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.
