Bluetooth

Communication

Bluetooth

interface can also be used to transfer data between two Handheld Terminals.

With Bluetooth

the two Handheld Terminals should be located within about three meters

'10



) from each other, as long as there is nothing blocking the path between them.

Important!

Observe the following precautions to help ensure that Bluetooth communication is

successful.

Make sure two Handheld Terminals face each other within three meters (9

'10





Surroundings (obstacles) between the Handheld Terminals may cause a shorter

distance.

Make sure there is at least two meters (6'7") between the Handheld 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 least three meters (9'10





) between the Handheld

Terminals 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 trans-

mitter or wireless transmitter. If this happens, move the Handheld Terminal 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

(2.4GHz), 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





) away from the wireless LAN device.

If you cannot keep the distance at least 10 meters (32

'10





) or more between the

Handheld Terminal and a wireless LAN device, turn off the power of either the

Handheld Terminal or the wireless LAN device.

Although the Handheld Terminal enables wireless LAN and Bluetooth

communication to be used simultaneously as a result of being equipped with

Bluetooth

Ver.2.0, communication may not be possible depending on the

surrounding radio wave environment.
