Safety Instructions
1. Safety Precautions
  1.1. General Guidelines
  1.2. Leakage Current Check
1. Prepare the measuring circuit as shown in Fig.1.
    Be sure to use a voltmeter having the performance described in Table 1.
2. Assemble the circuit as shown in Fig. 2. Plug the power cord in a power outlet.
3. Connect M1 to T1 according to Fig. 2 and 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 V or lower in both of steps 3 and 4.(This means that the current must be 0.75mA or less)
6. If the reading is out of the above standard, the projector must be repaired and rechecked before returning to the customer
    because of a possibility of an electric shock.
- For continued safety, no modification of any circuit must be attempted.
- Unplug the power cord from the power outlet before disassembling this projector.
- Use correctly the supplied power cord and must ground it.
- It is advisable to use an isolation transformer in the AC power line before the service.
- Be careful not to touch the rotation part (cooling fan, etc.) of this projector when you service with the upper
  case removed and the power supply turned ON.
- Observe the original lead dress during the service. If a short circuit is found, replace all the parts overheated
  or damaged by the short circuit.
- After the service, all the protective devices such as insulation barriers, insulation papers, shields, and isolation
  R-C combinations must be properly installed.
- After the service, check the leakage current to prevent the customer from getting an electric shock.

  1.3. UV Precaution and UHM Lamp Precautions
- Be sure to unplug the power cord from the power outlet when replacing the lamp.
- Because the lamp reaches a very high temperature during its operation, wait until it cools completely when replacing
  the Lamp Unit.
- The lamp emits small amounts of UV-radiation, avoid direct-eye contact with the light.
- The lamp unit has high internal pressure. If improperly handled, explosion might result.
- Because the high pressure lamp involves a risk of failure, never touch the lamp wire lead during the service.

Lamp cover switch (SW901)
The lamp cover switch (SW901) cuts off the drive signal to the lamp 
circuit when the lamp cover is removed or not closed completely. 
After opening the lamp cover for replacing the lamp assy, place the 
lamp cover correctly otherwise the projector can not turn on.
Thermal fuse (SW902)
There is a thermal fuse (SW902) inside of the projector to detect the 
internal temperature rising abnormally. When the internal tempera-
ture around lamp reaches near 113˚C, the thermal fuse will open to 
cut off the power supply to the lamp power circuit.
If the thermal fuse opens, the projector cannot turn on. Thermal 
fuse replacement is required.
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
(F601)
Circuit Protections
Fuse (F601)
A fuse is located inside of the projector. When the 
ON(G)/STANDBY(R) indicator is not lighting, the 
fuse  may  be  opened.  Check  the  fuse  as  following 
steps.
The fuse should be used with the following type;
Fuse Part No.: 423 035 3004
TYPE T8AH 250V FUSE
LITTEL FUSE INC. TYPE 0215008.MXEP
How to replace the fuse
1.  The fuse is placed on the AC 1st filter board. 
  Remove the cabinet top, MAIN&AV board 
  following the "Mechanical Disassembly".
2.  Take the fuse off, and replace the old 
  one with the specified type.
