About Bluetooth function
What is Bluetooth technology?
• Bluetooth wireless technology is a short-range
wireless technology that enables wireless data
communication between digital devices, such as a
cellular phone and a headset. Bluetooth wireless
technology operates within a range of about 10 m
(about 33 feet). Connecting two devices is
common, but some devices can be connected to
multiple devices at the same time.
• You do not need to use a cable for connection
since Bluetooth technology is a wireless
technology, neither is it necessary for the devices
to face one another, such is the case with infrared
technology. For example, you can use such a
device in a bag or pocket.
• Bluetooth technology is an international standard
supported by millions of companies all over the
world, and employed by various companies
worldwide.
On Bluetooth communication
• Bluetooth wireless technology operates within a
range of about 10 m.
Maximum communication range may vary
depending on obstacles (person, metal, wall, etc.)
or electromagnetic environment.
• The following conditions may affect the
sensitivity of Bluetooth communication.
– There is an obstacle such as a person, metal, or
wall between this unit and Bluetooth device.
– A device using 2.4 GHz frequency, such as a
wireless LAN device, cordless telephone, or
microwave oven, is in use near this unit.
• Because Bluetooth devices and wireless LAN
(IEEE802.11b/g) use the same frequency,
microwave interference may occur and result in
communication speed deterioration, noise, or
invalid connection if this unit is used near a
wireless LAN device. In such as case, perform the
following.
– Use this unit at least 10 m away from the
wireless LAN device.
– If this unit is used within 10 m of a wireless
LAN device, turn off the wireless LAN device.
– Install this unit and Bluetooth device as near to
each other as possible.
