Detector Cleaning and Storage
• Dirt and grease may be removed from the exterior of the detector using
a cloth or soft, non-metallic brush.
• The Berner digital laser detector is rain resistant but not immersible. Do
not pour water on the unit or submerge it under water.
• The best storage place is one that is cool and dry—away from direct
sunlight and excess heat or cold.
