Use and maintenance manual
First of all thank you for choosing an product.
products are solid state or thermionic tube transmitters that develop power
from a minimum of 20W to a maximum of 30KW.
Great care has been taken during the design of the protection circuitry to ensure compa-
tibility with products from other manufacturers. However the best performance is achieved
when the equipment is used with other products manufactured by .
The unit has been designed to guarantee stable performances over time, without the need
of special maintenance, minimised to a functional fans-check.
Operation of the unit is very easy and intuitive. Even so it is recommended that this manual
and other relevant documentation is read carefully before any operation.
Dear User,

2. USAGE INSTRUCTION
ELENOS
Connected a 50 load or 50 antenna to the RF output, connect the
equipment into a mains supply (100÷240 VAC) with earth point. The
transmitter equipment is factory pre-set to 0.0 W.
Switch ON the power switch and the yellow V POWER led will light.
The Display will show:
After 3 seconds the green PLL LOCK led will light and the Display will
show an increasing bar, after a further 5 seconds the green ON AIR led
will light and there will be output power.
At this point the Display will show the next parameter for the transmitter:
•Level Modulation (MOD > );
•Forward Power (FRW 5.0W);
•Reflected Power (RFL 0.1W);
instead for the receiver:
•Level Modulation (MOD > );
•Level Signal(50dBuV).
