Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the projec- tor, it will automatically turn off by operating one of the following protection circuits. Thermal switch There is the thermal switch (SW902) inside of the projector to detect 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. led indicator POWER indicator...
Maintenance Replace 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 filters immediately.
Maintenance Cleaning After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized glass, lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit. Remove dust and other particles using air spray.

Lamp Replacement How to check Lamp Used Time Projector used time The LAMP REPLACE indicator will light yellow when the total lamp used time (Corresponding Counter value) reaches 5,000 hours. This is to indicate Projector 650H that lamp replacement is required. Lamp You can check the lamp used time following Cumulative...
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".
