Using the Crown
Depending on the operation you want to
perform, pull out the crown to the first or
second click and then rotate it.
Important!
●
To prevent loss of water resistance
and/or damage due to impact, be

succession in either direction will start a fast
in
forward or fast reverse operation. While a fast
forward operation is in progress, quickly
rotating the crown in succession again will
increase the speed even further.
●
The fast reverse operation speed is fixed
and cannot be changed.
●
Stopping Fast Forward/Fast Reverse
Rotate the crown in the direction opposite that
of the ongoing operation or press any button.

Solar Charging
What is solar 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.
●
This watch uses a special rechargeable
(secondary) battery.
ー
The watch’s battery will not charge if the
watch’s temperature is less than
approximately -10°C (14°F) or greater
than approximately 60°C (140°F).
ー
Over-discharge will occur if the watch is
not charged within approximately three
months after it stops operation due to low
battery power. Charging may not be
possible after over-discharge occurs.
Charging the Watch
When you are not wearing the watch, put it in
a location where it is exposed to bright light.
Important!
●
If the second hand stops for some
time after the watch is continuously
exposed to light, it could mean that
charging
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.

Charge Level 2 :
Time from hand movement starts until a full

Note
●
charging time depends on the
Actual
local charging environment.
Checking the Charge Level
The charge level is indicated by watch hand
movement. Functions become disabled as
battery power goes low.
While you are wearing the watch, make sure
that its face (solar panel) is not blocked from
the
light by the sleeve of your clothing. Power
generation efficiency is reduced even when
the face of the watch is blocked only partially.
Note
●
Exposing
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

The watch’s time, day, and Home City (time
zone) settings can be configured in
accordance with a received GPS signal or
time calibration signal.
●
GPS signal position information: Used to
update Home City (time zone), time, and
day settings.

Time Adjustment Using GPS
Appropriate Signal Reception
Location
GPS signal reception is possible outdoors
where the sky is visible and not blocked by
buildings, trees, or other objects.

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.
●
Before trying to receive GPS signal
time information and/or a time
calibration signal, first use GPS to
acquire position information and
configure Home Time (time zone)
settings.
●
the watch into the Airplane Mode

Release
the button as soon as the second
hand points to “T+P”.
●
The second hand will move in the
following sequence:
“Y(YES)” or
“N(NO)” n “T (TIME)” n “T+P”.
●
This indicates that position information
acquisition has started.
Note
●
Reception takes anywhere from
about 30 seconds to about two
minutes.

The watch’s time and day will not be
indicated correctly if the Home City
(Time Zone) setting is not right for
your location. Perform position
information acquisition in a
representative city in your time zone
or in a location that is well within the
time zone. Or you can perform a time
information receive operation to
adjust time and day settings after
configuring Home City (Time Zone)
and summer time settings manually.
