Here is the troubleshooting guide for the LaserPecker LP3 blinking red and green light.
1. Preparation
LP3 Laser Unit, rubber suction cup*1, thin insulate rubber tape (1mm) *1/scotch tape *1, H3 wrench*1, ruler*1, thin knife*1/ tweezers*1
2. Detailed steps
(1) Use a thin knife or tweezers to peel off the black patch on the handle. (Please be careful when using the knife.)
(2) Unscrew the screw inside the handle using an H3 wrench.
(3) Use the suction cup to lift the Laser Unit cover plate, then use a ruler to fully open it. (Do not force it open, as this may deform the plate.)
(4) Cut two washers from the thin rubber insulating tape or tape, then glue them to the back of the two touch buttons.
(5) Reassemble the cover plate, handle, and black patch as originally installed. You have now completed all the necessary steps.
