Reducing IC28H power output
 

Hi all!
I would like to know the proceedings to reduce the maximum power
output of the ICOM IC28H transceiver. I know that it has two levels of
power output: 5W and 45W. I'd like to reduce the maximum power output
to 20W or 25W (22W would be the best!). Someone told me that this kind
of equipment has an internal adjustment for this kind of work.

Could anyone help me?
