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.
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).
ー
On the dashboard of a vehicle
parked in the sun
ー
Near incandescent lamps, camera
lights, halogen lamps, or other
sources of heat
ー
In locations exposed to direct
sunlight for long periods and other
hot locations
●
The display panel may become black
(or white, depending on the LCD type)
under very high temperatures. This is
temporary, and the display will return
to normal at lower temperatures.
●
Checking the Charge Level
A display indicator shows the watch’s current
charge level.
Charge Level 1: Good
All functions enabled.
Charge Level 2: Good
All functions enabled.
Charge Level 3: Low
[L] and [LOW] flash on the display and the
functions below become disabled.
●
Compass, altitude, barometric pressure/
temperature measurements
●
Face illumination
●
Sounds (alarm, etc.)
Charge Level 4: Low
When the battery charge drops lower than
Level 3, [CHG] starts to flash on the display
and all functions become disabled.
Charge Level 5: Dead
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.
Note
●
When [H], [M], and [L] are all flashing
on the display, it means that all
functions are disabled due to
momentary battery power
consumption.
l
[H], [M], and [L] are flashing on the
display.
