4 GB What is Bluetooth wireless technology? Bluetooth wireless technology is a short-range wireless technology that enables wireless data communication between digital devices, such as a computer or digital camera. Bluetooth wireless technology operates within a range of about 10 metres. 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, 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 standard is an international standard supported by thousands of companies all over the world, and employed by various companies worldwide. Communication System and Compatible Bluetooth Profiles of this unit Profile is standardization of the function for each Bluetooth device specification. This unit supports the following Bluetooth version and profiles: Communication System: Bluetooth Specification version 3.0 Compatible Bluetooth Profiles: A2DP (Advanced Audio Distribution Profile): Transmitting or receiving audio content of high-quality. AVRCP (Audio Video Remote Control Profile): Controlling A/V equipment; pausing, stopping, or starting playback, etc. HSP (Headset Profile)*: Talking on the phone/operating the phone. HFP (Hands-free Profile)*: Talking on the phone/operating the phone by hands-free. * When you use a Bluetooth mobile phone supported by both HFP (Hands-free Profile) and HSP (Headset Profile), set to HFP. Notes To be able to use the Bluetooth function, the Bluetooth device to be connected requires the same profile as the unit s. Note also that even if the same profile exists, devices may vary in function depending on their specifications. Due to the characteristic of Bluetooth wireless technology, the sound played on this unit is slightly delayed from the sound played on the Bluetooth device during talking on the telephone or listening to the music.
