■ 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. ● Fuse Fuse A fuse is located inside of the projector. When the POWER indica- tor is not lightning, the fuse may be opened.
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.
■ Lamp Replacement WARNING: ORDER REPLACEMENT LAMP - For continued safety, replace with a lamp assembly of the same Type No. Service Parts No. type. POA-LMP55 610 309 2706 - Allow the projector to cool for at least 45 minutes before you open the lamp cover.
■ Mechanical Disassemblies Mechanical disassemble should be made following procedures in numerical order. Following steps show the basic procedures, therefore unnecessary step may be ignored. Caution: The parts and screws should be placed exactly the same position as the original otherwise it may cause loss of performance and product safety.

■ Adjustments ● Turning On the Projector If the PIN code is set on the projector, you cannot start operating the projector. The PIN code can be reset to the fac- tory default setting (1234) according to the following procedure. When you reset the PIN code, the Logo PIN code and key lock will be reset, as well.
■ Optical Adjustments Before taking optical adjustments below, remove the Cabinet Top following to the “Mechanical Disassemblies”. When you adjust Integrator lens or Relay lens adjustment, you need to disconnect FPC cables of LCD panels on the main board. Optical adjustment requires a 2.0mm hex wrench and a slot screwdriver. Note: Do not disconnect connectors on the main board, because the projector cannot turn on due to operate the power failure protection.
