Function Priority
The SPH10 operates in the following order of priority:
(highest) Mobile phone,
Intercom,
Stereo music by audio cable, and
(lowest) Bluetooth stereo music
A lower priority function is always interrupted by a higher priority function. For example, stereo
music is interrupted by intercom call, and intercom conversation is interrupted by incoming
mobile phone call.
Tip: Stereo Music by Bluetooth or 3.5mm audio cable
Bluetooth music is available only when the MP3 jack port remains open. Please make sure
the audio cable is unplugged from the clamp unit to play music by Bluetooth.
