3.11 Sound Volume Adjusting on BTA
Only if BTA with Remote control unit, BTA could achieve volume adjusting
function. Sound volume adjusting of HFP Bluetooth phone call and sound volume
adjusting of A2DP music play, they are independent of each other. Sound volume
setting will be saved automatically after adjusted, which is only valid for current
mobile phone. If changing another mobile phone, sound volume setting has to be
adjusted again. Detail setting methods as follows:
HFP Bluetooth hands free sound volume adjusting: When BTA is under HFP
Bluetooth hands free phone call status, press both Previous Track button and
Answer/Hang up button on remote control unit for once, and the sound volume of
HFP Bluetooth phone call will decrease a level with warning tone on some mobile
phones. When the sound volume is adjusted to lowest level, there will also be
warning tone of lowest sound level. Press both Next Track button and Answer/Hang
up button on remote control unit for once, and the sound volume of HFP Bluetooth
phone call will increase a level with warning tone on some mobile phones. When the
sound volume is adjusted to highest level, there will also be warning tone of highest
sound level.
A2DP music playback sound volume adjusting: When BTA is under A2DP music
playback status, the operation of A2DP music playback sound volume adjusting and
the warning tones of the operation are same as that of HFP Bluetooth hands free
sound volume adjusting.
Generally, we do not advice that you adjust the sound volume to highest level,
which will cause volume distortion.
3.12 Paired Devices List Clearing
BTA can support up to two mobile phones or other devices, and recently paired
devices will be saved on BTA's pairing list. When turned on, BTA will automatically
try to connect the last two connected Bluetooth devices for your use convenience.

stuck when BTA turns on.
Hold both Previous Track button and Next Track button on remote control unit for
5 seconds, all the paired devices on BTA's list will be cleared, and now BTA enters
pairing status. Once Pairing list is cleared, it can not be resumed; you need to pair
with device again before using it. Pairing list can only be cleared by Remote Control
buttons.
