[ICOM] Need Help w/PW-1 Problem

[Massimo 'Max' MUCCI - I8NHJ]

Ciao htankin
If you look at the leds stay on when the amp goes in
protected mode you can know the reason this happen.
Check the manual for the meaning of each lamps' combination.
This is the main starting point to understand the problem.
