Press the 'Enter' key ^:
Adjustment of Max Power.
Adjust the ALC 'MAX' trimmer on the rear panel in TX until the transceiver power
just starts to reduce. At this point readjust the 'MAX' trimmer in the opposite
direction to just above the point where the power starts to fall, so that the output
power is not affected.
Press 'Enter' .
^
Now adjust the ALC 'MIN' trimmer on the rear panel until there is no output from
the transceiver.
This sets the maximum ALC output voltage from the amplifier under fault
conditions, which will be used to reduce the input power to 0W.
When the power has been set to 0W Press 'Enter' .
^ The ALC is now set and you
will be returned to the menu list. You can now continue within the menu or exit by
any one of the 3 ways explained previously.
ALC Max trimmer—Clockwise rotation as seen from the rear panel reduces ALC
voltage so increases power—Anticlockwise increases ALC output voltage and so
reduces power.
ALC Min trimmer—Anticlockwise rotation reduces ALC voltage and so increases
power—Clockwise increases ALC voltage and so reduces power.
