  • Page 20: General Information For Operation

    Operating Concept General information for operation The following explanations are important for understanding the logical menu structure of the MSK 33. Please take time carefully reading the following paragraphs. Menu selection The MSK 33 is operated via the buttons and various displayed screen menus. The selection of the menu items are effected by the softkey buttons on the right of the display.

  • Page 21: Operation

    To avoid heat build-up, the openings for the ventilators and the ventilation slots on the top of the unit must always be free. Use the leather case MZK 15 from Kathrein for mobile use. Mains voltage / mains switch The unit can be operated on AC current networks of 110...240 V with a network frequency of 50...400 Hz.

  • Page 22: Accumulator And Battery Operation

    Accumulator and Battery Operation Accumulator and Battery Operation Accumulator operation The accumulator of the MSK 33 is not charged in delivery status and must be charged before initial operation. To do so, connect the unit with the mains, and switch on the power supply with the mains switch on the front panel of the unit. When the green LED on the front panel lights up, the accumulator is charged.

  • Page 23: Connections

    Connections Connections RF output The receiving signal is fed into the RF input socket (BNC socket). It delivers also the remote power feeding voltage. The remote power feeding voltage is adjustable and disconnectable from 10 to 20V. For control, the red LED over the RF input socket lights up when the LNB voltage is switched on.
