Blaupunkt RCM 169 Adjusting DNC sensitivity, Switching DNC on/off, Safety information

DNC – Dynamic Noise Covering

DNC is used when the vehicle is in motion to boost the car audio system’s volume to a level which is considered pleasant in the stationary vehicle.

The volume is boosted at different levels for the different frequency ranges, depending on the amount of noise which develops in the vehicle.

To start taking the reading:	To alter the sensitivity
• Press DSA.	• press DNC briefly, the value selected
	will appear in the top line of the dis-
	play.
	Press / to alter the value as desired.
	Press ENT to store this new setting and
	press EXIT to quit the DSA menu.

This keeps the volume and the sound of the audio equipment at acceptable levels while the background noise changes. Short-term noise, such as the noise made when you drive over a set of railway tracks, will not affect the volume.

Adjusting DNC

If DNC is to operate correctly for your vehi- cle, it is necessary to take a reading with the microphone. Take the DNC reading af- ter you take the hi-fi self-adjustment read- ings. Use the enclosed tape to secure the microphone somewhere near the dash- board, but not in the foot area, near any- thing that reverberates or near the heating/ cooling fans.

The microphone head must be facing to- wards the passengers. The reading should be taken in a quiet area with the engine switched off.

•Press DNC for approx. 1 sec. until “DNC Adj” appears in the top line of the display.

The DNC reading will now begin and be completed fully automatically.

As soon as “DNC 3” appears in the top line of the display, the reading has been com- pleted. The value will be set to average DNC sensitivity automatically.

Adjusting DNC sensitivity

The volume boost can be set to five differ- ent levels:

Select DNC 1 if you have a loud engine and usually listen to music with a lot of bass, select DNC 5 if your vehicle runs very qui- etly and you usually select classical music. After you have taken a reading, the value will automatically be set to DNC 3.

Switching DNC on/off

•To switch DNC off, press <<.

”DNC off” will appear in the top line of the display.

•To switch DNC on, press >>.

Safety information

If the microphone is placed in the wrong position, the DNC reading will be incorrect.

As a result, the volume might be boosted too much while you are driving (could star- tle the driver).

Please make sure to position the micro- phone correctly.
