ABOUT THIS APPLIANCE

Your radio transmission system transmits signals wirelessly from an audio/video source to another audio/video device.

Typically, the radio signals are sent from a source with an aerial (e.g. a SAT receiver) to another device without an aerial (e.g. a different TV in the building) so that the first device's aerial can be used for the second device.

You can use the source remote control to control this device via the receiver. Your system will work over distances of up to 100m outdoors and 30m indoors.

It is also possible to connect the radio transmission system to a PC, for instance to transmit digital presentations onto a TV.

Possible signal transmitters and receivers

Typically, the system may be used to transfer the television reception from a satellite receiver, as the source, to another television in your house. Other audio/video sources can be a DVD recorder, a video recorder or a television, the "D-Box" (Premiere) or even a PC card. The device connected to the receiver may be, for example, a television or an amplifier.

Assigning the radio transmitter and receiver

The transmitter in the radio transmission system is connected to the audio/video source and the receiver is connected to a television or video recorder. The three-core AV cinch cable or the SCART adapter is used to connect the three types of signal – video, audio right and audio left – to the system.

GB

Controlling the audio/video source remotely

You can use the audio/video source remote control to control these devices from the point where the receiver is located. The (infrared) remote control signals are converted and transmitted as radio signals. The transmitter converts the radio signals back into an infrared signal. The two infrared transmitters in the infrared extender then send these signals on to the relevant devices.

Scart or Cinch

If the audio/video source has a SCART connection, use the SCART adapter for the transmitter. If the device connected to the receiver has a SCART connection use the SCART adapter for the receiver.

If the device connected to the receiver does not have a SCART connection use one of the three-core cinch cables. If the audio/video source has a 3.5mm audio output use the audio adapter supplied.

7

Range

Audio and video signals are transmitted in the 2.4GHz range. The range is approx. 100m in the open air and approx. 30m inside. The range may be less depending on environmental conditions.

Packaging

The radio transmission system is packaged to protect it against transportation damage.

Packaging is raw material and can be re-used or added to the recycling system.

CONNECTING THE TRANSMITTER

The transmitter is connected to an audio/video source (Source 1). This can be a SAT receiver, a video recorder, a DVD player, a television or even a graphics card (see below).

Via SCART connection

If the audio / video source has a SCART connection, connect the Mini DIN SCART cable for the A/V input (supplied) to this device's SCART output, and the Mini DIN input (AV IN 1) to the transmitter.

No SCART connection

If the audio/video source has no SCART connection, connect the Mini DIN AV cinch cable (supplied) to this device's A/V cinch output, and the Mini DIN input (AV IN 1) to the transmitter.

• The yellow cinch plug is for a video connection, the red one is for audio right, and the white one is for audio left.
• If you want to transmit sound signals only, connect the audio plugs only.
• If you want to connect the transmitter to a 3.5mm audio jack on an audio/video source, use the audio adapter and connect it to the audio plugs on the Mini DIN SCART cinch cable.
• Then connect the Mini DIN plug on the other end of the Mini DIN AV cinch cable to the appropriate socket on the transmitter.

• To send the video signal on to a TV set positioned where the transmitter has been set up, connect the Mini DIN SCART cable for the A/V output (AV OUT) to the SCART input on the TV.

Example of transmitter setup

The following diagram shows a typical arrangement with a satellite receiver and a TV on the transmitter side:

GB

Infrared extender (for remote control)

You have to connect the infrared extender if you want to be able to use the remote control from where the receiver is positioned.

• Connect the plug on the infrared extender to the IR-EXT socket on the transmitter (see diagram on previous page).
• Remove the paper backing from the sticky surface of one of the two IR transmitters and stick the IR transmitter onto the audio/video source so that it is aligned with the infrared receiver on this device. The top of the diode should be approx. 1 cm away from the infrared receiver (see diagram below).

Using more than one device

As the infrared extender has two IR transmitters, you can simultaneously operate more than one device remotely from the receiver. For example, you can use the video recorder as well as the DVD player in another room.

• Attach an IR transmitter as described above to each device that you want to use in another location.

Connecting more than one device

You can also connect a second device to the transmitter that

can send signals from this device to the receiver and control this device remotely from there.

• If you have connected the device to the transmitter's AVIN 1 input, the device is defined as Source 1, whereas it will be Source 2 if connected to the transmitter's AVIN 2 input.
• You can now use the SOURCE 1/2 switch on the transmitter to choose which signal is transmitted to the TV connected to the AV OUT output.

GB

Example of transmitter setup with two devices

The following diagram shows a typical arrangement with a satellite receiver, a TV and a DVD player on the transmitter side:

Connecting the mains adapter

• Connect the mains adapter for the transmitter to the 12V socket (DC 12V) on the transmitter.
• Remove the protective cover and insert the mains adapter into the socket (230V ~ 50Hz).
• Set the ON/OFF switch to the ON position. The red operating LED will light up.
• Open up the transmitter aerial and align it with the receiver.

GB

Selecting a channel

• Use the channel switch at the bottom of the device to select a channel (A/B/C/D) to which the signal is to be sent.

Setting up

• Place the transmitter on a sturdy surface.
• Align the flat side of the transmitter aerial with the receiver.

