BluetoothTM Communication

BluetoothTM protocol can also be used to transfer data between two Handheld Terminals. With BluetoothTM, the two Handheld Terminals should be located within about five meters (1911⁄16") from each other, as long as there is nothing blocking the path between them.

Important!

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

•Make sure the BluetoothTM devices are located within five meters (1911⁄16") of each other. The particular 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' 103⁄8") between communicating devices 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.

•Wireless LAN Interference

Because BluetoothTM 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 communication speeds, or even make it impossible to establish a connection. If this happens, try the following countermeasures.

•Move at least 10 meters (32'103⁄4") away from the Wireless LAN device.

•If you cannot keep the distance at least 10 meters (32'103⁄4") 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 Wireless LAN mode of the Handheld Terminal to off (DT-X5M10R/DT-

X5M10UR/DT-X5M30R/DT-X5M30UR).
