Using the Alarm

You can set fi ve independent daily alarms. When an alarm is turned on, an alarm will sound for about 10
seconds each day when the time in the Timekeeping Mode reaches the preset alarm time. This is true
even if the watch is not in the Timekeeping Mode. One of the daily alarms is a snooze alarm. The snooze
alarm will sound every fi ve minutes up to seven times or until it is turned off.
You can also turn on an Hourly Time Signal, which will cause the watch to beep twice every hour on the
hour.

Illumination

The display of the watch is illuminated 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 (page E-80) for it to operate.

To turn on illumination manually

Press L in any mode to illuminate the display.
You can use the procedure below to select either 1.5 seconds or three
seconds as the illumination duration. When you press L, the display
will remain illuminated for about 1.5 seconds or three seconds,
depending on the current illumination duration setting.
The above operation turns on illumination regardless of the current
auto light switch setting.
Illumination is disabled while confi guring sensor measurement mode
settings, and during bearing sensor calibration.

To change the illumination duration

1. In the Timekeeping Mode, hold down E for at least two seconds. First, SET Hold will fl ash on the
display, and CITY will be displayed in the upper display. After that, the currently selected city code and
city name will scroll across the upper display. Keep E depressed until the scrolling starts.

5. Press E to exit the setting screen.

Press any button.
Note
The snooze alarm sounds up to seven times at intervals of about fi ve minutes.
After the snooze alarm fi rst sounds, SNZ will fl ash on the display until the snooze alarm sounds all
seven times or until it is canceled.
The snooze alarm will be canceled when any of the following occurs while the SNZ indicator is fl ashing
on the display.
- If you turn off the snooze alarm
- If you display the snooze alarm setting screen
- If you display the Timekeeping Mode setting screen
- If your Home City and World Time City are the same city, and you use the World Time Mode to
change the summer time setting of your Home City

To specify standard time or daylight saving time (DST) for a city

1. In the World Time Mode, use A (East) and C (West) to scroll through
the available city codes.
Keep scrolling until the city code whose Standard Time/Daylight
Saving Time setting you want to change is displayed.
2. Hold down E for at least two seconds.
Keep E depressed until the current setting (DST Hold ON or DST
Hold OFF) starts to fl ash on the display.
DST Hold ON means that summer time is enabled, and that the
current time is advanced accordingly. DST Hold OFF means that
summer time is disabled, and that the current time shows standard
time.
This toggles the city code you selected in step 1 between Daylight
Saving Time (DST indicator displayed) and standard time (DST
indicator not displayed).
Using the World Time Mode to change the DST setting of the
city code that is selected as your Home City also will change the
Timekeeping Mode time DST setting.
Note that you cannot switch between standard time/daylight
saving time (DST) while UTC is selected as the World Time City.
Note that the standard time/daylight saving time (DST) setting
affects only the currently selected time zone. Other time zones are
not affected.

settings" (page E-16) for information about how to scroll through setting screens.
3. Press A to toggle the illumination duration between three seconds (3 displayed) and 1.5 seconds (1
displayed).
4. After all of the settings are the way you want, press E twice to exit the setting screen.
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.
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.
