1 Safety regulations
Important
• Assembly, installation and servicing must be carried out by an authorised
electrician.
• Switch off the operating voltage before starting assembly or service work or
pull out the mains plug.
• Install the system …
- in a dust-free, dry environment,
-
so that it is protected from moisture, vapours, splashing water and dampness,
- somewhere protected from direct sunlight,
- away from the immediate vicinity of heat sources,
- at an ambient temperature of < 50 °C.
• Make sure the device is adequately ventilated.
Do not cover the ventilation slots!
• Avoid short circuits!
• No liability is accepted for damage caused by a faulty connection or inexpert
handling.
• Observe the relevant standards, regulations and guidelines on the installation
and operation of antenna systems.
• Earth the SAT receiver using the equipotential bonding rail in accordance with
DIN EN 50083 and VDE 0855.
• Do not perform installation and service work during thunderstorms.
Take measures to prevent static discharge when working on the device!
Electronic devices should never be disposed of in the household rubbish.
In accordance with directive 2002/96/EC of the European Parliament
and the European Council from January 27, 2003 which addresses old
electronic and electrical devices, such devices must be disposed of at a
designated collection facility. At the end of its service life, please take
your device to one of these public collection facilities for proper disposal.

2.3 Description
These twin-SAT cassettes enables the conversion of two TV satellite signals
of the same polarisation (horizontal or vertical) from the 1st SAT IF level
(950-2150 MHz) to the TV ranges band I to band V.
Each Cassette contains 2 channel strips with identical circuits. These are indicat-
ed in the display by Bx A or Bx B. The SAT signal transmitted via the SAT input
passes the SAT tuner, the video and stereo audio signal processing units and is
sent on to the combiner via a CCIR modulator. The combiner links the channel
strip A signal to the signal at channel strip B and transmits the signal via the HF
output socket of the HF bus bar. The signal can be set using the corresponding
level regulator (max. –20 dB). All other settings are made using the keypad of
the control unit of the head end.
After switching on the head end, the software version of the control unit is
displayed briefly in the two-line LC display. Approx. five minutes after the last
button has been pressed, the display switches off automatically or the software
version of the control unit is displayed.

2.4 Display of the software version
• Keep any two keys on the control unit of the head end pressed simultane-
ously until the display goes dark and the software version, e.g. “V.30”, is
displayed.
Important:
The head end requires a control unit with the V.27 software version or higher to
control these cassettes. For lower software versions, the software of the control
unit must be updated.
2.5 Scope of application
The cassettes are designed for use in the following head ends:
– CSE 3312
– CSE 3319

3 Assembly
3.1 Installing the Cassette
Warning
• Pull the mains plug out of the head end of the mains socket before insert-
ing or replacing cassettes.
• Unscrew the screws 1from the bracket in the head end.
• Insert the Cassette into a free slot and push it into the housing.
• Align the Cassette and gently make it contact with the connections of the
circuit board and the HF bus bar.
• Fasten the Cassette with the 1screws.

select parameters in the menus
– set values, initiate actions
– selects sub-menus
– Msaves all entries
– The parameters to be set are underlined (cursor).
5 Programming
The following examples show how to program the Cassette CCS 1233.
5.1 Preparation
• Connect the test receiver to the HF output of the head end.
• Set the output channel of the Cassette (see page 13) and adjust the test re-
ceiver to this channel.
• Switch on the modulator if necessary.
• Balance the output levels of the channel strips “A” and “B” if the difference in
level is ≥1 dB (see page 12).
• Measure the output level of the analogue cassettes and, if necessary, tune
them to a uniform output level.
