Bluetooth

protocol can also be used to
transfer data between two Handheld
Printer Terminals.
The two Handheld Printer Terminals
should be no more than five meters apart
(as long as there is nothing blocking the
path in between).
Important!
Observe the following precautions to help ensure that data communication is
successful.
•
Make sure that the Handheld Printer Terminal are located within about five
meters (16

) of each other. Surroundings (obstacles) may require a shorter
distance between the two terminals.
•
Make sure there is at least two meters (6' 7") between this device and other
devices (electrical appliances, audio-visual equipment, office automation
equipment, and digital cordless telephones, facsimile machines, etc. Take special
care with microwave ovens. Allow at least three meters (9' 10

"
) between
communicating devices and a microwave oven.) When approaching such a
device with 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.
•
Wireless LAN Interference
Because Bluetooth
TM
and 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

⁄

) away from the Wireless LAN device.
•
If you cannot keep the distance at least 10 meters (32

) or more between the
Handheld Printer Terminal and a Wireless LAN device, turn off the power of the
Wireless LAN device.
