■ Why is the low battery alert fl ashing?
A low battery indicator appears on the display when battery voltage drops
below a certain level. Availability of some functions becomes limited while
the low battery indicator is displayed. If the low battery indicator remains
on the display, have the battery replaced as soon as possible.
The following describes how display of the low battery indicator affects
watch operation.
• The watch enters the Timekeeping Mode.
• Display illumination becomes disabled.
• Alarm sound becomes disabled.
• Sensor operations become disabled.
Note
• Repeated sensor readings, display illumination, alarm sounds, or use
of other functions over a short period can result in a momentary drop
in battery voltage. This can cause temporary display of the low battery
indicator and limited availability of some watch functions.

Alarms: 5 daily alarms (four one-time alarms; one snooze alarm); Hourly Time Signal
Illumination: Ultraviolet LED (light-emitting diode); Selectable illumination duration (approximately
1.5 seconds or 3 seconds); Auto Light Switch
Other: Button operation tone on/off, Low battery alert
Battery: Two silver oxide batteries (Type: SR927W)
Approximate battery operating time: 2 years under the following conditions:
• 1 illumination operation (1.5 seconds) per day
• Alarm: 10 seconds/day
• Direction readings: 20 times/month
• Temperature readings: Once/week
Frequent use of illumination runs down the battery. Particular care is required when using the auto
light switch (page E-51).

* As of June 2012, the offi cial UTC offset for
Moscow, Russia (MOW) has been changed
from +3 to +4, but this watch still uses an
offset of +3 (the old offset) for MOW. Because
of this, you should leave the summer time
setting turned on (which advances the time by
one hour) for the MOW time.
