Put battery into the laser tube with the “+” outward, and don’t point the laser beam to anybody, especially the eyes.You shouldn't bump the machine. You shouldn’t disassemble or rebuild the machine, we will not responsible for the damage caused by this. The laser Pointer is quite sensitive to the temperature. The output power will vary when the temperature varied. It is better for lifetime of laser for using laser about less than 3 minutes.
