Introduction
Congratulations on buying the Marmitek VideoControl3. With the infra-red extender VideoControl3 you can transmit infra-red signals via the existing COAX network in your home and control all equipment connected from another room. Example: you have a satellite receiver in the living room and a second TV in the bedroom, where you would like to watch the satellite programs. You would like to control the satellite receiver with
the remote control, but do not want to go to the living room. The infra-red extender VideoControl3 transmits the infra-red signals to the equipment via the COAX cable network.
Set content
• 1 VideoControl3 infra-red receiver with 1 IR LED (IR receiver)
• 1 VideoControl3 infra-red transmitter with 3 IR LEDs (IR emitter)
- 2 power adapters
• Coax extension plugs (IEC-F) male and female
- This user manual
How does it work?
The VideoControl3 transmits the signal from your own remote control back to the other room via the existing antenna cable. The VideoControl3 consists of an infra-red receiver and an infra-red transmitter. The receiver is connected to the antenna connection of a TV (e.g. in the bedroom).
The transmitter is connected to the antenna connection of e.g. the satellite receiver. You can control up to three different devices (e.g. a satellite receiver, a VCR and a decoder) using the three infra-red LEDs. If desired, you can place multiple infra-red receivers in different rooms, to control your video equipment from each TV in your house.
NOTE: The Marmitek VideoControl3 signal is carried via all antenna boxers, splitters and antenna amplifiers suitable for a return channel.

Installing the receiver

- Connect the 'IN' side of the VideoControl3 receiver, (with the character R on the device, with the IR LED) to the COAX cable near the TV in the room you want to use the remote control from (e.g. the bedroom).
- Plug the 'TO TV' plug of the receiver into the antenna IN of the TV.
-
Use the coax extension plug included if necessary.
-
Position the IR LED within range of the remote control, e.g. on the top of the TV.
- Plug the power adapter into the wall socket.
Tip 1
There are two types of antenna plugs in Europe: the IEC plug and the F plug. This last one causes the least loss of signal and is used in superior installations. Your Marmitek VideoControl3 also uses an F plug. With the adapters included you can also connect IEC plugs.
Installation of the transmitter

- Connect the 'IN' side of the VideoControl3 transmitter (with the character T on the device and with the IR LEDs) to the COAX cable near the satellite receiver or video recorder in the room the equipment you want to control is situated.
- Connect the 'TO TV' plug to the antenna IN of the TV or satellite receiver.
- Use the coax extension plug included if necessary.
- Stick the LEDs on the IR windows of the equipment. This should be done very carefully and precisely. Test whether the LEDs are in the right place first (with another person holding them) before you stick them down.
- Plug the power adapter into the wall socket.
ATTENTION: if you connect less than 3 devices, do not remove the other LEDs from the cable.

You have now successfully installed the VideoControl3. The red LED on the receiver and transmitter will light up as soon as you transmit a command with your remote control.
Tip 2
The receiver has a adjustment screw which you use to set the sensitivity of the reception. If the red LED lights up when it is not being activated via the remote control, the sensitivity is too high. If the LED does not light up when you are using the remote control, it is set too low. Use a Phillips screw driver to change the setting.
Tip 3
If you want to control your equipment from multiple rooms, you can purchase extra receivers (Art. No. 9709 (E), Art. No. 9715 (UK).
Frequently asked questions
I have no picture and no sound.
Check whether all the cables are connected properly.
The infra-red doesn't work.
a. Check whether the infra-red LED is placed on the sensor correctly.
b. Check whether all the cables are connected properly.
c. Check whether the LEDs on the transmitter and receiver flash up if the IR signal is activated. You can alter the sensitivity of the receiver by setting the adjustment screw, see tip 2.
d. The infra-red return channel only works if you are using amplifiers, splitters and antenna boxes that support return channels. This is usually indicated by the term '5-30MHz' or '5-68MHz'. Consult your cable store for more information.
e. Make sure the transmitter cannot control the receiver. The LEDs on the transmitters have to be out of view of the LED on the receiver (acoustic feedback).
f. Make sure that, if you use multiple receivers, these do not all receive an IR signal at the same time.
g. Prevent interference from other IR sources, such as sunlight, energy lamp and/or plasma screen.
