Charging - Casio 5724 Operation Manual

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
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!
Some light sources and environments
●
can cause the watch to become
extremely hot during charging, which
creates the risk of burn injury and
damage to internal watch
components.
Avoid charging the watch under
conditions like the ones described
below, where the temperatures may
exceed 60 °C (140 °F).
On the dashboard of a vehicle
ー

defaults.
Important!
Should the battery go low or go dead,
●
expose the face (solar panel) to light as
soon as possible.
Exposing the watch to light while its

battery is dead will cause [CHG] to
start flashing. Expose the watch to light
to charge it until the Timekeeping
Mode screen re-appears.
Note
If [R] is flashing, it means that all
●
functions, except for timekeeping, are
disabled due to high momentary
battery power consumption.
