
•The second hand and mode dial hand will automatically stop high-speed movement after they
complete one revolution. The minute hand will stop automatically after 12 revolutions.

Taking Temperature Readings
This watch uses a temperature sensor to measure temperature.
To take temperature readings
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 five
seconds for about two minutes.
•The watch will return to the Timekeeping Mode after the reading
operation is complete (about two minutes).
•Press Dto restart temperature readings.
•Pressing Cwhile a reading operation is in progress will stop the
operation and enter the Timekeeping Mode.
Temperature
•Temperature is displayed in units of 0.1°C (or 0.2°F).
•The displayed temperature value changes to - - - °C (or °F) if a measured 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.
TemperatureTemperature
E-23
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.
