Fast Forward/Fast Reverse
After pulling out the crown, rotating it quickly
in succession in either direction will cause the
hands to move forward or back at high speed.
While the hands are moving forward at high
speed, quickly rotating the crown in
succession again will increase the speed even
further.
●
Stopping Fast Forward/Fast Reverse
Rotate the crown in the direction opposite that
of the ongoing operation or press any button.
Note
●
If you do not perform any operation
for about two minutes after pulling
out the crown, crown operations will
automatically become disabled. If
that happens, push the crown back
in and then pull it out again.
Hand and Day Indicator Movement
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.
●
Charging the Watch
When you are not wearing the watch, put it in
a location where it is exposed to bright light.
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.
●
Checking the Charge Level
Immediately after you press (C) to return to the
Timekeeping Mode, the day of the week hand
will indicate the battery charge level. After a
short while, the day of the week hand will
return to indicating the current day of the
week.
A
Good (high charge)
B
Good (medium charge)
C
Low Battery
●
Remaining Charge and Dead Battery
You can determine if the charge level is low by
checking the hand movement. Functions
become disabled as battery power goes low.
●
Day of the Week and Day Indicator
Operation
Changing the day setting of the watch will also
cause the day of the week hand to move in
conjunction with the day.
●
Day
●
It can take anywhere from about 10 to 40
seconds for the day indicator to change after
timekeeping reaches midnight. The day of
the week hand will move as the day indicator
changes.
●
The day may not be indicated correctly while
the watch’s crown is pulled out.
Important!
●
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
parked in the sun
—
Near an incandescent light bulb or
other source of heat
—
Under direct sunlight or in other
hot areas for long periods
Important!
●
Should battery go low or go dead,
expose the face (solar panel) to light
as soon as possible.
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.

Power Saving
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.
●
Recovering from Power Saving
Operation
Press any button or place the watch in a welllit area to recover from power saving.
Auto Time Adjustment
Your watch can receive time calibration
signals and connect with a phone to obtain
information that it uses to adjust its date and
time setting.
●
First Use of the Watch
Immediately after purchasing the watch, it will
acquire GPS location information and
configure a Home City based on your current
location.
Acquiring GPS Position Information
l
Manually
●
Normal Use of the Watch
Your watch automatically receives a time
calibration signal or GPS signal (time
information) regularly each day and adjusts its
time setting. This means its time setting is
always accurate without the need for any
adjustment by you.

information).
●
Auto receive of time calibration signal or
GPS signals (time information) starts to be
performed again after there is no connection
between the watch and a phone for more
than one day.
Note
●
If the watch is unable to adjust its
time setting automatically for some
reason, you can trigger a GPS signal

It can take as long as 13 minutes
when leap second information is
included.
●
You may experience location
information acquisition problems
when you are in the vicinity of a city
borderline.

●
Leap second information receive is
repeated until information receipt is
complete.
●
Once leap second information
receive is complete, the watch will
not make any attempt to receive it
again until the following June 1 or
December 1.
●
When connecting with a phone to
adjust the watch date and time
settings, leap seconds will also be
received along with the time
information. If this happens, leap
seconds may not be received when
receiving a GPS signal.
Note
●
Even if you are within the normal
reception range of a time calibration
signal, reception may be made
impossible by the following factors:
geographic contours, weather, the
season, the time of day, wireless
noise.

Auto Time Calibration Signal Receive
An automatic time calibration signal receive
operation is performed and the time and day
settings are adjusted between midnight and

successful, no more auto receive operations
are performed that day.
Getting ready
Enter the Timekeeping Mode.
Navigating Between Modes
l
Place the watch near a window or some other
location appropriate for signal reception.
●
The second hand points to “RC” while time
calibration reception in progress.
●
When the receive operation is successful,
the time and day settings will be adjusted
automatically.
Note
●
Reception takes anywhere from
about two minutes to about 10
minutes. It can take as long as 20
minutes.
Signal Reception Precautions
●
When the watch is unable to adjust its time
in accordance with a calibration signal for
some reason, average timekeeping
accuracy is within ±15 seconds per month.
●
Note that an internal decoding process the
watch performs after it receives a signal may
cause the time setting to be slightly off (by
less than one second).
●
GPS signal and time calibration signal
reception will not be possible under any of
the watch conditions described below.
—
While battery power is low
—
While the watch is in the Airplane Mode,
Stopwatch Mode, Timer Mode, or Alarm
Mode
—
When power saving is at Level 2 (GPS
signal reception also is not possible at
Level 1.)
—
While the crown is pulled out
—

If the receive operation is successful, the
time and day settings will be adjusted
automatically in accordance with the Home
City and summer time settings. Summer
time will not be applied correctly in the cases
described below.
—
When the summer time start date and
time, end date and time, or other rules are
changed by authorities

Mobile Link Precautions
●
Legal Precautions
●
This watch complies with or has received
approval under the radio laws of various
countries and geographical areas. Using
this watch in an area where it does not
comply with or has not received approval
under applicable radio laws may be a
criminal offense. For details, visit the CASIO
Website.
http://world.casio.com/ce/BLE/
●
Use of this watch inside of aircraft is
restricted under the aviation laws of each
country. Be sure to follow the instructions of
airline personnel.
●
Precautions when using Mobile Link
●
When using this watch in combination with
a phone, keep the watch and phone close
to each other. A range of two meters is
recommended as a guideline, but the local
environment (walls, furniture, etc.), the
structure of a building, and other factors may
require a much closer range.
●
This watch can be affected by other devices
(electrical devices, audio-visual equipment,
office equipment, etc.) In particular, it can be
affected by operation of a microwave oven.
The watch may not be able to communicate
normally with a phone if a microwave oven
is operating nearby. Conversely, this watch
may cause noise in radio reception and the
video image of a TV.
●
Bluetooth of this watch uses the same
frequency band (2.4 GHz) as wireless LAN
devices, and use of such devices in close
proximity of this watch may result in radio
interference, slower communication speeds
and noise for the watch and the wireless
LAN device, or even communication failure.

When in a hospital, on an aircraft, or in any
other area where the use of radio waves is not
allowed, use the operations below to stop
radio wave generation.
●
