Introduction The following is a general guideline to the best practice for projector maintenance and the advice will vary depending on the type of projector in question. Promethean strongly recommends that the projector user manual should always be consulted before any cleaning regimes are undertaken and / or changes are made to the projector, its settings or its components.
Projector Operation l amp mode: normal vs. high It is recommended that the projector is operated in a “Normal” mode rather than in a “High”1 mode as this typically meets most user needs. Instances where “High” mode may be necessary is where lights in the room cannot be switched off and therefore the ambient light “washes out” the projected image, or where the room is of an extremely large size such as 300 seat auditoriums.
Projector Environment A major determinant of a projector’s functionality and longevity is the environment within which it is situated. Averagely high dusty or humid environments can cause unseen damage to a projector if not regularly maintained and serviced. For example in dusty environments dust can settle both on the lamp and within the projector itself which can build up over time and cause both of these to overheat and thereby reduce their lifetimes.
ProjectorType Depending on the type of projector the customer has, the cleaning regimes and cleaning capability will vary. dlp projectors Typically, DLP projectors do not have air filters which need to be cleaned, but they do have air filters which can be purchased and fitted for environments and geographical territories which experience above average heat, humidity and / or high levels of dust. In these sorts of environments the fitted air filters will require frequent replacement by the customer.
ProjectorType Step 1: Press the MENU button to open the OSD menu. Step 2: Press the cursor button to move to the Installation II menu. Step 3: Press the cursor button to move up and down in the Installation II menu and select “Auto Power Off (min)” Press the cursor button to set the number of minutes before automatic shutdown of the lamp when no signal is detected. We suggest that the timer should be set for between 3 and 5 minutes.

Should the filter become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat build up and adversely affect the life of the projector. To maintain the life of the lamp, once the projector is turned on, wait at least five minutes before turning off.
ProjectorType PRM-20: This projector has 2 air filters and has a built in filter warning capability which can be set to OFF/100H/200H/300H. Promethean suggest that this should not be set to any more than 100H3 but as this is meant as a reminder only, Promethean strongly recommend that the filters be cleaned on a regular regime of every 30 days regardless of the hours used.
