Watch Operation Guide 3501

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.
C
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
C
generation efficiency is reduced even when
the face of the watch is blocked only partially.
Alarm Mode
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
Under direct sunlight or in other hot
ー
areas for long periods
The display panel may become black
●
under very high temperatures. This is
temporary, and the display will return
to normal at lower temperatures.
YES NO
Low Battery
●
A low battery will cause [LOW] to flash and will
disable the functions below.
Time signal reception
●
Illumination
●
Sounds (alarm, etc.)
●
Connection with a phone
●
If the charge level drops even further, [CHG]
will flash. If this happens, all functions are
disabled.
Dead Battery
●
The digital display will go blank if the battery
goes dead. Memory data is lost, and watch
settings are returned to their initial factory
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. Keep the watch exposed
to light until the current time appears on
the display.
Note
If [R] is flashing, it means that all
●
functions, except for timekeeping, are
disabled due to high momentary
battery power consumption.
