Bluetooth

Communication
Bluetooth
®
interface can also be used to transfer data between two terminals.
With Bluetooth
®
the two terminals should be located within about fi ve meters 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.
• Make sure two terminals face each other within fi ve meters. Surroundings
(obstacles) between the terminals may cause a shorter distance.
• Make sure there is at least two meters between the terminal 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 between the terminals in wireless operation and a
microwave oven. When operating the terminal in Bluetooth nearby these devices
and electrical appliances with their powers being turned on, communication may
be interrupted or radio receptions may be interfered.
• Normal communication may not be possible in an area near a broadcast
trans-mitter or wireless transmitter. If this happens, move the terminal to a
diff erent location. Normal communication may not be possible in areas exposed to
strong radio waves.
• Interference by WLAN
Because Bluetooth
®
and WLAN use the same frequency band (2.4GHz), radio
interference can occur if there is a WLAN device nearby. This can result in lower
communication speed, or even make it impossible to establish a connection. If this
happens, try the following countermeasures.
• Move at least 10 meters away from the WLAN device.
• If you cannot keep the distance at least 10 meters or more between the terminal and a
WLAN device, turn off the power of either the terminal or the WLAN device.
• If the terminal’s wireless LAN and Bluetooth
®
communication are used at the same
time, ambient radio signals may make communication impossible.