CONNECTING THE TRANSMITTER TO A COMPUTER

You can also connect the transmitter to a computer in order to transmit computer output to a television, for example.

It does not usually make sense to transmit computer output to a TV for running computer applications, since the TV's screen display is not usually good enough to display the higher resolution computer image.

If you want to show videos or presentations, however, displaying them via the TV is highly recommended.

The following requirements have to be fulfilled:

• Your computer has a video output that provides video images suitable for a TV.
• The operating system and the drivers for your graphics card support video output.

How to proceed

Output via video output is activated differently depending on your operating system and graphics card. As there are numerous combinations of these, we can only provide general instructions here. Please check the operating instructions for your computer or graphics card to see how you can divert the image to video output.

The following example requires a PC running the Windows® 98 operating system or above.

• Close all programs and switch off your computer.
• Refer to the operating instructions for your PC and follow the instructions for using video output.
• Connect the yellow plug on the AV cinch cable to the graphics card's video output. If your graphics card does not have a cinch output, use a suitable adapter (optional accessory).
• Connect the red and white plugs on the Mini DIN AV cinch cable to the appropriate audio output on your PC. PCs usually have 3.5mm stereo jacks, so you can use the adapter supplied.
• Connect the cable's Mini DIN plug to the transmitter's AV IN 1 input.
• Now switch on the transmitting station, the receiving station and your TV, and choose the appropriate video channel on your TV.
• Start your PC and wait until the operating system has fully loaded.
• Right-click once on the Desktop and choose "Properties" to show the "Display Properties":

• Now click on "Settings" to configure your PC's output.

Various graphics cards can differ enormously here.

You should therefore check the relevant operating instructions to see how you should proceed. You can usually use the F1 key to call up online help, which provides you with detailed information.

If all the settings are correct, the image from the PC will now be displayed on the TV.

CONNECTING THE RECEIVER

There are several ways to receive the transmitter's audio/video signals on a different device.

Connecting via a DIN AV cinch cable

• Connect the Mini DIN AV cinch cable to the receiver's AV EXTEND output and the corresponding sockets on the receiving device (e.g. the TV).

Connecting via the SCART adapter

• Connect the Mini DIN AV cinch cable to the receiver's AV EXTEND output and the SCART adapter for the receiver.
• Plug the SCART adapter labelled "Receiver" into the SCART input on the receiving device (e.g. the TV).

Example of receiver setup

The diagram below shows a typical setup for the receiver and a TV, either with the Mini DIN AV cinch cable or a SCART adapter.

GB

Interposing a device

Instead of connecting the receiver directly to the television, you can also interpose a different audio/video device. This could be a video recorder, for example, which you can then connect with the receiver as already described.

Connecting the mains adapter

• Connect the mains adapter for the receiver to the 9 volt connector on the receiver.
• Plug the mains adapter into an easily accessible socket (230V ~ 50Hz).
• Turn on the receiving device, such as the television, and set the receiver's ON/OFF switch to the ON position. The

red operating LED will light up.

Selecting a channel

Check that the receiver is set to the same channel (A/B/C/D) as the transmitter.

Selecting the source

If you have connected two devices to the transmitter, you can now use the SOURCE 1/2 switch to switch between the receiver of the first (Source 1) and the second (Source 2) device.

• To do this, keep the SOURCE 1/2 button at the top of the receiver pressed down for around 10 seconds, until the device switches over.
• You can also press down any button on the remote control belonging to a device that is connected to the transmitter for 10 seconds, and it will switch devices.

Setting up

• Place the receiver on a sturdy surface.
• Position the receiver so that the front with the LED operating indicator is facing you.
• If you are using the remote control from the audio/video source, point it towards the receiver.
• Open up the transmitter aerial and align it with the transmitter until you have the optimal image.

SETTING CHANNELS

Your radio transmission system has four channels – i.e., four different frequencies can be used.

The channel switch is on the bottom of both devices.

• Set the transmitter and receiver to the same channels.
• Test which channel (A, B, C or D) provides the best reception.
• You can also use the four channels to operate up to four radio transmission systems.

CLEANING/DISPOSAL

Cleaning

• Use a soft, dry cloth to clean the devices.
• Never use cleaning solutions that could damage the surface of the devices. Never spray cleaning fluids directly onto the devices.

Disposal

At the end of its life, the radio transmission system should not be disposed of in household rubbish. Seek the advice of your local authority on correct, environmentally-friendly disposal.

TROUBLESHOOTING

If errors occur, check first that the system was set up correctly. The following overview may help you:

No audio/video transmission

• Are all mains adapters plugged in?
• Are the transmitter and the receiver switched on?
• Are the channels for the transmitter and the receiver the same?
• Is the transmission source switched on?
• Walls and ceilings can reduce the signal range.
• Check the connections to the connected devices.

GB

Poor reception quality

• Realign the transmitter and receiver aerials.
• Change the position of the transmitter and the receiver slightly.
• Interference can be caused by several factors, such as radio waves from other devices.
• Choose a different channel.

The remote control does not react

• Point the remote control directly towards the receiver.
• The infrared transmitter's diodes should be approx. 1 ~cm away from the infrared receiver of the audio/video source.
• Have you aligned your infrared diodes correctly?
