Wireless Stereo Headset
What is BLUETOOTH technology?
BLUETOOTH wireless technology is a short-range wireless technology that enables wireless data
communication between digital devices, such as a mobile phone, computer, printer or digital camera.
BLUETOOTH wireless technology operates within a range of about 10 meters (about 30 feet).
Connecting two devices as necessary 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, nor 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.
Communication System and Compatible BLUETOOTH Profiles of this unit
Prole is standardization of the function for each BLUETOOTH device specication.
This unit supports the following BLUETOOTH version and proles:
Compatible BLUETOOTH Proles:
– A2DP (Advanced Audio Distribution Prole): Transmitting or receiving audio content of high-quality.
– AVRCP (Audio Video Remote Control Prole): Controlling A/V equipment; pausing, stopping,
playback, volume control, etc.
– HSP (Headset Prole)*: Talking on the phone/Operating the phone.
– HFP (Hands-free Prole)*: Talking on the phone/Operating the phone by hands-free.
* When you use a BLUETOOTH mobile phone supported by both HFP (Hands-free Prole) and
HSP (Headset Prole), set to HFP.
Note
In order to use the BLUETOOTH function, the BLUETOOTH device to be connected requires the
same prole as the unit’s.
Devices may vary in function depending on their specications even if the same prole exists.
