Safety Instructions Safety Precautions WARNING: The chassis of this projector is isolated (COLD) from AC line by using the converter transformer. Primary side of the converter and lamp power supply unit circuit is connected to the AC line and it is hot, which hot circuit is identified with the line ( ) in the schematic diagram.
Specifications Mechanical Information Projector Type Multi-media Projector Dimensions (W x H x D) 1.1" x .5" x 9.7" (.5mm x 85.mm x 47 .0mm) (Not including protrusions) Net Weight 5.5 lbs (.5 kg) Foot Adjustment 0˚ to 10˚ Panel resolution LCD Panel System 0.55"...
Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the pro- jector, it will automatically turn off by operating one of the following protection circuits. Thermal switch There is the thermal switch (SW601) inside of the projector to de- tect the internal temperature rising abnormally.
Warning temperature and power failure protection The projector will be automatically turned off when the internal temperature of the projector is abnormally high, or the cooling fans stop spinning, or the power supplies in the projector are failed. - If the WARNING indicator is flashing, it may detect the abnormal temperature inside the projector. Check the follow- ing possible causes and wait until the POWER indicator stops flashing, and then try to turn on the projector.
Maintenance cleaning the Filters Filter prevents dust from accumulating on the optical elements inside the projector. Should the filters become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat buildup and adversely affect the life of the projector. If a “Filter warning” icon appears on the screen, clean the filters immediately.
Maintenance Attaching the lens cap When moving this projector or while not using it over an extended period of time, replace the lens cap. Attach the lens cap according to the following procedures. Thread the string through the hole on the lens cap and then tie a knot in the string to secure it in place.
Lamp Replacement Lamp replacement order rePlAceMeNt lAMP WArNING: type No. PoA-lMP132 - For continued safety, replace with a lamp assembly of the same Service Parts No. 610 345 2456 type. - Allow the projector to cool for at least 45 minutes before you open the lamp cover.
Lamp Replacement recommendation Should the air filter become clogged with dust particles, it will reduce the cooling fan’s effectiveness and may re- sult in internal heat build up and short lamp life. We recommend cleaning the air filter after the projection lamp is replaced.
Security Function Notice This projector provides security functions such as "Key lock", "PIN code lock" and "Logo PIN code lock". When the pro- jector has set these security function on, you are required to enter correct PIN code to use the projector. If you do not know the correct PIN code to the projector, the projector can no longer be operated or started.
