Bluetooth TM Communication
Bluetooth TM protocol can also be used to transfer data between two Handheld Terminals.
With Bluetooth TM , the two Handheld Terminals should be located within about five
meters (19 11 ⁄
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 Bluetooth TM devices are located within five meters (19 11 11 11 11 11 ⁄⁄⁄⁄⁄
16 16 16 16 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' 10
3 33 33 ⁄⁄⁄⁄⁄
8 88 88
" ) 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 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 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.
• Set the Wireless LAN mode of the Handheld Terminal to off (DT-X5M10R/DT-
X5M10UR/DT-X5M30R/DT-X5M30UR).
