Safety instructions
■Do not expose the amplifier to extreme temperatures.
■Place the amplifier in a dry and well-aired location.
■Install the unit on a vertical wall, or in a waterproof cabinet to a minimum IP55 rating, and
fix it safely using the special through holes supports.
Do not place the equipment where water can drip or splash onto it. Do not place objects
containing liquid, such as glasses, on the equipment. Do not place sources of naked flame,
such as burning candles, on the equipment. Do not block the ventilation slots of the equipment
with objects such as newspapers, curtains, etc. When installing the equipment, leave some
free space around it to provide adequate ventilation. Install the equipment in such a way that
the mains supply plug or the connector of the equipment can be easily reached.
IMPORTANT!
Use only the power pack supplied together with the amplifier. The use of other power
packs can cause malfunctioning and irreversible damages which will invalidate any
warranties.

Automatic channel research and memorization
AUTO-SCAN
The AUTO-SCAN function will scan the UHF band in input 1 and the BIII band in input 2.
The remote power is preset to OFF. It can be changed to ON in the INPUT V/U 1 and INPUT
V/U 2 menu. The remote power voltage is preset to 24V in the ADVANCED menu. The AUTO-
SCAN threshold is preset to 50dBµV in the ADVANCED menu. The LTE filter is preset to 5G
LTE700 in the ADVANCED menu.
To start the automatic programming, AUTO-SCAN, place
the pointer _below AUTO. Press
↵
to proceed. The
amplifier will start scanning the channels of the UHF band
on input [1] and the III band on input [2].
