M3 SURFACE TEMPERATURE TEST
Before you check the temperature, make sure the projector is in the full operating mode (wait about 20 minutes
after switching on the projector). Use a contact probe to measure the surface temperature on the projector’s metal
case and determine the hottest area at the bottom’s projector (nearest to the lamp). The temperature must be less
than 70°. Otherwise, check the cooling system.
M4 CLEANING
Cleaning must be carried out when the projector is cool disconnected from the power supply with the general
power switch turned off, and the ON/OFF switch on the rear panel switched OFF.
FREQUENCY
It is recommended to clean the projector every two months to ensure efficiency and performance. If the projector is
used in particularly smoky or dusty areas, clean the projector more frequently.
Cleaning Procedures
1 Open the top lid by unscrewing the knob and removing it from its seat.
2 Use a vacuum cleaner to remove dust.
3 Use a soft cloth (non fabric) and pH neutral (pH7 ) liquid detergent to clean mirror and lens surface. Make sure
you remove all residual traces. Never touch the lamp directly with your hands or materials that can leave greasy
traces.
4 Follow the same steps to clean the other internal parts of the projector.
5 Make sure the cleaning procedure did not damage any internal part or modified their correct position
6 Replace the top lid and firmly tighten the knob.
If the projector is operated in ordinary working conditions and the user follows the planned maintenance operations
established by the Manufacturer, it should last for three years
When the projector is discarded, it must be disposed of according to recycling laws.
