Frequently Asked Questions: Maintenance
How can I maximize my lamp life?
1. When you finish using the projector, let it run through its shutdown cycle before unplugging it (if needed). On this
projector, the fans continue to run after the projector shuts off the lamp. The fans are timed to run long enough for
the lamp to cool down before the projector is moved.
2. Keep the vents on the sides of the projector clear. Make sure to keep papers, books and other tabletop
paraphernalia away from the projector. Even partially blocking one vent disrupts the airflow enough to shorten the
life of the lamp and other internal parts.
3. Use your projector in as clean environment as possible. Polluted air can cause dust to build up on the vents, causing
the temperature to go up. This is especially true of ceiling mounted projectors.
4. Check and clean the dust filter at least every 250 hours of operation.
Is there software (firmware) for the projector that I should update?
The projector contains "flash" code that controls the startup process, the logo screen and so on. You can have an authorized
service center upgrade your projector's software, or you can do it yourself.
There are two reasons to 'flash' your projector. In very rare instances, software becomes corrupt and the projector does not
operate correctly. Reinstalling the code is one step in solving power and image issues. The second reason to take advantage
of updated code. Sometimes ASK Proxima updates the code to enhance features on the projector. Enhanced code may make
the picture better, or it might help keep the projector cooler.
To see which software version is on your projector, press the Menu button. In the Main menu, select About. The software
version appears in the About message box.
To check to see whether there is new software for your projector, check the Projector Software page for your model.
Are there air vents or filters on the projector that need to be cleaned?
The vents on the side of the projector by the lens are for air intake, and the vent on the opposite side is for hot air exhaust.
Unless the projector is operated in a very dusty environment, these vents should not need cleaning. However, when
mounting the projector, make sure to allow at least two feet of space between the vents and any walls. Also, it is very
important that the exhaust air is separate from the intake air. Don't put the whole projector in a big box without channeling
the two away from each other.
We recommend cleaning the dust filter on the projector every 250 hours. Click here for instructions on cleaning the dust
filter.
What is the expected life of the lamp?
The lamp life is approximately 2,000 hours. At 1950 hours, the Change Lamp message appears for 30 seconds on startup.
When the lamp use exceeds 2,000 hours, the lamp will not light. You need to replace the lamp and reset the lamp timer.
How do I determine the number lamp hours used?
Press the Menu button on the projector keypad. In the Main menu, select About. The number of lamp hours appears in the
About message box.
How do I reset the lamp timer?
Method 1: Turn the projector on. On the remote control, press the Volume – key. Within three seconds, press the Volume +
key. The LED on the projector will turn green and the lamp with light.
Method 2: Press the Menu button on the projector keypad. In the Main menu, select About. The number of lamp hours
