Solar Charging - Casio 5526 Operation Manual

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.
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.
YES NO
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

Remaining Charge and Dead Battery
●
You can determine if the charge level is low by
checking the 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.
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.
Low Battery Power
The second hand jumps at two-second
intervals.

Dead Battery
All hands and the day indicator are stopped.

Leaving the watch in a dark location for about
one hour between the hours of 10 p.m. and
5:50 a.m. will cause the second hand to stop,
and the watch to enter Level 1 power saving.
If the watch is left in this condition for six or
seven days, all hands will stop and the watch
will enter Level 2 power saving.
Level 1 :
Basic timekeeping functions are operational.

●
the power saving state if its face is
blocked from light by your sleeve
