How to fix Simrad Marine Equipment MX610/MX612 unit that fails to turn ON?
- B
  Brian ChavezSep 12, 2025
  To address a unit that fails to turn ON, ensure the power cable is properly connected to the back of the MX610/MX612 and that the 12-24 VDC power is active. Note that the unit typically requires about 30 seconds to reboot after power is reconnected. Also, inspect the power cable's in-line fuse (or circuit-breaker) and replace it if it's blown. Using a voltmeter, confirm that the 12-24 VDC supply is present on the power cable connector pins. If the issue persists, consider replacing the MX610/MX612 unit.
