The Gira RDS flush-mounted radio consists of a
radio insert with operating top unit and loud­speaker insert with cover plate. Either one or two
loudspeakers can be connected to the radio
insert. The radio automatically detects con­nected loudspeakers and switches over between
stereo and mono mode. The radio is installed in
conventional flush-mounted device boxes. Oper­ation of the radio is via capacitive operating but­tons. The operating top unit is equipped with a
display showing the station text (RDS) etc.
External music sources, for example an MP3
player, can be fed into the radio via an AUX
input.

tion name, frequency and time. Display of time

is coupled to the RDS signal received and cannot

be set manually.

With weak station signals, the station name and

time may not be displayed. Instead of this the

station frequency is shown in the display.

Information on RDS text

In some cases, the texts shown on the display
may differ from the texts transmitted by the
station.
Unexpected texts may be displayed when
unsupported characters are received. This is
not a malfunction.

Operation

Operation only requires a light touching of the
symbols.

An overview of the most important functions:

a quick press switches the radio on/off;
a long press switches the radio into sleep mode.

>>

a quick press starts manual station search.
a long press starts automatic station search;

+ / –

pressing – lowers the radio volume;
pressing + makes it louder.

1 / 2:
a quick press calls up a saved station;
a long press saves stations.

Switching on the radio

Any button can be pressed to switch on the
flush-mounted radio. It is not necessary to spe­cifically press .
When switching on, the last station listened to is
switched on with last selected volume.
The radio remains switched on until it is
switched off by pressing .

Switching on automatically

The RDS flush-mounted radio can be switched
on with an external switch, for example in com­bination with room lighting. This so-called aux­iliary unit function is however dependent upon
the individual installation environment of your
house or flat. Ask your electrical installer
whether auxiliary unit functionality can be car­ried out in your home.

Setting volume

Volume is set via + and –.

Volume is raised with +,
and lowered with –.

During setting, the current value of volume is
shown by the display:
VOLUME 1 for the lowest level,
and VOLUME30 for the highest level.

Searching a station

To initiate the automatic station search function,
press and hold the >> search button. During the
search the radio is muted and >>> is shown
in the display. As soon as a station is located the
search function stops and the station becomes
audible.

To manually search for a station: Briefly press

>> several times until the desired frequency is

located. Each press of the button increases the
frequency by 0.1 MHz.

Station search

The search direction is ascending. If the upper
frequency limit (107.9 MHz) is reached, the
radio switches to the lower frequency limit
(87.5 MHz) and continues searching. If the
search returns to the initial frequency, the radio
switches automatically to a higher sensitivity
level. In this way, weaker stations may also be
received.

Saving a station

The RDS flush-mounted radio has two station
presets, each of which can save a station setting.

Saving:

1. Select the desired station with the station
search function.

2. Press the corresponding memory button
(1 or 2) for approx. 2 seconds.

✓ If the station is saved the radio is muted and

the memory number is shown in the display.

Reprogramming the memory

If the station preset is occupied by a station,
this is then reprogrammed with the new
station.

Calling up a station

Briefly press a memory button (1 or 2) for calling
up a pre-set station. The pre-set station is
located and the corresponding memory number
is shown by the display.

Sleep mode

In sleep mode the radio switches off automati­cally after 30 minutes.

To activate sleep mode, press for
approx. 2 seconds when the radio is switched
on until Sleep is shown by the display.

To deactivate sleep mode, briefly press . The

Sleep display is suppressed.

Using an external audio source

Installation note

For connecting an external audio source, a
cinch socket outlet must be installed in addition
to the flush-mounted radio.
Ask your electrical installer whether this func­tion can be carried out in your home.

The RDS flush-mounted radio is able to generate
the audio signals of an external source (e.g. an
MP3 player).

This function is demonstrated with an MP3
player in the following example:

1. Connect the MP3 player via a suitable adapter
cable (e.g. cinch - jack) to the cinch socket
outlet.

2. Switch on the MP3 player and start playback.

✓ The RDS flush-mounted radio switches auto-

matically to AUX mode:

• AUX appears in the display,

• the music from the MP3 player is generated

via the radio loudspeaker.

Note

If the flush-mounted radio does not switch
automatically to AUX mode, the volume of the
connected device must be increased.

In individual cases it may occur that the maxi­mum output level of the connected device is
insufficient to initiate AUX mode. In this case
the device cannot be operated with the flush­mounted radio.

3. The volume can be modified as accustomed
via + and –;
the buttons >>, 1 and 2 have no function in
AUX mode.

4. For switching off or for changing to radio
operation the MP3 player is simply switched
off.

✓ When the MP3 player is switched off, the radio

returns to its state of play prior to switching to
AUX mode after 10 seconds.

Note

The waiting time of 10 seconds is required so
that the flush-mounted radio does not inadvert­ently leave AUX mode because of quiet pas­sages between music titles.

Volume when switching on

When switching on, the last station heard with
the last selected volume is called up.

Further display information:

• 1 / 2: the radio displays a saved station

• Sleep: the radio is in sleep mode

• > > >: the radio carries out an automatic
station search

• AUX: the radio generates an audio signal fed
in via the AUX input

• INIT: the radio carries out initialisation

• VOLUME: displayed during volume
adjustment

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 combina­tion 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-

RDS

ence can be minimised by increasing the dis­tance between the devices.

2280 ..

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 con­nection cables of the loudspeaker insert in
the flush-mounted device box of the radio
insert.

Support ring seal

Loudspeaker connection

Either one or two loudspeakers can be con­nected to the RDS flush-mounted radio:

Terminal Connection cable

+red

–black

The maximum cable length between the loud­speaker 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 flush­mounted 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.

Use the same phase

The same phase L must be used for the auxiliary
input (1) and the power supply of the radio insert
(L).

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 con­nected to the AUX IN terminals of the RDS flush­mounted 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 out­let.
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.

Retrofitting a second loudspeaker

If a second loudspeaker is connected to the
flush-mounted radio at a later date, initialisation

Initial start-up

When switching on for the first time initialisa­tion begins automatically:

must be manually triggered (see 'Manual initial­isation').

• The display shows INIT and a progress bar.

• The radio generates two tones to determine

nection of the flush-mounted radio can alterna­tively be carried out via the switched phase. In
this case however the flush-mounted radio may
only be operated with lighting switched on.

Manual initialisation

With initial start-up the RDS flush-mounted radio
automatically carries out an initialisation that
determines the number of connected loudspeak­ers and adapts the antenna to site conditions
etc.

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.

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 flush­mounted 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 automatical­ly stored in the station presets 1 and 2.
