POWER SUPPLY AND CONTROL OF LNB
Press the
LNB
key to supply an LNB. The power-supply voltage is selected turning the shaft
encoder; the indication on the status bar enables to check the selected voltage. To stop the
power supply press the
LNB
key again. When the LNB is powered, the
ON
indicator lights
up. When the absorption of the powered device is higher than 50 mA, also the
CONT
indicator lights up; in case it does not light up, the down cable may be cut off or the LNB
may be disconnected (or broken). If absorption exceeds 500 mA, protection intervenes
emitting a beep and interrupting the power supply.

LNB ENGAGED MENU
This menu is activated keeping the
LNB
key pressed. Once the desired operations have
been carried out, press
LNB
again to exit.
⇒
MODE: there are two available modes to change the power supply of the LNB:
•
Step - voltage changes for discrete values 0, 5, 13, 15,18 V and, if enabled, 24 V;
•
Continuous – voltage changes from 5 to 18 V (24 if enabled) in continuous mode
with 0.2 V steps.
⇒
STEP: to set the voltage step at LNB’s switching on
⇒
22 KHz: to activate/deactivate the 22 KHz tone
⇒
AMPERE: to activate/deactivate the display of power absorbed by LNB instead of
supply voltage
⇒
24 V: to enable/disable the 24 V step or the range between 18 and 24 V.
⇒
AUTORESET: to set the auto-reset of the LNB’s voltage.
⇒
PLEASE NOTE: if no load is connected, the LNB’s voltage could decrease very slowly due
to internal filter capacitors.
⇒
PLEASE NOTE: if you are inside satellite band and you change to outer tuning, you shall
switch off the LNB for safety reasons.
