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.

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

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.

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-

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.
