Radius CP50 - can't locate R417 jumper for removal.

Hi all,

I'm working with a Radius CP50 and I've found the information about needing to remove the jumper R417 for full unlocking of keypad. I even tracked down the schematics which show the location on a VHF model.

When I opened up the CP50 UHF, I noticed my board is different.

Does anyone know where it would be located on my UHF model?

Hello
Just what im seeing and offering an answer for your consideration.
Ive many times seen the jumper locations in various Motorola radios and always the jumper was just a zero value pc that did nothing more than close the circuit or open it ect .
When Motorola installed a jumper it was a small green chip that did nothing other than close the circuit which heck you could do with a wire soldered across connections and close the jumper or remove it and its open not jumpered.
And i do see a green zero value jumper pretty dang close to same area of the vhf diagram you posted versus your radios.
Motorola was famous for revision A the Revision B and so on so MAYBE ?????
