1.1 General Guidelines
TOP PREVIOUS NEXT
●For continued safety, no modification of any circuit must be attempted.
●Unplug the power cord from the power outlet before disassembling this projector.
●It is advisable to use an isolation transformer in the AC power line before the service.
●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.

1.2 Leakage Current Check
TOP PREVIOUS NEXT
1. Prepare the measuring circuit as shown in Fig.1.
Be sure to use a voltmeter having the performance described in Table 1.
Fig. 1
Table 1
Fig. 2
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 0.75 mA 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.

1.3 UV Precaution and UHM Lamp Precautions
TOP PREVIOUS NEXT
●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.
●Because the high pressure lamp involves a risk of explosion, never touch the lamp wire lead
during the service. (See Fig. 3)

2.1 Procedure to enter EXT OPTION
TOP PREVIOUS NEXT
1. Press "MENU" button on the main unit or remote control unit to display "MENU" screen, then
select "OPTION" and press "ENTER" button.
2. Select "OSD" on "OPTION" menu and press "ENTER" button 3 seconds or longer.

●FREEZE MSG
Switching ON/OFF "FREEZE" on-screen display
●PIC.SHIFT
Switching ON/OFF the antipersistence function
❍Shifts the picture slightly (by one dot) when every 60 minutes. (one dot shifting three
times, one dot shifting three times in reverse direction, and repeats them alternately.)
●RUNTIME PRT
Switching ON/OFF the shutdown when the operation time for the lamp unit is 2 000 hours or
longer
●FAN CONTROL
Setting the cooling fan motor rotation speed
❍Switching ON "FAN FULLMODE", the rotation level of the fan becomes high-speed
rotation (fixed). Moreover, when "FAN FULLMODE" is ON, changing "FAN
CONTROL" in OPTION becomes impossible (setting FAN FULLMODE is given
priority more than FANCONTROL).
●AUTOSETUP
Setting AUTO SETUP mode
