Mode Hand and Day Indicator
Movement
Changing the day setting of the watch will also
cause the mode hand to move.
Day
It can take anywhere from about 15 to 30
seconds for the day indicator to change
after timekeeping reaches midnight. The
mode hand moves as the day indicator
changes.
The day indicator will not change while a
time measurement operation is in progress
in the Stopwatch Mode.
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.
NOYES
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).
