Step 3

              Clean the lense
  • Take a microfiber cloth or any clean cloth which is lint-free
  • Wrap it around a flat screwdriver and soak it with high-percentage cleaning alcohol. I used 80% alcohol and it worked fine
  • Clean gently and carefully the lense
  • Turn the laser back to its standard position with the gearwheel
