3S
Low Battery Warning
When the battery is low, the blinking blue LED in stand-by mode turns to
red and you will hear mid-tone triple beeps and a voice prompt saying
"Low battery".
Adjusting the Volume Level
You can easily adjust the volume by pressing the (+) Button or the (-)
Button. You will hear a beep when the volume reaches maximum or
minimum level. The volume is set and maintained independently at
different levels for each audio source even when you turn off and on
the headset. For example, once you set the volume for mobile phone
handsfree, it will not change even if you adjust the volume when you
hear Bluetooth MP3 music. So you can always maintain the preferred
optimum volume level for each audio source.

Function Priority
The 3S operates in the following order of priority:
(Highest)
Mobile Phone
Intercom
(Lowest)
Bluetooth Stereo Music
A lower priority function is always interrupted by a higher priority
function. For example, stereo music is interrupted by an intercom call,
and intercom conversation is interrupted by an incoming mobile phone
call.
Fault Reset
When the 3S is not working properly or is in faulty status for any reason,
you may reset by pushing the pin-hole reset button on the left speaker
unit. Insert a paper clip into the reset pin-hole and press and hold the
reset button for a second with light pressure. The 3S will be switched
off after which time, you have to turn the system back on and try again.
However, this will not restore the headset to factory default settings.
