mended to always make a call from the main unit
as some phones may not work well using the
phoneʼs keypad with this unit.
Microphone
The unit is fitted with an internal microphone that
should provide acceptable performance when
fitted to vehicles with low levels of background
noise. For optimum performance Clarion recom-
mends the use of an external microphone fitted
as near as possible to the driver.
Please refer “Selecting microphone input” on
page 30 for switching to internal/external the mi-
crophone.
Handfree Volume
The unit implements an acoustic echo canceller
to reduce the echo heard by the remote caller.
Under normal circumstances the unit operates in
full-duplex mode meaning that both parties can
speak at the same time.
If the volume in the vehicle is set too high, the
echo canceller will revert to half-duplex mode
when only one party can talk at a time. The vol-
ume should be adjusted to be just loud enough.
The unit also implements Noise Dependent Vol-
ume that increases the volume as the noise in
the vehicle increases.

nience of dropping the call.
