1. Safety Precautions
1.1. General Guidelines
-For continued safety, no modification of anycircuitmust be
attempted.
-Unplug the power cord from the power outlet before disassembling
thisprojector.
-Itisadvisableto use an isolation transformer inthe AC power line
before the service.
-Observe the original lead dress during the service. Ifashort circuit
isfound, replace all the parts overheated or damaged bythe short
circuit.
-After the service, all the protective devices such as insulation
barriers, insulation papers, shields, and isolation R-C
combinations must be properlyinstalled.
-After the service, check the leakage current to prevent the
customer from getting an electricshock.
1.2. Leakage Current Check
1. Prepare the measuring circuitas showninFig.1.
Besure to use avoltmeter having the performance described in
Table1. Fig. 1

2. Assemblethe circuitas showninFig. 2. Plug the power cord ina
power outlet.
3. Connect M1 to T1 according to Fig. 2and measure the voltage.
4. Change the connection of M1 from T1 to T2 and measure the
voltage again.
5. The voltmeter must read 0.375 Vor lower inboth of steps 3and 4.
Thismeans that the current must be 0.75 mAor less.
6. Ifthe reading isout of the above standard, the projector must be
repaired and rechecked before returning to the customer because
of apossibilityof an electricshock.
1.3. UVPrecaution and UHMLamp Precautions
-Besure to unplug the power cord from the power outlet when
replacing the lamp.
-Because the lamp reaches averyhigh temperature during its
operation, waituntil itcoolscompletelywhen replacing the Lamp
Unit.
-The lamp emits small amounts of UV-radiation, avoiddirect-eye
contact with the light.
-Because the high pressure lamp involves arisk of explosion, never
touch the lamp wire lead during the service. (See Fig. 3)
