FAQ / 1 Series / X1 ERR Troubleshooting

X1 ERR issue troubleshooting

Overview

The X1 ERR condition should be handled as a structured hardware-plus-firmware check. Do not jump straight to repeated firmware updates until the mechanical checks are complete.

Applies to

X1

  1. Record the software version and serial number from Menu > System > Version and Menu > System > SN.
  2. Inspect the bottom-cover screws. A screw without the correct foot can create a short circuit.
  3. Check the sub-firmware version. If it reports 0.01, perform a factory reset and reboot.
  4. If the issue remains, run the firmware update twice, then factory reset and reboot again.
  5. Confirm the MCU/COM version matches the firmware branch you are loading.

Firmware mapping from the source guidance

  • MCU/COM V1.1 systems were paired with X1 firmware V1.56.
  • MCU/COM V1.2 or V1.3 systems were paired with X1 firmware V2.44.

Escalation point

  • If the mechanical check, firmware match, double update, reset, and reboot do not clear the issue, move the case to direct technical support rather than repeating the same cycle.
