Cautions for Operating
This unit is a precision device. Please be aware of the following to operate correctly.
• Avoid direct rays and heating equipments nearby.
• Avoid places of extremely high or low temperature, or where the temperature change greatly.
• Avoid strong impact and vibration, or places with strong impact and vibration.
• Avoid humid and dusty places.
For Good Communication
Normal operation may not be possible depending on environment. Please be aware of the following
points when setting up the LifeBook.
• The LifeBook and Bluetooth
TM
, as connecting partners, should be set-up within 50m. Connecting
distance may be shortened depending on surrounding environment (such as wall and furniture)
and structure of building.
Especially for building using ferroconcrete, when set-up either side of a wall such as up and down
stairs or two different rooms, communication may not be possible.
• Set-up the LifeBook apart from other units (such as electric machinery, AV units, OA units, digital
cord-less telephone and fax) more than 2m (more than 3m from microwaves, as it’s affected by
microwaves when microwave is in use). Setting-up near those units may cause noise or reception
obstacles on TV and radio (screening disorder may occur on particular channels of UHF and
satellite broadcasting).
• When broadcasting station or wire-less apparatus is nearby, and not being able to have normal
communication, please adjust antenna of the unit or relocate the LifeBook. Normal communication
may be interrupted when surrounding radio waves are strong.
• Radio Wave Interference with Wireless LAN
As both Bluetooth
TM
and Wireless LAN use the same frequency band (2.4 GHz), radio wave
interference may be occurred to slow the correspondence or connecting infeasibility, when using
near the LifeBook. In such cases, please take the following action.
– Separate Wireless LAN and the LifeBook more than 10m.
– When using within 10m, either the Wireless LAN or LifeBook should be turned off.
