Bluetooth® Communication

The Bluetooth® interface can be used to transfer data to and from a Bluetooth® compatible printer.

Data can be transferred if the Handheld Terminal is located within three meters of the target device (and nothing is blocking the signal).

Important! Observe the following precautions to help ensure that Bluetooth communication is successful.

•Make sure the Handheld Terminal is visible from and within about 3 meters of the other Bluetooth® devices. The possible communication distance may be shorter depending on the surrounding environment (such as obstructions).

•Make sure there is at least two meters (6' 7") between the Handheld Termianal 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 3/4") 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.
