The tones control system is very efficient. Above the large tone control knobs there is a band that lights up gradually indicating the emphasis on the band on which it acts.

Inside the cabinet there is a dipole for FM reception and a ferrite rotating aerial for AM reception.
Ferrite aerial can be rotated from the outside to achieve a perfect tuning of the device in the AM.
In this picture see the rotation mechanism and the position indicator of the aerial.
The reception sensitivity with internal aerials is very good. This unit was in fact produced in a period when there were not many radio stations and those available fairly apart from each others.
Using an external aerial sensitivity is further increased.

The tuning system is another gem.
The unit is equipped with mechanisms for keeping separate the AM bands by the FM bands.
The tuning knob is single but a selector switch commutes into cable systems (all in steel) and pulleys separated depending on the band.

The knob outside the shutters has a double function:
- On/off button (push)
- Volume control (turn)

You can therefore easily avoid to open the shutters to control the device.
The outer knob glows red when the radio is turned on.

The shutters’ cladding canvas needs to be acoustically as transparent as possible. It is a robust but holed canvas in order for the light to go through.
If you closed the shutter when the radio is on the effect created by the visible rear lights would be rather unpleasant.
Siemens solved this:

- When you close the left shutter the magic eye turns off automatically
- When you close the right shutter the lightning of the dial scale switches off

The device is equipped with a double-position equalizer commutator :

Musik – the entire sounding spectrum is reproduced
Sprache – only the central part of the spectrum is reproduced.

The indicator lightens up on the scale when in Sprache position.

The magic eye has of course been replaced.

There are four louspeakers.
Two 21 cm (8.2 inches) very efficient bicone and known by experts using these louspeakers to create amplifiers.
The radio is equipped with two cone tweeters assembled on the acoustic lens.
That creates a pleasant ambience and a side diffusion as widespread as possible.

The controls are placed in an unusual way.
On the left there is the rotation control of the ferrite curve.
On the right you can see the magic eye indicating the perfect tuning of each station.
Below the magic eye you can see the equalizer indicator Sprache/Musik above mentioned.
Then the Short, Medium and Long Waves AM scale is to be found together with the differently colored FM scale.

Lastly you can see the tuning knob, whose two supporting big fly-wheels make its movement very pleasant.
Below you can find the bass control knob.
In order then: the Sprache/Musik, record player, Long, Short and Medium Waves, ferrite curve, OM narrow band and FM commutation buttons.
Lastly, on the right, the acute control knob.
The illuminated small knob outside the shutters allows the volume control (with incorporated loudness)
