• Automatic

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.

1. The Transceiver will establish an automatic connection in the following situations:

• After a previously successful connection, and the Transceiver is switched on again, it will automatically try to re-connect with the last paired mobile phone (Depends on multiple re-connection mode). Connection may take up to a minute depending on the mobile phone.

• Some mobile phones will require user confirmation for connection. In such case, user will need to acknowledge the connection on the mobile phone before the connection is re-established.

2. The Transceiver will not establish an automatic connection or fail to connect in the following situations:

• If the mobile phone already has connection with other handsfree/ headset

• If the paired mobile phone is powered off and on (depends on mobile phone)

• If the paired mobile phone is out of range

• If the paired mobile phone is powered on after the Transceiver is turned on where multiple re-connection mode set to off.

In such cases, the user will need to manually re-connect to the Transceiver through the mobile phone.
