may collect some dirt or debris. This will affect beam quality and
operating range. the lens should be cleaned with a cotton swab
moistened with water as shown.

cloth such as a cotton cloth. USE WATER ONLY — DO NOT
use cleansers or solvents. Allow the unit to air dry before
storing.

the laser often. See the "Field Calibration Check" section of this
