If you ever need to revert to factory settings, you can perform a factory reset. A factory rest will clear all setting and calibrations from the M1. Users should proceed with caution to ensure they want to reset everything before moving forward as setting can not be reverted once procedure is complete.
1) Holding down the Zero Button, turn on the M1. This should take approximately 10 seconds.
2) Factory Reset is displayed on screen
3) Tool is now factory reset.
