you hear Bluetooth MP3 music. So you can always maintain the preferred optimum volume level for each
audio source.
3.6 Using Internal/External Microphone
(factory default: internal microphone)
Users may use either the built-in microphone of the Bluetooth Mic (internal microphone) or the
microphone of a connected pair of headphones (external microphone). According to the application, you
may use either ones by using the switching operation. Press the (-) Button for 3 seconds and then the
mode will be switched to the one for internal microphone or external microphone.
3.7 Function Priority
The Bluetooth Mic operates in the following order of priority:
(highest) Mobile phone,
Intercom,
Music sharing by Bluetooth stereo music,
(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 an intercom conversation is interrupted by an incoming mobile phone
call.
3.8 Charging
The charging LED beside the charging port turns on red while charging and turns blue when the
Bluetooth Mic is fully charged. It takes about 2.5 hours to be completely charged. You can use the
Bluetooth Mic while charging. It is especially helpful when you use a cigarette charger for a long road trip.
