I recently went to clone a Motorola PM1500 Mobile Radio. It powered on fine. This radio is a high power, 110 watt, radio with remote head. Something happened during the cloning process and now when powering up the radio it will power cycle a few times showing FL 01-90 and then will finally power on reading Maintenance Mode Remote Device and/or Maintenance Mode Local Device. I have been programming and cloning the PM1500 via the mic port on the remote head with a Motorola OEM USB Cable. My experience with this error has always been a power supply issue to the radio itself. Once that is corrected the radio operates normally. I have successfully cloned this specific radio along with many other PM1500s using the same process multiple times in the past. When I connect my USB Programming Cable to the remote head the computer recognizes that it is connected however will not read/write/clone or even read the serial number.
So far these are the troubleshooting steps I have tried.
Anyone have any other suggestions or recommendations?
So far these are the troubleshooting steps I have tried.
- Checked all fuses on both the radio and remote head.
- Checked voltage on all power supplies.
- Check continuity between pins on data cable between remote head and radio.
- Swapped remote heads with a known good PM1500 radio and got the same results with the known good head.
- Power up radio prior to applying power to the remote head.
- Using different data cable ports on the radio and remote head.
Anyone have any other suggestions or recommendations?
