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.
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.
ーOn the dashboard of a vehicle
parked in the sun
ーNear an incandescent light bulb or
other source of heat
ー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.
●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
the second hand is pointing to e (Bluetooth
connected) or R (Bluetooth connection
standby). Even if the second hand is not
pointing at e or “R”, the watch will attempt to
connect with a phone once a day to update its
time settings.
When in a hospital, on an aircraft, or in any
other area where the use of radio waves is not
allowed, hold down the watch’s (D) button for
about five seconds to enter the Airplane
Mode.
