User Interface

2.1 Buttons

The headset is equipped with a user interface including three buttons, referred to as VOL+, VOL-, and BT (Bluetooth). On the silk print of the Development Kit PCB, these buttons are designated +, -, and FUNC1 respectively. FUNC2 is never used.

The BT button is mainly used for connection management, including connection transfer1, as well as muting the headset microphone. When an audio connection is present, the VOL+ and VOL- buttons are used for adjusting the headset speaker volume. In Config. mode, these buttons adjust the indication volume. When no connection exists, the BT button is used for initiating an outgoing connection to one of the paired AGs. Either of the VOL+ and VOL- buttons initiates a connection to the other paired AG.

Pressing one of the buttons when powering up the headset enters Config. mode. In this mode, the headset will require authentication. When successfully paired, the BD address and link key will be stored in one of two available AG slots. The AG slot to update is selected by the button pressed at power-up: Pressing the BT button selects slot #1, whereas pressing one of the VOL+ and VOL- buttons selects slot #2. A successful pairing automatically exits Config. mode, or it may be done manually by pressing the BT button.

Table 2-1provides an overview of the way the button actions depend on the system mode.

1.Connection transfer is used to request the audio output endpoint to be moved from the phone/handset to the headset. In terms of Bluetooth connectivity, this involves requesting a Bluetooth link (ACL&SCO) between phone and headset.
