Eff ective communication range
BLUETOOTH devices should be used within
approximately 10 meters (unobstructed
distance) of each other. Th e eff ective
communication range may become shorter
under the following conditions.
– When a person, metal object, wall or other
obstruction is between the devices with a
BLUETOOTH connection
– Locations where a wireless LAN is installed
– Around microwave ovens that are in use
– Locations where other electromagnetic waves
occur
Eff ects of other devices
BLUETOOTH devices and wireless LAN
(IEEE 802.11b/g) use the same frequency band
(2.4 GHz). When using your BLUETOOTH
device near a device with wireless LAN
capability, electromagnetic interference may
occur. Th is could result in lower data transfer
rates, noise, or inability to connect. If this
happens, try the following remedies:
– Try connecting this system and
BLUETOOTH mobile phone or
BLUETOOTH device when you are at least
10 meters away from the wireless LAN
equipment.
– Turn off the power to the wireless LAN
equipment when using your BLUETOOTH
device within 10 meters.
Eff ects on other devices
Th e radio waves broadcast by this system may
interfere with the operation of some medical
devices. Since this interference may result in
malfunction, always turn off the power on
this system, BLUETOOTH mobile phone
and BLUETOOTH device in the following
locations:
– In hospitals, on trains, in airplanes, at gas
stations, and any place where fl ammable
gasses may be present
– Near automatic doors or fi re alarms
