4. INTRODUCTION TO BLUETOOTH® “PAIRING”

What is Bluetooth® wireless technology?

Bluetooth® wireless technology is a radio technology that connects devices, such as mobile phones and headsets, without wires or cords over a short distance of approximately 10 meters (approx. 33 feet). Get more information at www/bluetooth.com.

What is Bluetooth® wireless profiles?

Bluetooth® wireless profiles are the different ways that Bluetooth® devices communicate with other devices. Bluetooth® phones support either the headset profile (HSP), the hands-free profile (HFP) or both. In order to support a certain of profiles, a phone manufacturer must implement certain mandatory features within the phone's software. The Bluetooth® Audio/Mobile-phone Transceiver unit supports both HSP and HFP profiles. In addition, it also supports A2DP and AVRCP in order to allow music streaming and playback control. Please refer chapter "Music Streaming andPlayback Control" on page 19 for more description on these profiles.

What is pairing?

With a mobile phone featuring Bluetooth® technology, you must “pair” the Transceiver unit with the phone/Bluetooth® Audio Transmitter before you use it for the first time.

"Pairing" creates a unique wireless link between the phone/Bluetooth® Audio Transmitter with Bluetooth® wireless technology and your Bluetooth® Audio/ Mobile-phone Transceiver unit eliminating the need to repeat the pairing process during future use. Bluetooth® devices will not work if the devices have not been paired.

What is passkey?

Passkey or PIN is a code that you enter on your mobile phone to pair it with the Transceiver unit. This makes your phone and the Transceiver unit recognize each other and automatically work together.
