•
The
LOW
indicator flashes on the display in the Timekeeping Mode when battery is
at Level 3.
•
The
LOW
indicator at Level 3 and the flashing charge indicator (
CHG
) at Level 4 tell
you that battery power is very low, and that exposure to bright light for charging is
required as soon as possible.
•
At Level 5, all functions are disabled and settings return to their initial factory
defaults. Functions are enabled once again after the rechargeable battery is
charged, but you need to set the time and date, after the battery reaches Level 4
(indicated by the flashing charge indicator) from Level 5. You will not be able to
configure any of the other settings until the battery reaches Level 3 (no charge
indicator) after dropping to Level 5.
•
Leaving the watch in direct sunlight or some other very strong light source can cause the
battery power indicator to show a reading momentarily that is higher than the actual
battery level. The correct battery power indicator should appear after a few minutes.
•
If you use the light or alarms a number of times during a short period, the recover
indicator (
RECOV
) appears and the following operations become disabled until
battery power recovers.
Illumination
Beeper tone
Time calibration signal reception
After some time, battery power will recover and the recover indicator will disappear,
indicating that the above functions are enabled again.
Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid leaving
the watch in the areas described below whenever charging its rechargeable battery.
Also note that allowing the watch to become very hot can cause its liquid crystal
display to black out. The appearance of the LCD should become normal again when
the watch returns to a lower temperature.
Warning!
Leaving the watch in bright light to charge its rechargeable battery can cause it
to become quite hot. Take care when handling the watch to avoid burn injury.
The watch can become particularly hot when exposed to the following
conditions for long periods.

Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signals transmitted from Rugby and Mainflingen include both
Standard Time and DST data. When the Auto DST setting is turned on, the watch
switches between Standard Time and DST (summer time) automatically in
accordance with the received time signal.
•
The default DST setting is Auto DST (
AT
) whenever you select
LIS
,
LON
,
BCN
,
MAD
,
PAR
,
MIL
,
ROM
,
BER
,
STO
, or
ATH
as your Home City code.
•
If you experience problems receiving the time calibration signal in your area, it
probably is best to switch between Standard Time and Daylight Saving Time
(summer time) manually.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down
A
until the city code starts to flash, which
indicates the setting screen.
2. Press
B
and the DST setting screen appears.
3. Use
C
to cycle through the DST settings in the sequence shown below.
Auto DST (

4. When the setting you want is selected, press

The
