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.
