stable movement of the
watch.

ENERGY DEPLETION FOREWARNING FUNCTION

When the energy stored in the rechargeable battery is reduced to an extremely
l
low level, the second hand starts moving at 2-second intervals instead of the
normal 1-second intervals. The watch remains accurate even while the second
hand is moving at 2-second intervals.
When this occurs, recharge the watch as soon as possible by exposing it to light.
l
Otherwise, the watch switches to five-second interval movement, followed by a
completely stopped state.
•
Neither the buttons nor the crown can be operated while the second hand moves at two-
second or five-second intervals (this is not a malfunction).
•
While the second hand moves at five-second intervals, the hour and minute hands, and date
stop operating.
•
While the second hand moves at five-second intervals, the watch is unable to receive radio
signals automatically. After the watch is charged sufficiently and the second hand returns to
normal one-second interval movement, conduct the manual reception of radio signals to set
the watch to the correct time.
TO PREVENT THE ENERGY DEPLETION
v
•
When wearing the watch, make sure that the watch is not covered by
clothing.
•
When the watch is not in use, leave it in a bright place as long as
possible.
