Check the microphone to see if it is good by tapping it. The microphone
is located on the bottom plate of the unit.
5. Fixture Cleaning
The cleaning of external optical lenses must be carried out periodically to
optimize light output. Cleaning frequency depends on the environment in
which the fixture operates: damp, smoky or particularly dirty surrounding
can cause a greater accumulation of dirt on the unit’s optics.
Clean with a soft cloth using normal glass cleaning fluid or mild soapy water.
Always dry the parts carefully.
Clean the external optics at least every 20 days.
