Maintenance and Care
Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter becomes clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat buildup and adversely affect the life of the projector.
If the projector reaches a time set in the timer setting (p.62), a Filter warning icon (Fig.1) appears on the screen and the WARNING FILTER indicator on the top panel lights up (p.78). When you see this icon, replace the filter cartridge as soon as possible (pp.30, 56). All the indicators except Lamp indicator blink fast when the projector detects an abnormal condition, or the filter cartridge is not installed properly (p.78).

PNote:
•Fig.1 will not appear when the Display function is set to Off (p.52), or during “Freeze” (p.30) or “No show” (p 29).
•The filter cartridge is disposable. Do not clean and reuse the filter cartridge.
•Do not expose the filter cartridge to water or liquid, or it may cause a breakdown.
•Do not use the filter cartridge with other projector.
•Make sure that the projection lamp is turn off when you are replacing the filter cartridge. If you replace the filter cartridge when the projection lamp is turn on, the projector will be shut down automatically for safety purpose.
