Mounting Instructions Installation
The inserts of the flush-mounted radio can be
installed in flush-mounted device boxes one
below the other or next to each other as desired:
1. Install the loudspeaker insert and lay the con-
nection cables of the loudspeaker insert in
the flush-mounted device box of the radio
insert.
2. Connect the power supply (230 V) to the L/N
terminals of the radio insert.
3. Connect the auxiliary input (1) if required (see
"Auxiliary unit function").
4. Connect the loudspeaker connection cables
to the radio insert (see "Loudspeaker connec-
tion").
5. Install the radio insert into the flush-mounted
device box.
6. Remove the protective cover from the loud-
speaker insert.
7. Apply the cover frame and attach the loud-
speaker cover and operating top unit.
Loudspeaker connection
Either one or two loudspeakers can be con-
nected to the RDS flush-mounted radio:
The maximum cable length between the loud-
speaker and radio insert is 20 m.
Mono operation
If only one loudspeaker is connected, sound is
generated in mono quality.
With connection of only one loudspeaker the left
channel (L+ / L–) must be used. Loudspeaker
impedance must not exceed 4 ohms.
Stereo operation
If two loudspeakers are connected to the flush-
mounted radio, the radio signal is generated in
stereo quality.
Auxiliary unit function
The RDS flush-mounted radio is equipped with
an auxiliary input. This for example enables
switching of the radio via a switch or automatic
control switch together with room lighting. For
this purpose, the switched phase is laid from the
switch to the auxiliary input (1) of the radio.
If no permanent phase exists in the room, con-
nection of the flush-mounted radio can alterna-
tively be carried out via the switched phase. In
this case however the flush-mounted radio may
only be operated with lighting switched on.
Connection of AUX input
The RDS flush-mounted radio is equipped with
an AUX input via which external music sources
such as MP3 players can be connected. For this
purpose an additional cinch socket outlet is con-
nected to the AUX IN terminals of the RDS flush-
mounted radio. The maximum cable length
between the cinch socket outlet and radio insert
is 3 m.
The external music source is then connected to
the RDS flush-mounted radio with an adapter
cable (e.g. cinch - jack) via the cinch socket out-
let.
Upon switching on the external music source,
the RDS flush-mounted radio automatically
switches to AUX mode and generates the signal
of the external source.
Manual initialisation
With initial start-up the RDS flush-mounted radio
automatically carries out an initialisation that
determines the number of connected loudspeak-
ers and adapts the antenna to site conditions
etc.
If a second loudspeaker is connected at a later
date or the flush-mounted radio is installed at a
new location, initialisation must be triggered
manually:
1. Press the buttons >> and 2 simultaneously
and hold for at least 5 seconds until the flush-
mounted radio is muted.
✓ Initialisation proceeds:
• The display shows INIT and a progress bar.
• The radio generates two tones to determine
the number of loudspeakers.
• The two strongest stations are automatical-
ly stored in the station presets 1 and 2.

Important
Installation and mounting of electrical devices
may only be carried out by a qualified
electrician.
The RDS flush-mounted radio must be installed
protected from dripping and sprayed water in
indoor areas.
Electronic devices cause interference signals
which may be picked up by radios. Reception
interference may therefore result in combina-
tion with electronic devices in one installation
unit or in close proximity (e.g. ballasts). For this
reason, carry out a functional check on-site
before installing such a combination. Interfer-
ence can be minimised by increasing the dis-
tance between the devices.
i
Support ring seal
The support ring of the loudspeaker insert is
coated with a film that provides acoustic isola-
tion of the insert from the front sound opening.
This support ring seal must not be removed
and, apart from holes caused by the attachment
screws must not be damaged, as otherwise
bass reproduction may be impaired.
i
Initial start-up
When switching on for the first time initialisa-
tion begins automatically:
• The display shows INIT and a progress bar.
• The radio generates two tones to determine
the number of loudspeakers.
• The two strongest stations are automatically
stored in the station presets 1 and 2.

Retrofitting a second loudspeaker
If a second loudspeaker is connected to the
flush-mounted radio at a later date, initialisation
must be manually triggered (see 'Manual initial-
isation').

Information on improving reception
With poor reception conditions, reception
can be improved by extending the left-hand
loudspeaker cable (L+/L–) to 75 cm if
installation conditions permit.
