Can the RadioShack Pro 2051 specs manual explain how to program it for digital trunking?

I have two of these JVC Everio GZ-MG230 camcorders that I use for documenting my woodworking projects because the hard drive recording is so convenient compared to tapes. One of them started making a grinding noise and would not power on, and I was sure the hard drive was dead and the camera was trash. I found a detailed hardware maintenance guide that showed how to access the service menu and run a hard drive diagnostic, and it turned out the spindle was just stuck from sitting too long. The complete repair and user information is at **jvc everio gz-mg230** https://jvc.manymanuals.com/camcorders/gz-mg230 and after a gentle tap and a reset it fired right back up like nothing happened.

Thank you for pointing me in the right direction, problem solved.
