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
(9

3
⁄
8
") 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

"). 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
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
(2.4GHz), 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
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
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. 1.2, communication may not be possible depending on the
surrounding radio wave environment.
