7.- Avoid locations with possibilities of spilling liquids on the inside of the device, and with important changes of
temperature.
8.- Use the equipment only in moderate climates (not in tropical climates).
9.- Never open the cover of the power supply due to electric risk. In case of problems, go always to qualified
technicians.
10.- Never, under no circumstances, open the equipment connected to the electrical net.
11.- During the handling it is better to disconnect the equipment of the electrical net.
12.- Respect the electricity security rules during the assembling. Use materials that obey the current law.
13.- The connecting plug must be accessible in a fast and simple way to have a fast disconnection.
14.- Never touch the plug with wet hands. Also, disconnect always the device before handling the connections.

Amplifier HLA-ST

1.3. Description and connections

The HLA-ST amplifier can be used as:
RF headends: If we adjust its terrestrial and satellite inputs separately TER and SAT. The input (SAT+TER) will only
input the satellite IF signal and the TER input will only input the terrestrial signal.
Line amplifier: If we adjust its inputs as combined using the SAT+TER input to pass through both bands and the TER
input will be disconnected.
It allows feed devices connected by its inputs or its output. The amplifier has a fixed slope to correct for both terrestrial
and satellite band inputs. It also has gain and slope adjustment via switches for each band.
