1. Safety Precautions
1.1. General Guidelines
- 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 combi-
nations 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
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.

*1 Measurement, measuring conditions, and method of notation all comply with ISO/IEC 21118:2012 international standards.
*2 The value of the light output at the center region of the projected image is extracted based on the light output measurement method defined by the
ISO/IEC 21118:2012 international standards.
*3 Average value. Weight varies for each product.
*4 The operating environment temperature should be between 0 °C (32 °F) and 40 °C (104 °F) if the projector is used at an altitude between 1 400 m
(4 593') and 4 200 m (13 780') above sea level. When the [PROJECTOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE] is set
to [ECO], [SILENT], [LONG LIFE1], [LONG LIFE2], or [LONG LIFE3], the projector cannot be used at an altitude of 2 700 m (8 858') or higher above
sea level.
When using the projector at an altitude lower than 2 700 m (8 858') above sea level, and the operating environment temperature becomes 35 °C
(95 °F) or higher, the light output may be reduced to protect the projector. When using the projector at an altitude between 2 700 m (8 858') and
4 200 m (13 780'), and the operating environment temperature becomes 25 °C (77 °F) or higher, the light output may be reduced to protect the
projector.
