Caution: Observe the following precautions to help ensure that Bluetooth communication is

successful.

Make sure the terminal is visible from and within about 10 meters of the
other Bluetooth devices. The possible communication distance may be
shorter depending on the surrounding environment (such as
obstructions).

Make sure there is at least two meters (6’ 7”) between the terminal
and other equipment (electrical appliances, audio-visual equipment,
OA equipment, and digital cordless telephones, facsimile machines,
etc.) (Take special care with microwave ovens. Allow at lease three
meters (9’ 10 3/4”) between the terminal in wireless operation and a
microwave oven.) When approaching such a device when its power
is turned on, proper communication may prove impossible while this
may also cause interference with TV and radio reception (images
produced by certain UHF and broadcast satellite channels may
become blurry)

Normal communication may not be possible in an area near a
broadcast transmitter or wireless transmitter. If this happens, move
to a different location. Normal communication may not be possible
in areas exposed to strong radio waves.

RF Wireless LAN Interference
Because Bluetooth and RF wireless LAN use the same frequency
band (2.4GHz0, radio interference can occur if there is a wireless
LAN device nearby. This can result in lower communication speeds,
or even make it impossible to establish a connection. If this happens,
try the following countermeasures.

Move at least 10 meters (32’ 10 3/4”) away from the wireless LAN
device.

If you cannot keep the distance at least 10 meters (32’ 10 3/4”) or
more between the terminal and wireless LAN device, turn off the
power of either the terminal or the wireless LAN device.
