Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the projector, 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. When the internal temperature reaches near 105˚C, the thermal switch opens to stop the operation of the power supply circuit.
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. Check the following possible causes and wait until the WARNING indicator stops flashing, and then try to turn on the projector.
Security Function Notice Security Function Disable This projector provides security functions such as "PIN code lock" and "Logo PIN code lock". When the projector 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. In this case, you must reset those function first according to the resetting procedure described below and then check up on the projector.
Lamp Replacement Lamp replacement WARNING: - For continued safety, replace with a lamp assembly of the same type. - Allow the projector to cool for at least 45 minutes before you open the lamp cover. The inside of the projector can become very hot. - Do not drop the lamp module or touch the glass bulb! The glass can shatter and cause injury. ORDER REPLACEMENT LAMP Type No. Service Parts No. POA-LMP126 610 340 8569 Lamp Cover Screw Procedure 1 Turn off the projector and disconnect the AC cord.

KJ7-1000 Note on Soldering Do not use solder containing lead. This product has been manufactured using lead-free solder in order to help preserve the environment. Because of this, be sure to use lead-free solder when carrying out repair work, and never use solder containing lead. Lead-free solder has a melting point that is 30–40 °C (86–104 °F) higher than solder containing lead, and moreover it does not contain lead which attaches easily to other metals.
