12) Gradually turn the multifunction knob until you set the needed output power (clockwise to increase the value,


IMPORTANT: do not exceed the rated output powers (e.g.: 5000W with Archimede 5000, or 100% in Stand-by mode).

When setting output power with the equipment in normal operation (ON status), if the reflected power exceeds the set
value for the Archimede model, the system will release an alarm because of the excessive V.S.W.R. (Voltage Standing
Wave Ratio) (

Par.13.1) . In this case check the antenna system to reduce as much as possible the reflected power.

Warning: operation without antenna, or with a faulty antenna, may cause degradation and possible destruction of the
R.F. power stage. Such failures are not covered by our standard warranty.

Step 11 - the previous images refer to the first switch on with the equipment in stand-by mode. In this condition power value is
in percentage and referred to a logarithmic scale
– meaning, for example, that the setting 50 will be about ¾ of the rated power
level (e.g. 3750W with Archimede 5000). When the equipment is normally working, the SET For.Pow value will be given in W.
The forth row (Dir ....Ref) will also show the direct and reflected power levels in W.
