Bluetooth® interface can also be used to transfer data between two Handheld Terminals. With Bluetooth® the two Handheld Terminals should be located within about three meters (9'10ε") from each other, as long as there is nothing blocking the path between them.
Important!
Observe the following precautions to help ensure that Bluetooth communication is successful.
ξMake sure two Handheld Terminals face each other within three meters (9'10ε").
Surroundings (obstacles) between the Handheld Terminals may cause a shorter distance.
ξMake sure there is at least two meters (6'7") between the Handheld Terminal and other equipment (electrical appliances,
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).
ξNormal communication may not be possible in an area near a broadcast trans- mitter or wireless transmitter. If this happens, move the Handheld Terminal to a different location. Normal communication may not be possible in areas exposed to strong radio waves.
ξRF 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.
ξMove at least 10 meters (32'10ε") away from the wireless LAN device.
ξIf you cannot keep the distance at least 10 meters (32'10ε") 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.
ξAlthough the Handheld Terminal enables wireless LAN and Bluetooth® communication to be used simultaneously as a result of being equipped with Bluetooth® Ver.2.0, communication may not be possible depending on the surrounding radio wave environment.
