Projector Usage Tips
Table of contents
Most projector components are very sensitive to shakes, squeezing and bumps, all of which may cause damage to the projector. The lamp in the projector is especially sensitive. When the projector is powered on, any movement can potentially cause harm to the lamp and may even lead to a projector crash. Avoid moving the projector as much as possible when it is powered on.
It is highly recommended that signal connections are not made while a projector is powered on (especially when connecting the VGA/D-sub port), this is because signal cables carry a current, and the sudden differences in electrical current may cause a projector lamp to burn out.
When the power-off button on the projector or the remote control is pressed, the image on the screen disappears, but it doesn’t mean that the projector has already stopped working. The projector lamp is usually still pretty hot, so the cooling fan will typically keep running for another 1 or 2 minutes to allow the lamp to cool. If the power is unplugged immediately after hitting the power off button, the fan will cease working which can do harm to the lamp and shorten its life. To avoid this, please do not unplug the power immediately after pressing the power-off button.
Projectors with high brightness output levels may come with an economy mode option to allow it to run at less than full brightness. For example, a projector capable of 3000 lumens may output only 2000 lumens when running in economy mode. The advantage of this is extended lamp service life. If that lamp is able to serve for 2000 hours when running at full brightness, economy mode may potentially extend that service life to 3000 hours. Therefore, if the workplace doesn’t require high brightness, it is preferred to run the projector at economy mode.
Like other electronic products, projectors also require suitable operating environments. The projector lamp produces a lot of heat which must be dissipated quickly during operation. Insufficient cooling can cause harm to the lamp, and may even cause it to fail. Therefore it is recommended that a projector is not used when temperatures are too hot or cold, which may have a negative affect as well. Generally a temperature range between 40ºF (5ºC) and 95ºF (35ºC) is recommended. Also avoid operating in excessively moist or dusty environements.
After a period of time, dust may accumulate on the lens and affect the quality of the image projected. Please clean the lens regularly using a purpose made piece of lens cleaning paper.
Most projectors have a filter to prevent dust from entering into the projector. However, dust can accumulate and block the filter after a period of usage. This causes a decrease in air flow moving through the projector and will reduce cooling efficiency. Therefore, periodic cleaning of the filter is necessary. Please consult the product manual for the recommended cleaning method.
Please store your projector away from places with extreme temperatures, moisture levels, or excessive dust. If the projector will not be used for an extended period of time, we recommended placing it back in its original packaging and storing it in a cool and dry place.
It typically takes a projector between 30 to 60 seconds to warm up after you connect the signal cable and start the unit. If there is no picture following the warm-up period, the most likely cause is the incorrect selection of the input signal source (DVD, computer, etc). At this time, it is necessary to select the correct source manually via the remote control or the buttons on the projector.
