Connection and Setup

The following section is intended specifically for specialist dealers. You only need to read this section if you are carrying out the installation yourself.

The “Connection Examples” section provides a sample configuration. Do not connect the unit to the mains until all installation work has been properly carried out.

Refer to the information in the “Safety Instructions” section.

Connecting the Unit

Sat IF Connections

Connect the Sat IF inputs on the receiver to the satellite reception system.

Use coaxial cable with a standard F connector.

If the F connectors are not yet fitted on the cable, strip the insulation from the cables as shown in the following illustration and carefully twist the F connectors onto the ends of the cables until they are securely fitted.

When fitting the connector, make sure that no wires from the braiding are touching the inner conductor, so no short circuit can occur.

The quality of the reception signal depends on the connection.

Reception Requirements

Make sure that your own satellite antenna system is equipped at least with a universal LNB for digital reception in the high-band range.

Reception System Presets

The presets for the control signals have been made for standard reception systems, i.e. 14/18 V for polarity reversal and 22 kHz switching signal for low/high band changeover on multi-feed reception systems.

If tone-burst switch matrices are used in the reception system, the default selection in the installation menu, Antenna Setup, Tuner 1 and Tuner 2, under “DiSEqC™ Switch”, must be changed. Refer to the “Installation Menu” section on this, under “Antenna Setup”, “Tuner 1” and “Tuner 2”. Be sure to follow the operating instructions for the matrix used.
