World Time
The World Time Mode digitally displays the current time in
50 cities (30 time zones) around the world.
•
The times kept in the World Time Mode are
synchronized with the time being kept in the
Timekeeping Mode. If you feel that there is an error in
any World Time Mode time, check the UTC differential of
your Home Site Data (Home City) and the current
setting of the Timekeeping Mode time.
•
Select a city code in the World Time Mode to display the
current time in any particular time zone around the
globe. See the “UTC Differential/City Code List” for
information about the UTC differential settings that are
supported.
•
All of the operations in this section are performed in the
World Time Mode, which you enter by pressing

Illumination
This watch has an EL (electro-luminescent) panel that
causes the entire display to glow for easy reading in the
dark. The watch’s auto light switch turns on illumination
automatically when you angle the watch towards your
face.

The auto light switch must be turned on (indicated by
the auto light switch on indicator) for it to operate.
•
See “Illumination Precautions” for other important
information about using illumination.
To turn on illumination manually
In any mode, press
B

About the Auto Light Switch
Turning on the auto light switch causes illumination to turn on, whenever you position
your wrist as described below in any mode, except for the Hand Setting Mode setting
screen.
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.
•
Wear the watch on the outside of your wrist.

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 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 traffic accident and serious personal injury.

In order to protect against running down the batteries, the auto light switch will turn
off automatically approximately six hours after you turn it on. Repeat the above
procedure to turn the auto light switch back on if you want.

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.
To calibrate the temperature sensor
1. In the Timekeeping Mode, hold down
A
until the
seconds start to flash, which indicates the setting
screen.
2. Press
C
nine times to display the temperature sensor
calibration screen.
3. Use
D
(+) and
B
(–) to change the calibration value.
•
You can change the value in 0.1°C (0.2°F) steps, in a
range of ±10°C (±18°F). The calibration value shows
--
.
-
when the setting is outside the allowable range.
•
To return the calibration value to its default (no calibration, indicated by
- -
), press
D
and
B
at the same time.
•
Temperature sensor calibration will not be possible if the current reading is
outside the allowable display range (–10.0
°
C/14.0
°
F to 60.0
°
C/140.0
°
F) and the
calibration value shows
- -
.
•
Setting a sensor calibration value does not affect temperature values that are
already stored in memory.
