Cleaning the Air filter (continued)
3 | Clean the air filter with a vacuum cleaner |
4 | Install the air filter |
Caution When the air filter becomes clogged with dust, etc., the projector power may turn off to prevent the internal heat level rising. (The lamp indicator color changes to red.)
Do not operate the projector with the air filter removed. (If used with the air filter removed, dust can enter the LCD panel and produce an adverse effect on image quality.)
Lamp
The light source lamp has a service life.
When used for an extended time, the images may become darker and the colors may deteriorate.
A malfunction could occur if the projector is used in this condition, so replace the lamp with a new one. The indicator or message appears when the power is turned on, indicating that the lamp should be replaced.
At such time, it is necessary to replace the lamp with a new one. For lamp replacement, please contact
BOXLIGHT.
Caution | Even when the lamp is at a high temperature, the power to the projector may cut off to prevent | |
an excessive temperature increase inside the projector. (The POWER indicator turns off.) Turn | ||
| ||
| off the MAIN POWER switch, wait for some 20 minutes and turn on the MAIN POWER | |
| switch again. If the projector is not recovered after turning on the MAIN POWER switch, | |
| please contact BOXLIGHT. | |
