[Motorola] CDM 1250 Power Control?

[Coote, Jay]

I have several VHF CDM1250s, Model AAM25KKD9AA2AN.
The power output in these is only adjustable to about 20-55 watts.
I need to adjust power to 5 watts in some channels.

Is this possible in some but not other CPS/Tuner versions?

Is there a way around the lower power limit?

Thanks
