6. Maintenance
• Keep the detector, particularly the detecting window, clean. If unit
becomes dusty, use a clean cloth to gently wipe it clean.
• Avoid knocking the unit over or allowing it to fall on the ground.
• Although the detector is rain resistant, you should avoid
submerging the unit in water or other liquids. If unit comes into
contact with water or other liquids, wipe it dry immediately.
• Do not use unit around fire or expose it to fire in any way.
