PM5 Troubleshooting

USB Overload Error


  • You have nothing plugged into the USB flash drive port on your PM5, and the PM5 has displayed a "USB Overload" error.
  • You receive a "USB Overload" error when you have inserted a USB flash drive that has either worked in other PM5s before or is a USB flash drive that you believe should work in the PM5.


  1. Upgrade your PM5 to Firmware Version 22/722 or higher and try again.
  2. If the problem persists, replace the batteries in the PM5.
  3. If the problem persists after attempting the first two resolutions, please contact us for further assistance.
