1. Safety instructions
2. General description
IMPORTANT
Correct and proper use
If the system is handled incorrectly there is a risk of injury
from electric shock. The following instructions must be
followed, in order to avoid any risk of injury or damage,
and the operating instructions must also be adhered to.
The TV AVS 815 Power Transmitter is designed for use in dry, indoor
rooms. The power supply is provided by the mains adapter enclosed with
the Transmitter. Please only ever use this mains adapter.
It is not allowed to alter or modify any part of the system.
The unit is registered as a device that does not cause or suffer radio-
frequency interference, it is CE-approved, and it conforms with the Low
Voltage Directory.
The safety and installation instructions must be observed.
There shall be no guarantee cover against damage resulting from any
failure to observe these operating instructions, and no legal liability for
any resultant consequential damage.
-
-
It is never allowed to open the plug-in mains adapter
Only a properly qualified technician is allowed to check and
inspect the system.
The system is only ever to be operated in dry, indoor rooms.
Avoid high atmospheric humidity and extreme ambient
temperatures
-
-
-
-
Should any fault occur in the power supply the system should
be taken out of operation at once. Never replace defective
parts with anything other than original spare parts.
If there is any danger of a thunderstorm, it is a good
precaution to separate the system from the mains network in
order to protect it from lightning. The same applies if the
system is to be out of action for any length of time.
Power must be supplied at the correct rating at all times. This
applies in particular to the operating voltage in the system
and the mains adapter.
General functions
With the TV AVS 815 Power Transmitter you can transmit cable television
signals, and signals from other video equipment such as VCR, SAT-
receivers, and video cameras by radio.
The audio and video signals are transmitted in the 2.4 GHz range by the
AVS 815 Power Transmitter to the AVS 840 Power Receiver. The
maximum line-of-sight range is 300 metres.
The cable tuner integrated into the AVS 850 Power Transmitter is
controlled by the Power Receiver with the enclosed RC 815 infra-red
remote control. If you point the remote-control unit in the direction of the
infra-red window on the AVS 840 receiver, the infra-red signals from this
remote-control unit will be converted into radio signals which will in turn
be transmitted in the 433 MHz range to the AVS 850 Power Transmitter.
Inside the AVS 850, the radio signals are converted back into infra-red
signals and passed on to the integral cable tuner.
-
-
If there is ever any malfunction, the dealer from whom the
system was acquired must be asked to send it back to the
manufacturer for inspection.

3. Transmissions
If you use the infra-red remote control of another piece of video
equipment, these infra-red signals will be passed on via the RX 579 infra-
red module to the relevant appliance, such as a satellite-receiver, the
audio and video signals of which are being transmitted. In order to allow
this equipment, e.g. the satellite receiver, to be controlled via the remote
control to select programmes, the infra-red transmitter on the infra-red
module must be glued onto the infra-red receiver of the equipment that
is being remote-controlled.
Cabel-TV
SAT-TV
1st television set
When it is being glued on, attention must be paid to ensuring that the
"infra-red eye” of the unit is not completely covered over, so as to ensure
that direct control with the original remote-control unit is still possible.
AVS 850 Transmitter
The extension module possesses two infra-red diodes for controlling two
different units, e.g. a satellite received and a video-recorder.
Establish the position of the infra-red receiver with the aid of the
operating instructions for the unit that is to be controlled; if it is not
possible to locate it exactly, a little trial-and-error will be necessary. You
will thus have the possibility of controlling the unit, the signals of which
are to be transmitted, with the standard remote-c.

Fine-tuning the TV AVS 815 Power Transmitter
Parallel operation of a number of AVS 815 Power Transmitters
The AVS 850 power transmitter is able to transmit AV signals
over a distance of up to 300 metres (line of sight). Any wall or
concrete ceiling will represent a slight obstacle, and will thus
reduce the transmission range of the system.
The various different channel settings (1 to 4) enable up to four
Power Transmitters to operate in the immediate vicinity of one
another.

9. Rectifying a malfunction
Problem
Remedy
Poor transmission quality
1. Reflections of the signal can sometimes affect the transmission
quality. Move the Power Transmitter or Receiver away just a few
inches and this should solve the problem.
2. Change the channel settings (1 to 4) on the Power Transmitter
and the Power Receiver.
No transmission
1. Is the same transmission channel (1 to 4) set on the Power
Transmitter and on the Power Receiver?
2. Is the transmission distance too great? Reduce the distance
between the Power Transmitter and the Power Receiver. The
range is up to 300 metres line-of-sight, but walls and ceilings
reduce it.
3. Have you used the right scart cable?
1. If you operate wireless headphones or a similar wireless
transmitter on the same frequency as the AVS 815, this can
severely reduce its range.
Remote-control channel
2. Is the RX cable inserted into the AVS 850 and glued over the
infra-red eye of the unit that is being controlled?
RC 815 infra-red remote-control does not control the AVS 850
1. Wrong code set. Reset the code as described in Point 7.4.
