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
Checking the Charge Level
In the Timekeeping Mode, the current charge
level is indicated by the mode hand.
A Good (high charge)
B Good (medium charge)
C Low Battery
Low Battery
A low battery will cause [LOW] to flash and will
disable the functions below.
Illumination
Sounds (alarm, etc.)
Connection with a phone
If the charge level drops even further, [CHG]
will flash and the hour and minute hands will
stop at 12 o’clock. 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. 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.
