Charging Times; Checking The Charge Level; Power Saving Function - Casio 5454 Operation Manual

Important!
If the second hand stops for some
●
time after the watch is continuously
exposed to light, it could mean that
charging is not possible due to over-
discharge. Request chargeable
(secondary) battery replacement by
your original retailer or authorized
CASIO service center.
Depending on light intensity and
●
local conditions, the watch may
become hot to the touch when
exposed to light for charging. Take
care to avoid burn injury after
charging. Also, avoid charging the
watch under high-temperature
conditions like the ones described
below.
On the dashboard of a vehicle
ー
parked in the sun
Near an incandescent light bulb or
ー
other source of heat
Under direct sunlight or in other
ー
hot areas for long periods
Note
Exposing the watch face to light after
●
the battery goes dead will cause the
second hand to revolve
counterclockwise until it stops at
second 57. This indicates charging
has started.
A fully charged watch can operate
●
for approximately seven months
without further charging. Watch
operation will stop approximately 20
days after the battery goes low.

Power Saving Function

Leaving the watch in a dark location for about
one hour between the hours of 10 p.m. and 6
a.m. will cause the second hand to stop, and
the watch will enter Level 1 power saving. If
the watch is left in this condition for six or
seven days, all hands will stop and the watch
will enter Level 2 power saving.
Level 1:
Basic timekeeping functions are operational.
Level 2:
Only the day indicator is operational.
Note
Note that the watch also may enter
●
the power saving state if its face is
blocked from light by your sleeve
while you are wearing it.
The watch will enter power saving
●
from the Timekeeping Mode only.
