2. PRODUCT FEATURES OVERVIEW
Telephone interrupt pin
The cable on the Transceiver is equipped with a telephone interrupt pin (TEL INT). Such mechanism can be used to notify the car stereo unit to switch
mode when it detects incoming call and transferring call.
Automatic
Bluetooth
If the Transceiver is paired to both a
and Cradle for iPod®¹

profile switch
Clarion Bluetooth®Audio Transmitter
and a mobile phone, when there is an incoming call, a
stereo ringing tone will be heard and any music streaming will be temporarily
muted until call is ended or rejected.
Acoustic Echo Cancellation
Voice signals from the loudspeaker often appear at the microphone, this
causes conversational interference in the form of acoustic echo and howling.
With this advanced DSP-based Acoustic Echo Cancellation (AEC) system
built-in, it is capable of handling full-duplex communication, echo cancellation
and noise suppression on the microphone input to enable smooth handsfree
communication and crystal clear speech.
Separate volume control
There are two set of volume settings, one for handsfree mode and one
for music mode. This can ensure that the user can set the desired volume
for speech and music separately without having to change the volume when
picking up and ending call between music streaming.
Note:
