Frequently Asked Questions: Maintenance

How can I maximize my lamp life?

• When you finish using the projector, let it run through its shutdown cycle before unplugging it. On many projectors, 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.

• Keep the vents on the sides, top and bottom 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.

• Clean the dust filter on the bottom of the projector every 200 hours. Filter cleaning instructions are available on the

ASK Proxima Website.

• Use your projector in as clean environment as possible. Polluted air can cause dust to build up on filters or vents, causing the temperature to go up. This is especially true of ceiling mounted projectors.

NOTE InFocus suggests that you unplug this projector when it is not in use. If the projector is ceiling mounted or in a rear projection setting, we suggest you use a separate wall switch or timer to ensure that the projector is completely powered down when not in use.

The LED on the projector keypad is red (or orange). No image may be projected. What is wrong?

This projector has a power button that lights and an alarm LED on the keypad. The power button shines green or orange, depending on the state of the projector. The Alarm LED is not lit under normal circumstances. Your User Guide contains information on LED status and behavior.

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 is to take advantage of updated code. Sometimes ASK Proxima updates the code to enhance features or source connectivity 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 Status. The software version appears in the Status message box.

To check to see whether there is new software for your projector, check the C90/C100 Software webpage.

Are there air vents or filters on the projector that need to be cleaned? How do I clean the dust filter.

This projector has a filter that prevents dust particles from getting inside the optics. It must be cleaned at least every 200 hours (more frequently, if the projector is operated in a dirty environment.

To clean the filter, do the following:

1.

Turn the projector upside down on soft surface.

2.

Extend the left elevator foot all the way.

3.

Loosen the screw that fastens the filter to the projector.

4.

Lift the filter out of the projector. You may need to gently pry the filter off.

5.

Clean the filter with a low powered vacuum. Also clean the vents on the bottom of the projector.

6.

Replace the filter and tighten screw. Retract the elevator foot.

NOTE Unless the projector is operated in a very dusty environment, the vents should not need cleaning. However, when mounting the projector, make sure to allow at least six inches 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.

What is the expected life of the lamp?

The lamp life is approximately 2,000 hours. When the lamp timer reaches 2,000 hours, the Alarm LED on the projector will light red, indicating that it is time to replace the lamp. This is a good time to replace the lamp and reset the lamp timer.

NOTE The expected lamp life is an approximation provide by the lamp manufacturer. Actual lamp life may vary depending on lamp usage, maintenance and manufacturing.

How do I determine the number of lamp hours used?

Press the Menu button, then navigate to Basic > Advanced > Service. Select Info. The number of lamp hours appears in the

Service Info window.

How do I reset the lamp timer?

In the menu of the projector, navigate to Basic > Advanced > Service. Select the Reset Lamp Timer option, and press the

Select button. When the Lamp Change window appears, click Select again to reset the timer. You can do this prior to 2,000 hours.

NOTE You must have a source hooked up to the projector when resetting the lamp timer. If you don't, the Reset Lamp

Timer setting is dimmed.
