Solar Charging
What is solar charging?
This watch runs on power supplied from a
rechargeable (secondary) battery that is
charged by a solar panel. The solar panel is
integrated into the face of the watch, and
power is generated whenever the face is
exposed to light.
●
This watch uses a special rechargeable
(secondary) battery.
ー
The watch’s battery will not charge if the
watch’s temperature is less than
approximately -10°C (14°F) or greater
than approximately 60°C (140°F).
ー
Over-discharge will occur if the watch is
not charged within approximately three
months after it stops operation due to low
battery power. Charging may not be
possible after over-discharge occurs.
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 face (solar panel) is not blocked from
the light by the sleeve of your clothing. Power
generation efficiency is reduced even when
the face of the watch is blocked only partially.
NO
YES
Important!
●
If the second hand stops for some
time after the watch is continuously
exposed to light, it could mean that
charging is not possible due to over-
discharge. Request chargeable
(secondary) battery replacement by
your original retailer or authorized
CASIO service center.
●
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.
ー
On the dashboard of a vehicle
parked in the sun
ー
Near an incandescent light bulb or
other source of heat
ー
Under direct sunlight or in other
hot areas for long periods
Note
●
Exposing the watch face to light after
the battery goes dead will cause the
second hand to revolve
counterclockwise until it stops at
second 57. This indicates charging
has started.
●
A fully charged watch can operate
for approximately seven months
without further charging. Watch
operation will stop approximately 20
days after the battery goes low.

Charge Level 1 :
Time from dead battery until hand movement
starts
Charge Level 2 :
Time from hand movement starts until a full
charge
Note
●
Actual charging time depends on the
local charging environment.
Checking the Charge Level
The charge level is indicated by watch hand
movement. Functions become disabled as
battery power goes low.
Important!
●
Should battery go low or go dead,
expose the face (solar panel) to light
as soon as possible.
Immediately after pressing (C) to enter to the
Timekeeping Mode, the second hand will
move to one of the positions below to indicate
the battery charge level.
