Question about Radio Communications

Installation I just installed a Motorola M1225 mobile radio and it does not power up. I tried another radio that I had and no luck. I have power to the unit. Isn't it as easy as power, ground and an antenna? Please Help.

Hello chiefcso54,

Most mobile radios need only a power connection and an antenna. If neither of the two radios you tried are actually powering up, you will want to check to make sure you actually have power at the power connector.

You should see approx 12 VDC using a voltmeter at the power connector. If you don't then check your installation, make sure you don't have any blown fuses, etc.

Ideally you want the power lines for the radio to connect directly to the automobile battery. If you are getting power from somewhere else in the car's electrical system then you may actually need to have the car running (or the key turned to the ON position) for the radio to get power.

If you have power at the connector and the radio still won't turn on then you might have a problem with the radio itself.

Hope that helps,

How do I down load users manual

I am surprised by how hard this is to find. My old links are gone, Motorola Solutions did not bother to carry the links over. So, the manual is very similar to the P1225 and the M1225 (mobile), the LS adds the Trunking features. Nothing is user programmable. The buttons on the front must be programmed by the dealer to do anything, but were usually a direct channel and resume (back to trunked operation). To make any changes, you need the Motorola software, cable and RIB (radio interface box). Parts are still available. They were rugged, good radios we sold hundreds of.

You have a corrupted codeplug, most likely. The radio will needed to be serviced by Motorola or a service facility with the ability to wipe the radio and reinstall the firmware and codeplug.
