Hey everyone,

I’m troubleshooting a Motorola CDM1550 VHF 45-watt model, and I’m having trouble finding the correct service manual for it. I have the 220-700 MHz manual and one for the CDM1550 Professional model, but neither of them seems to match the board layout of the unit I’m working on. The schematics are similar, but the component placement is noticeably different.

It looks like the 45-watt version might be a different variant, and I’m wondering if anyone knows what it's officially called or has the correct manual that covers this specific model. Any help would be appreciated!

Thanks in advance!
