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.
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 replacing the Filters Filter prevents dust from accumulating on the optical elements inside the projector. Should the Filter 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, replace the Filter 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 WArNING: order rePlAceMeNt lAMP - For continued safety, replace with a lamp assembly of the same type No. PoA-lMP142 type. Service Parts No. 610 349 7518 - Allow the projector to cool for at least 45 minutes before you open the lamp cover.
Lamp Replacement Resetting the Lamp Counter lamp counter reset Be sure to reset the Lamp replacement counter after the lamp is replaced. Press the Point buttons to choose the Lamp counter function and then press the Point SELECT button to 8 or the access the submenu items.
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 projector provides 2 types of standby mode, Eco standby and Network standby. According to the standby mode "Eco" or "Network", several functions are restricted as shown in the table below. To change the standby mode, use the projector's menu "Setting".
