SYSTEM REMOTE CONTROL

Changing the batteries

If the range of your infrared remote control seems to
decrease, or if certain individual functions can no longer
be carried out, you should replace the batteries.
Two micro 1.5 Volt LR03 size AAA are required. To
change the batteries, open the compartment on the
back of the remote control. Ensure that the batteries
are inserted properly (note the markings in the
compartment).

In the interest of the environment: 

Remember that batteries must always be
disposed of properly.

RADIO

TUNING TO RADIO STATIONS

RDS Radio Data System 

R

Your receiver is an RDS receiver. 
It is capable of receiving and evaluating RDS
information which is broadcast along with the
normal broadcast signal providing the listener
with more comfort and extra usefull information.
You can also call up other RDS services like RDS
time and radiotext provided that this information
is transmitted.(button 

INFO

, see page 25).

RDS Station name : 

If you are tuned to an RDS

station, the name of the station will be indicated
after a short time, overwriting names previously
stored.

RDS TIME : 

Some RDS stations broadcast the

'RDS-TIME' information. The time display is
updated every minute. The accuracy of the time
depends on the broadcasted information.

RADIOTEXT : 

More and more RDS stations

broadcast RADIOTEXT, which is additional
information on the station and programme being
broadcast. RADIOTEXT information appears as
"running" text in the display. RADIOTEXT is
transmitted character-by-character by the radio
station. As a result of that it may take some time
until the entire text has been completely received.

PROGRAMME TYPE : 

Each station can broadcast

a code (PTY) that characterizes the actual
program. With the 

PTY

button you can select the

type of programme you wish to listen to.

FM reception STEREO/MONO

Still, there are stations with disturbances or noise
in the audio signal, due to a weak signal.

sufficient reception quality is found.

TUNED

lights up when a station is tuned to precisely. 

– The frequency of the received station is

indicated in 

MHz

(FM).

– Stations which are received with a weak field

strength may be skipped. These can be tuned
to manually. 

• If desired, you can also interrupt the search by

pressing 

TUNING

.

Manual tuning

• Briefly press the

ADAPTING THE SURROUND MODE VALUES

Adapting the Surround mode values

The surround mode has programmed values for
centre-mode, centre and rear levels and for rear
channel time delay which are suitable for most
common applications.
You can , however, change these settings to your
particular taste or speaker installation.

To install your Surround system proceed as
follows:

• Select the Dolby Pro Logic mode.
• Press the 

SURROUND

key longer than 2

seconds.

– The display shows e.g.‘

’.

• Use the 

# $

(

select the centre channel mode: 

NORMAL

,

WIDE

or 

PHANTOM

.

– Select 

NORMAL

if you are using a normal

centre speaker.

– Select 

WIDE

if you have connected a HiFi

centre speaker

– Select 

PHANTOM

if you have not connected a

centre speaker, but still wish to simulate the
sound coming from the centre.

• Press the 

SURROUND

button again.

– The display shows e.g. 

DELAY 20

• Use the 

# $

(

TUNING

or

adjust the delay time of the rear channel 
(15, 20 or 30 ms). 
Increasing the rear delay time expands the
perceived listening area, and vice versa.

• Press the 

SURROUND

button again.

– You will now hear a test tone from the left,

centre, right and rear speakers in turn, in a
repeating cycle.

– The display shows e.g.

TEST FR

TEST R

TEST FL

• The values of the centre and rear level can be

adjusted if you press 

# $

(

TUNING

or

the test tone of the centre 

TEST C

and the

rear speaker

.

• When you are satisfied with the levels, press

the 

SURROUND

button again to turn off the test

tone and leave the installation mode.

Note:

When you have selected 

PHANTOM

for the

centre channel mode, the test tone sequence will be
as follows: 

TEST FL

TEST FR

TEST R

TEST FL

Direct adjustment of rear and centre level

During e.g. a film, it is possible that the special
effects on the rear speakers become too loud or
too quiet compared to the level of the dialogue,
making it necessary to perform small adjustments.
Your

remote control

is, for this purpose,

provided with two keys for direct adjustment:

Adjusting the rear level

• Press the 

– REAR

button.

The display shows e.g.

(related to the front level).

Adjusting the centre level

• Press the 

button.

The display shows e.g.
