Bluetooth

Communication
Bluetooth
®
protocol can also be used to transfer data between two
Handheld Printer Terminals.
The two Handheld Printer Terminals should be no more than three
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 three meters (16'4
13 /
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 3
/
8
")
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
® 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 (32'10
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 Printer
Terminal and a Wireless LAN device, turn off the power of the Wireless LAN device.
