For Type A & B Projectors (PRM 10 and PRM 20), there are 2 filters to clean. DO NOT use canned/compressed air to clean the projector body. Dust does not need to forced into the projector components. Instead, remove each filter, use your breath to blow out visible dust, and return it to the same filter slot.
For Type C Projectors (PRM 30), there is one large filter on the back. Again, DO NOT spray canned air into the projector. Remove the sliding access door, rock the filter slightly to remove it, blow/wipe dust, and replace it. Remove it carefully, if you knock the projector out of alignment it may have to be readjusted.
If you need assistance, or prefer to have help, post to the SCSD Helpdesk and we will come onsite to show you the process.
