1, Adjustable focus: Rotate the laser head, can adjust the focal length;
2, The laser shell is high voltage, pay attention to insulation, otherwise it will damage the laser;
3, Do not look directly at the laser, the laser generated by the high power density laser beam, may cause unnecessary damage;
4, Laser is an ESD sensitive device. In the process of installation and use to prevent static electricity, so as not to damage the laser;
5, Products should be avoided in high temperature and high humidity environment, otherwise it will affect the service life. When not in use, disconnect the laser power and place it in a cool, dry place.
6, The red laser beam only can be seen in smoke enviroment, if you mind please choose green laser.
