LNB Voltage and 22 kHz/60 Hz Change-Over
The LNB supply voltage can be obtained from the RF socket. For
checking purposes, the LED beside the RF socket flashes when the
voltage supply is switched on. The power consumption of the connected
LNB is displayed on the LCD.
The additionally connectable 22 kHz square-wave signal or the 60 Hz
square-wave signal respectively will superimpose the LNB voltage when
connected. It is necessary, e. g., for the change-over of multifeed
systems or high band/low band LNB’s.
The LNB voltage is disengageable.
• Disengageable = 0 V
• Adjustable from 5 V to 20 V in 0.1 V steps
• Short-circuit proof (max. current 500 mA from 10 V to 20 V)
(max. current 100 mA from 5 to 9.9 V)
The following voltages can be called up via short cut:

Calling up LNB voltage 14 V:
Press [2ndF] [LNB] [2]
LC display:
• LNB voltage: 14 V
• Power consumption: 150 mA
Note
Press [+] or [-] to adjust the LNB voltage in 0.1 V steps.
By calling up a different function, e.g. [2ndF] [CH-FRQ], the LNB menu
will be closed automatically.
