Setup

When selecting the installation site, consider the room conditions, meaning the location of the next outlet, etc. Also prevent direct sunlight, vibrations, dust, heat, cold and dampness. Keep the appliance away from strong transformers or motors.

Operate the device only on a stable, level surface. There must be enough space around the system for air circulation to permit dissipation of the generated heat. Therefore, only place the device on a level surface and not on carpets, etc. Do not cover up the ventilation slots in the casing.

If you do not heed these instructions, the device may be damaged.

Do not drill extra holes or screw any extra screws for mounting purposes into the case. This will damage the device.

Make sure you position the appliance in a safe and stable place, away from objects that might fall on it, thereby avoiding unwanted accidents.

Because of the variety of used lacquers and polishes for furniture, the device base might leave residues on furniture due to a chemical reaction. That's why do not place the device without appropriate protection on the valuable furniture surfaces.

Connection

Make sure before connection that the cables are disconnected from the mains. Disconnect all other devices from the mains which are also to be connected.

Make sure that the cables are connected to the right side, that is, left to left and right to right.

Connection of cinch outputs, remote control and antenna

For the connection of the cinch sockets only use the cinch wires provided or other suitably isolated cinch wires. The use of other cables may lead to interference. To avoid distortion or mismatching which could damage the device, only devices with cinch outputs may be connected to cinch inputs.

Use the enclosed remote wires for connection of remote control elements

The white cinch socket is to be connected with the left cinch connection of the amplifier.

The red cinch socket is to be connected with the right cinch connection of the amplifier.

• Connect the connection OUTPUT to the TUNER input on your amplifier.

• If you're using the HiFi amplifier A-1000, connect the remote control input REMOTE SYSTEM TO AMP with the corresponding control socket REMOTE SYSTEM TUNER on the amplifier. You can the control the tuner with the system remote control.

• Attach the enclosed projection aerial to the inner contact of the connection ANTENNA FM 75U. Position the aerial so as to attain the best reception.

For better reception, this connection can also be connected to your house aerial or cable connection. For this purpose, use an unsymmetrical 75 Ohm aerial cable.

• Attach the enclosed frame aerial to the ANTENNA AM LOOP connection Position the AM frame aerial so as to attain the best reception. The AM frame aerial may be placed on a level surface or mounted on a wall.

Position the aerial as far away as possible from all possible sources of interference (motors, power cables, radion installations etc.).

RDS-Features

The abbreviation RDS stands for Radio Data Syste, that is, inaudible coded additional information is transmitted through the UKW-RDS transmitter. With your tuner, you own a TU-1000 device which is able to process these coded data transmitted by many stations.

Programme Service (PS)

Information consisting of a max. of 8 alphanumeric characters. They identify which radio station is presently being received. This information is shown directly in the display of the device (e.g. BAYERN 3).

Programme type (PTY)

This code gives the receiver information about the type of the transmitted programme (e.g. sports, classic, news etc.). The listener can select his favourite programme purposefully.

Some stations used the radio text (RT) function to send messages. The message then runs from left to right across the display.

A national disaster alarm can also be prepared this way. However, not all the radio stations offer the PTY service.
