with a shut-o switch. Only this way

can it be ensured that the device is

completely powered down in the in­terests of economical use of power.
Before starting up the device, please
remove the notice from beneath the

audio/video antenna.

Connecting the transmitter

Note:

Select a transmission source.

• SAT receiver/set top box

• DVD/CD player

• VCR

• PC, etc.
You can transmit video and audio
signals from the selected transmission

source.

Connecting the transmission source to
the transmitter:

Connect the SCART double adapter (

• 1()
with a CINCH (RCA) cable (2!).

Connect the CINCH (RCA) cable (

• 2!)
with the transmitter (e).

- 6 -

Note:

Observe the colour coding:

• "White" CINCH plug to white

CINCH socket

• "Red" CINCH plug to red CINCH

socket

• "Yellow“ CINCH plug to yellow

CINCH socket.
Connect the SCART double adapter
(1() to the AV socket of your transmis-
sion source (e.g. SAT receiver).

Adjusting the transmitter signals

The video transmitter (e) is designed
so that a suciently high output voltage
for faultless operation is supplied when
simultaneously connected to a source
(computer, DVD player, satellite receiver)
together with other devices via the in­cluded adapter. The local TV switch (i) in

the connection panel is then in the "YES"
position.

If only the video transmitter (e) is con-
nected to the video source, without

another device such as a DVD player/

VCR), image disruptions may occur for
some device combinations. In this case,
set the slider switch (i) to "NO" (= no
additional device connected). This lowers
the signal power so that the video and
sound are transmitted without distortions.

Note:

If the AV socket of your transmission

source is already in use, use the out­put of the SCART double adapter (1()
for the original connection . Connect
the infrared cable (2#) to the infrared
connection socket (u) of the trans-

mitter. Tape one of the self-adhesive
transmission diodes of the infrared

cable (2#) to the infrared receiver of

your transmission source.

Note:

Avoid attaching the transmission
diode directly to the infrared receiver

of your transmission source. Direct
remote control commands can now

be issued as usual.

Note:

Use the remaining transmission diodes

for additional devices. You can then

connect these devices with the trans­mission source. Connect the transmitter

(e) with a connector power pack (2@)
using the 6 V DC connection socket (t).

Connect the connector power pack (2@)
with a 230 V~/ 50 Hz wall socket.

Use the "ON/OFF" switch (r), which
is located on the side, to switch on the
transmitter (e). Rotate the antenna for
the remote control signals (q) upward.
Orient the audio/video transmitter an-

tenna (a).

Important!

The unlabelled side must point in the
direction of the receiver (f).

Switch on your transmission source. If

necessary, start playback on your trans-

mission source (e.g. SAT receiver/set top

box, DVD/CD player, VCR, PC etc.).

Connecting the receiver

Connect the other CINCH (RCA) cable
(2!) to the receiver (f) and the SCART­CINCH adapter (2)).

Note:

Be sure to match the colours correctly.

- 7 -

Plug the SCART-CINCH adapter (2)) into
the SCART socket of your TV. Connect

the receiver to the other connector power

pack using the 6 V DC connection socket
(j).

Connect the connector power pack
(2@) with a 230V~/50 Hz wall socket.
Use the "ON/OFF" switch (g), which
is located on the side, to switch on the

receiver (f).

Important!

The transmission channel
switch (o) and the reception
channel switch (l) must be
set to the same channel.
Otherwise radio transmission
is not possible.

Rotate the antenna for transmission of the
remote control signals (s) upward.

Orient the audio/video reception an­tenna (h) for the best image and sound
quality. The unlabelled side of the antenna
should point in the direction of the trans­mitter (e).

Improving the transmission quality

You can try the following measures to im­prove the quality in event of transmission
disruptions:

Orient the audio/video transmitter

•

antenna or reception antenna (a, h)

dierently.
Change the location of the transmitter

•

(e) and/or the receiver (f).

Change the position of the transmission

•

diodes of the infrared cable (2#) on

the infrared receiver of the transmission
source. The remote control signal quality
is improved.
Try a dierent channel, either A, B, C

•

or D.

Depending on the image source (DVD

•

player, SAT receiver, VCR, etc.) and

the image contents (with large bright
areas), overpowered video signals
may occur in combination with certain
TVs. These appear as distorted images.

In this case, you can use the local TV

switch (i) to adjust the transmission
level and eliminate the distortions.

Important!

If necessary, try positioning the receiver
(f) in a dierent location to avoid

interference eects.

Switch on your TV.
You can use the following connection

options on your TV.

The AV socket (SCART/CINCH

•

connection)

Point the remote control of the transmission

source at the infrared receiver (d) of the
receiver (f). The commands are sent to

your transmission source.

Transmitter connection examples

Note:

In general:
You can transmit signals from any

device that outputs a sound and/or
video signal on an appropriate

connection:

• CD player

• DVD player

• VCR

• Television

• SAT receiver/set top box

• Video camera

• PC graphics card

- 8 -

Special connection examples

PC as transmission source

You can transmit video signals from your
PC if the PC has a graphics card with

VIDEO output.

For sound, use the 3.5 mm mini-stereo
to CINCH female AUDIO adapter (2$).
Connect the transmitter (e) to the video

output of the graphics card.

Note:

Make certain that your PC is correctly

congured for outputting video on the

graphics card.

Connect your VCR to a "cable connec-

tion". Program your video recorder for

your "cable connection".

Please consult the operating manual of
your VCR for more information.
Then connect the transmitter (e) of the
radio transmission set to the AV socket
of your VCR. Switch on the VCR.
The VCR will transmit the congured "cable
channels" to the transmitter (e) via the

AV socket.

Switch the "cable channels" on the re-

ceiver (f) using the remote control of
the VCR.

Channel conguration

Television as transmission source

If video signals can be output via an AV
socket on your TV, then the TV can be

used as a transmission source.
Please consult the operating manual of
your TV for more information.

Connect the transmitter (e) to an AV
socket that may be used as an output.

Note:

Please note that most TVs must be
switched on for a signal to be output
on the AV socket. Image and sound
information coming from the TV can
then be transmitted.

VCR as transmission source

(Transmission of an audio/video signal,

e.g. cable connection).

Note:

You can use the VCR as a tuner for

transmitting audio/video signals.
You can also switch the cable chan-

nels using the VCR.

(parallel operation)

Note:

The data/signals sent from the trans­mitter are not encrypted. This means
that compatible devices within the

reception range are capable of
eavesdropping on the signal. The

radio transmission set uses an "open

standard".

Select between 4 dierent channels.

Note:

This makes it possible to operate up
to 4 transmitters (e) in the same area.
Make certain that the transmitter (e)

and receiver (f) are set to the same
channel.

Expansion options

Expand the radio transmission set by
connecting multiple transmitters (e) or

receivers (f).
