Day indicator
●It can take anywhere from about 10 to 40
seconds for the day indicator to change
after timekeeping reaches midnight.
●The day may not be indicated correctly
while the watch’s crown is pulled out.
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

●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 [C].
Even if the second hand is not pointing at [C],
the watch will automatically attempt to
connect with a phone four times a day to adjust
its time settings.
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.
