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 (SW90) inside of the projector to de- tect the internal temperature rising abnormally.
Circuit Protections 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.
Maintenance Cleaning the Air Filter 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 Cover When moving the projector or while it is not in use, replace the lens cap. Thread the string through the hole on the lens cap and then tie a knot in the string to secure it in place. To pass the other end of the string into the hole on the top of the projector and pull at it.
Lamp Replacement Lamp replacement order rePlAceMeNt lAMP WArNING: type No. PoA-lMP131 - For continued safety, replace with a lamp assembly of the same Service Parts No. 610 343 2069 type. - Allow the projector to cool for at least 45 minutes before you open the Lamp Cover 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.
Standby mode Notice This function is available when operating the projector via network. Network..Supply the power to the network function even after turning off the projector. You can turn on/ off the projector via network, modify network environment, and receive an e-mail about projector status while the projector is powered off.
