DNC

Dynamic Noise Covering

With DNC, a volume considered to be pleas-

ant when the vehicle is stationary is boost-

ed during driving.

Depending upon noise development in the

car, the frequency ranges are boosted with

different intensity.

Even during changing noise development,

the volume and the sound pattern remain

pleasantly distinguishable. Short-term noi-

ses such as, for example, when crossing

railway tracks, are not taken into account.

DNC calibration

For operation in your particular car, you have

to calibrate using the test microphone. With

the adhesive tape supplied, the microphone

is fixed permanently in the vicinity of the

console, but not directly in the most droning

positions or close to the ventilation/heating.

The microphone opening must be directed

towards the passanger compartment. Cali-

bration should be performed in a quiet place

with the engine off.

• Press DSA until “DNC-MID”, “DNC-

HIGH”, “DNC-LOW” or “DNC-OFF” ap-

pears.

• Press any preset button (1-6) for ap-

prox. 2 seconds until “MicPos 8” ap-

pears in the display.

DNC calibration is now in operation and

functioning automatically.

The display indicates “DNC-ADJ”, now ac-

tual calibration is taking place. Once “DNC-

OK” appears in the display, calibration is

complete. The display indicates “DNC-MID”

for approx. 8 seconds.

Programming the DNC sensitivi-

ty

Volume boosting can be selected on three

levels:

DNC-LOW, DNC-MID, DNC-HIGH.

The program returns to DNC-MID automa-

tically after calibration.

Select DNC-LOW, for example, for loud en-

gine and heavy-bass music; select DNC-

HIGH, for example, for a quiet car and clas-

sical music.

• Press DSA until “DNC-MID”, “DNC-

HIGH”, “DNC-LOW” or “DNC-OFF” ap-

pears.

• Select “DNC-LOW”, “DNC-MID” or

“DNC-HIGH” with << >>.

With “DNC-OFF”, you deactivate DNC. Ap-

prox. 8 seconds after the last tuning, the set

reverts automatically to radio or CD display.

If you press DSA once more, the set reverts

to the former mode immediately.
