Deleting an Altitude Measurement Record
Use the Recall Mode to delete altitude measurement records. You can enter
the Recall Mode by pressing D.
Note
• The procedure you should use to delete a record depends on if the record
was produced by Auto measurement or Manual measurement.
• Deleting Auto measurement records deletes the entire set, from the initial
record to the final record.
• You cannot delete a record that is part of an ongoing Auto measurement
operation (indicated when AUTO is flashing on the display). You can,
however, delete records from another, already completed measurement
operation.
To delete a altitude measurement record
1. In the Recall Mode, display the record you
want to delete.
• If you want to delete a set of Auto
measurement records, display the first
record of the set.
2. To clear the data, hold down A until the
watch emits a long beep (and until CLR
stops flashing on the display). First record of the set

When an alarm is turned on, the alarm tone
sounds when the alarm time is reached. You
can also turn on an Hourly Time Signal that
causes the watch to beep twice every hour on
the hour.

an alarm screen. SIG appears in place of
AL when the Hourly Time Signal screen is
shown.
• All of the operations in this section are
performed in the Alarm Mode, which you
enter by pressing D.
To set an alarm time
1. In the Alarm Mode, use E and B to
select the alarm whose time you want to
set.
2. Hold down A until the hour digits of the alarm time start to flash, which
indicates the setting screen.
• This automatically turns on the alarm.
3. Press D to move the flashing between the hour and minutes.
4. While a setting is flashing, use E (+) and B (–) to change it.
• When setting the alarm time using the 12-hour format, take care to set
the time correctly as a.m. (no indicator) or p.m. (P indicator).

BACKLIGHT
The backlight uses an EL (electro-
luminescent) panel that causes the entire
display to glow for easy reading in the dark.
The watch’s auto light switch automatically
turns on the backlight 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 “Backlight Precautions” for other
important information about using the
backlight.
To turn on the backlight manually
In any mode, press L to illuminate the display for about one second.
• The above operation turns on the backlight regardless of the current auto
light switch setting.
About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on for about one
second, whenever you position your wrist as described below in any mode.
• Be sure to wear the watch on the outside of your left wrist while using the
auto light switch.
Moving the watch to a position that is parallel to the ground and then tilting
it towards you more than 40 degrees causes the backlight 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 surprise 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 traffic
accident and serious personal injury.
