Telephone mute function (Tel)
If a telephone with hands-free operation is installed, the call
may be routed through the speaker system. This eliminates
the need for an additional speaker. However, the signal leads
(AF – Telephone input and Earth – Telephone input) must be
connected to the car radio (see page 83).
To set, call up user menu. Press the multifunction but-
ton to choose between
Audio Sig. (audio signal) and Mute.
Mute - Telephone mute setting
Audio Sig. - Telephone conversation via car radio
LED setting
This function can be used to switch the LED function (flashes

Setting reception optimisation (M/S)
In order to suppress reception-related interference, three dif-
ferent parameters can be set for reception optimisation.
Call up user menu. Press the multifunction button to
select
Stereo, Mono or Auto.
Auto: Setting for normal operation - i.e. the unit switches
from stereo to mono reception and back, depending on the
reception conditions (for nearly all reception areas, this is
the optimal setting).
