If your instrument does not provide any more remote power supply to TV mast amplifier, check the following points.
a) Check if the switch “DC@RF IN”, available in most models, is set to ON: see examples figures 1 and 2.
b) Ensure that the YELLOW LED “DC@RF IN” on the front panel of the instrument lights on;
c) Activate in the measure MENU, the power supply voltage by selecting in the “DC@RF” the desired voltage value: 5/12/18 or 24 VDC (see example Figure 3);

of remote power supply DC@RF IN example
d) If the LED lights up, but after a few seconds that you connected the MAST-AMPLIFIER, the instrument does NOT provide any more voltage (the spectrum of the received signals decreases sharply or measures are interrupted), check:
In this case, the instrument must be sent to ROVER for repair (NOT covered by warranty).

IMPORTANT: For safety reasons, the power supply voltage (only in TV and CATV), SWITCH OFF automatically when changing function (eg HOME, SAT, PLAN) or when power is turned OFF.
