Cleaning Instructions
Lattice and base
Turn off the detection system prior to using liquid cleaners. Remove dirt and greasy buildup using towels or soft cloths that
have been dampened with a common household grease-cutting liquid cleaner. 3M suggests a monthly cleaning to retain the
best equipment appearance.
Photocell lens and reflector
At least once a month, wipe the photocell lens and reflector with a soft cloth dampened with water.
