Bluetooth
TM
Data Communication (IT-500M30B/M30CB)
Bluetooth
TM
protocol can also be used to transfer data between two Handheld
Terminals.
With Bluetooth
TM
the two Handheld Terminals should be located within about three
meters (9
'10
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 data communication is
successful.
•
Make sure the Bluetooth
TM
devices are located within three meters (9
'10
3
⁄
8
"
) of
each other. Surroundings (obstacles) may require a shorter distance between the
two devices.
•
Make sure there is at least two meters (6' 7") between this device and other
devices (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
3
⁄
8
) between communicating
devices and a microwave oven.) When approaching such a device when its
power is turned on, proper data 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 data communication may not be possible in an area near a broadcast
transmitter or wireless transmitter. If this happens, move to a different location.
Normal data communication may not be possible in areas exposed to strong
radio waves.
•
RF Wireless LAN Interference
Because Bluetooth
TM
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 data 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.
•
Set the RF wireless LAN mode of the Handheld Terminal to off.
