Selecting a 12 or 24-hour mode

You can choose whether the time is dis-

played in a 12 or 24-hour mode.

If necessary, refer to the section on “DSC

programming - CLK, MODE”.

Synchronisation

To improve the accuracy of the internal

clock, it can be synchronised on a regular

basis. This is only possible when the time is

received via an RDS-CT signal and the au-

tomatic synchronisation feature is switched

on (default setting).

If the RDS-CT signal is not available, the

audio system will attempt to receive the

DCF-77 time signal (atomic clock) to cor-

rect the time the next time it is switched off.

The display will indicate “CLK Sync” while it

is synchronising the time.

If you would like to switch off the synchroni-

sation feature, refer to “DSC programming -

CLK, SYNC”.

Setting the equaliser

The acoustic characteristics of the car inte-

rior affect the quality of the sound repro-

duced in your vehicle to a much greater ex-

tent than the speakers.

Position, installation and the rear volumes

of, for example, the door or rear window

shelf all play an important role.

Even the sound produced by well selected

and installed speakers can be affected neg-

atively by resonance frequencies in the ve-

hicle interior.

As a result, the bass sounds may be lost or

reverberate, the mid-range tones sound too

overpowering and music instruments or

voices may be distorted or the total sound

quality may be completely lifeless.

The overall sound quality can be greatly

enhanced if certain frequencies are sup-

pressed or boosted.

This car stereo is equipped with 2 paramet-

ric filters. The first filter “LOW” can be set

from 32 to 500 Hz, the second filter “HIGH”

from 630 to 10,000 Hz. In this context, par-

ametric means that it is possible to set one

frequency for each of these filters and ei-

ther boost or reduce it (+10 to -20 dB) indi-

vidually.

These parametric filters can be adjusted to

very exact settings even without the help of

measuring instruments.

The individual steps you have to take to

make these settings are described in the

table.

Notes on making the settings

The following notes are intended as recom-

mendations only. They do not necessarily

reflect your own personal sound preferenc-

es.

We recommend that you use a music cas-

sette or CD you are familiar with to make

the settings.

The cassette/CD should include tracks with

different instruments and vocals. Purely

electronic music is not well suited to serve

as a basis for making the settings because

the original sounds cannot be determined.

Before you set the equaliser, set bass, tre-

ble, balance and fader to “0”.

This setting is described in the Quick Refer-

ence under 9 AUD.

Now listen to the cassette/CD you have se-

lected.

Evaluate the sound according to your own

personal preferences.

Now refer to “Sound impression/problem” in

the table and you will find suggestions to

eliminate any problems under “What to do”.

Make the settings for bass and the lower
