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.
