Operating Instructions Device description

The Gira RDS flush-mounted radio consists of a

radio insert with operating top unit and loud-

speaker insert with cover plate. Either one or two

loudspeakers can be connected to the radio

insert. The radio automatically detects con-

nected loudspeakers and switches over between

stereo and mono mode. The radio is installed in

conventional flush-mounted device boxes. Oper-

ation of the radio is via capacitive operating but-

tons. 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.

Display

In normal operation, the display shows the sta-

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.

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

•TIME YES: The time is displayed. (This is the

standard setting.)

•TIME NO: The time is not displayed.

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 spe-

cifically 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 .

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.

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

(1or 2) for approx. 2 seconds.

✓If the station is saved the radio is muted and

the memory number is shown in the display.

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 automati-

cally 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

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.

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.

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.

Switching on automatically

The RDS flush-mounted radio can be switched

on with an external switch, for example in com-

bination with room lighting. This so-called aux-

iliary 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 car-

ried out in your home.

Volume when switching on

When switching on, the last station heard with

the last selected volume is called up.

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.

Reprogramming the memory

If the station preset is occupied by a station,

this is then reprogrammed with the new

station.

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 func-

tion can be carried out in your home.

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 maxi-

mum output level of the connected device is

insufficient to initiate AUX mode. In this case

the device cannot be operated with the flush-

mounted radio.

Note

The waiting time of 10 seconds is required so

that the flush-mounted radio does not inadvert-

ently leave AUX mode because of quiet pas-

sages between music titles.

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

During initial start-up, the RDS flush-mounted

radio automatically performs initialisation. This

includes determining how many loudspeakers

are connected and adapting the antenna to site

conditions.

Initialisation can also be triggered manually. This

is required in the following cases:

• The RDS flush-mounted radio was installed at

a new location.

• A second loudspeaker was connected.

• The time display should be switched on or off.

1. To trigger initialisation, press and hold the >>

and 2 buttons simultaneously for at least 5

seconds.

✓Either TIME YES (time is shown) or TIME NO

(time is not shown) appears on the display.

2. To change this setting, press either + (YES) or

- (NO).

✓After 5 seconds, INIT and a progress bar

appear on the display.

✓The radio generates two tones to determine

the number of loudspeakers.

✓The two strongest stations are automatically

stored as 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.

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.

Initial start-up

When the device is switched on for the first

time, automatic initialisation is performed:

• Either TIME YES (time is shown) or TIME

NO (time is not shown) appears on the dis-

play.

1. To change this setting, press either + (YES)

or - (NO).

• After 5 seconds, INIT and a progress bar ap-

pear on the display.

• The radio generates two tones to determine

the number of loudspeakers.

• The two strongest stations are automatically

stored as 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').
