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.
NOYES
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

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.
●Safety Precautions
ZWARNING Wireless
●Inside of a medical facility or on an aircraft,
be sure to follow the instructions of persons
in charge concerning the use of radio wave
emitting devices. Electromagnetism
emitted by the watch may affect
instrumentation, which creates the risk of
accident.
●Do not use this watch in the vicinity of high-
precision electronic equipment or electronic
equipment that handles weak signals.
Doing so can cause operational or other
problems with the electronic equipment,
which creates the risk of accident.
●People who are fitted with a pacemaker
should keep this watch away from their
chest area. Magnetism can affect the
operation of pacemakers and other medical
devices. Should you ever start to feel any
abnormality, immediately move the watch
away from you and consult a physician
●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.
●Stopping Radio Wave Emission by This
Watch
The watch is emitting radio waves whenever
e is flashing or displayed.
In addition, the watch also connects phone
automatically four times a day to adjust its time
setting.
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.
●Stopping Radio Wave Generation
Press any button to terminate the Bluetooth
connection.
Connected After disconnection
●Disabling Auto Time Adjustment
Configure G-SHOCK Connected settings to
disable time adjustment between the watch
and phone.

Troubleshooting
Signal Reception (Time
Calibration Signal)
Q1 The watch cannot perform a receive
operation.
Is the watch’s battery charged?
Signal reception is not possible while
battery power is low. Keep the watch
exposed to light until it recharges
sufficiently.
lSolar Charging
Is the watch in the Timekeeping Mode?
Time signal receive is performed only
while the watch is in the Timekeeping
Mode. Return to the Timekeeping Mode.
lNavigating Between Modes
Is your Home City setting correct for your
location?
The watch will not indicate the correct time
if the Home City setting is wrong. Change
your Home City setting so it correctly
reflects your location.
lSetting a Home Time City
Is the watch connected with a phone?
Auto receive of signals by the watch is
disabled while it is connected with a
phone.
lTime Adjustment Using a Time Signal
After checking the above, the watch still
cannot perform a receive operation.
Time calibration signal reception is not
possible under the conditions described
below.
●When watch is at Level 2 power saving
●Timer countdown operation in progress
If successful reception is not possible for
some reason, you can adjust the time and
day settings manually.
Q2 The signal receive operation always
fails.
Is the watch in a location that is appropriate
for signal reception?
Check your surroundings and move the
watch to a location where signal reception
is better.
lAppropriate Signal Reception Location
Did you avoid touching the watch while the
receive operation was in progress?
Minimize movement of the watch and do
not perform any watch operation while a
receive operation is in progress.
Is there an alarm configured to sound
during the same period that the signal
receive operation is performed?
Receive stops if an alarm operation starts
while it is being performed. Disable the
alarm.
lEnabling/Disabling an Alarm or the
Hourly Time Signal
Is the signal transmitter in your area
transmitting a signal?
The transmitter of the time calibration may
not be transmitting a signal.
Try again later.
Q3 Signal reception should have been
successful, but the watch’s time and/
or day is wrong.
Adjust time and day settings manually.
lAdjusting Time Settings Manually
I can’t pair the watch with a
phone.
Q1 I’ve never been able to establish a
(pairing) connection between the
