WARNING ?Before caring, make sure the power switch is off and the
power cable is not plugged in, then allow the projector to cool sufficiently. The
care in a high temperature state of the projector could cause a burn and/or
malfunction to the projector.
?Use only the air filter of the specified type. Do not use the projector with the
air filter and filter cover removed.
?Avoid wetting the projector or inserting liquids in the projector. It could result
in a fire, an electric shock, and and/or malfunction to the projector.
CAUTION ?Please replace the air filter when it is damaged or too soiled,
and also when you replace the lamp.When the indicators or a message prompts you to clean the air filter, clean the air filter as soon as possible. If the air filter becomes clogged by dust or the like, internal temperatures rise and the power may be automatically turned off for malfunction prevention.
1. Turn the projector off, and unplug the power cord. Allow the projector to cool for at least 45 minutes and prepare a vacuum cleaner.
2. After making sure that the projector is cool adequately, slowly turn the projector so that the lens-side is facing up. Please be careful for a projector not to fall. While the projector is placed lens-side up, hold the projector.
3. Putting a finger on the filter cover's knob, slide the filter cover in the direction of the arrow to remove it.
4. Holding the air filter's knob, pull the air filter off.
5. Apply a vacuum cleaner to the vent of the projector for the air filter. And then slowly turn the projector bottom up.
6. Apply a vacuum cleaner to the air filter and filter cover.
Please replace the air filter when it is damaged or too soiled.
To prepare a new air filter, contact your dealer and tell the air filter type number = NJ09702.
An air filter of specified type will come even with the replacement lamp for this projector.
7. Position the cleaned air filter or a new air filter into place, and push the points
of "PUSH" word with claws to fix the air filter.
8. Replace the filter cover and snap it back into place.
9. Slowly turn the projector so that the top is facing up.
10. Turn the projector on, and reset the filter time using the FILTER TIME

or neglect of resetting after replacement) will result in incorrect message
functions.

It says to Check the air flow


Open the cover. At some ends there will be 'filters', to clean the air entering the projector. If these filters are blocked with dust or lint, air flow will be blocked.
Clean any dust from these filters. Close the cover and check whether your problem is solved.

I follow all the steps to reset the filter time and lamp time with a new bulb but it will not reset any ideas


This Projector is controlled by an internal microprocessor. Under certain exceptional circumstances, the projector may not operate correctly and the microprocessor will need to be reset. In such a case, please push the Restart switch by using a cocktail stick or similar and before turning on again, make the projector cool down at least 10 minutes without operating. Only push the Restart switch in these exceptional instances.

Problem with hitachi cp-RS55 multimedia projector sir


There is a menu item which has both the lamp hour reset and check air flow, etc. You must go into the menu and reset the air flow item. MAKE SURE YOU CLEAN THE DUST FILTER!! Heat is the number one killer of projectors and Hitachi's run "hot". I clean my projector once a week--Hey, I'm not rich. lol! Also, excessive heat will cause the lcd panels to fail prematurely and cause lots of other components to do the same.--Rick

Hitachi CP-x430 "Check air flow"


I have run in to this time and time again. This is why I like to keep things clean. take the bulb out and blow the unit out with air and make sure you wipe off what you can with Q-tips The blub allows air to flow thew the filament so what ever dust that might touch the fillament while its burning will burn at a higher temp. this will send and indication to the unit to send a message that says replace bulb soon and If there is not enough air flow it will say CHeck air flow take the fliter out and clean it with water dont replace it. IF you do just buy a carbon pad and cover the hole(not recomended foir those who are not handy) but keep things clean and it will save you $ in the long run. How many bulbs do you want to buy?

Resetting the air filter timer


If you do not have a remote here is how to reset the filter time. Use the "Menu" bottun to get the "easy menu" to display. Push the down arrow until you get to "Filter Time," then push and hold the RIGHT arrow to reset the filter time. DO NOT try to reset using the "Reset" option on the easy menu, it will not work.

CP-S335 popping noise when powering on


Hi Eva

A Projector does'nt like being switched on and off all the time , if you are going to watch a couple of movies - rather leave the machine running all the time - this will also help you to get more hours out of your lamp - and that's a promise.

As far as the noise is concerned - it is most probably just the machine that was not cooled down properly at that stage.

Check air flow


You need to clean the filters. When the filters collect alot of dust on them, they block the airflow to the internal parts of the projector and can cause the bulb to blow due to the temperature getting to hot.
