B. Insufficient Charge Warning Function
The second hand changes from 1-second interval movement to
2-second interval movement to indicate that the watch has
become insufficiently charged. After about 2 days or more
have passed since the start of two-second interval movement
without light shining onto the watch, the watch stops
as a result of being insufficiently charged.
[Note] During two-second interval movement, regular automatic and free reception are
not available, and the time cannot be corrected manually.
ā
If the watch becomes insufficiently charged while radio wave reception, confirmation of
reception result, time difference correction or checking or setting the reference position is in
progress, the operation is interrupted and the watch returns to the time prior to the operation
being performed. The watch begins 2-second interval movement at this time. Try to keep
the watch charged at all times to prevent it from becoming insufficiently charged.
C. Overcharging Prevention Function
This function eliminates any worry regarding effects on the rechargeable
cell, timekeeping accuracy, performance or functions of the watch no
matter how much the watch is charged.
When the rechargeable cell becomes fully charged by exposing the solar cell to light, the
overcharging prevention function is activated automatically to prevent the battery from
being charged further.
