Solar Charging
Power generated by the solar panel powers
watch operations and also is used to charge a
rechargeable (secondary) battery. The solar
panel is integrated into the LCD of the watch,
and power for charging is generated
whenever the face is exposed to light.
Charging the Watch
●
When you are not wearing the watch, put it in
a location where it is exposed to bright light.
While you are wearing the watch, make sure
that its LCD (solar panel) is not blocked from
light by the sleeve of your clothing. Power
generation efficiency is reduced even when
the LCD is blocked only partially.

Important!
Depending on light intensity and local
●
conditions, the watch may become hot
to the touch when exposed to light for
charging. Take care to avoid burn
injury after charging. Also, avoid
charging the watch under high-
temperature conditions like the ones
described below.
On the dashboard of a vehicle
ー
parked in the sun
Near an incandescent light bulb or
ー
other source of heat

and charge the watch as soon as
possible after the battery indicator
shows
.
Charge the watch as soon as possible
●
after the battery indicator becomes
or lower. Leaving the watch
without charging for several months
results in over-discharge and may
make future charging impossible. If
this happens, contact your original
retailer.
Only the following functions are
●
available while the battery indicator
shows
: current time display,
stopwatch, timer, World Time, alarms.
Even when the battery indicator shows
●
, the current time can be
maintained by solar charging.
If the battery is dead and the watch
●
display is blank, use the charger cable
to charge the watch.
Regular charging at least once a month
●
is recommended to extend battery life,
even if you do not use the watch during
that time.
Note
Solar charging cannot charge the
●
battery up to level
.
