     Using the projector in a location that the altitude is too high or the ambient temperature is too high may reduce the life of the 

components or result in malfunctions.

  f  Use the adjustable feet only for the floor standing installation and for adjusting the angle. Using them for other purposes 

may damage the projector.

  f  When installing the projector with a method other than the floor installation using the adjustable feet, top placed on the 

floor, or the ceiling installation with the Ceiling Mount Bracket, use the five screw holes for ceiling mount to fix the projec-

tor to the mount.

    (Screw diameter: M6, tapping depth inside the projector: 12 mm (15/32"), torque: 4 ± 0.5 N·m)

  f   Do not install the projector in a confined space.

      When installing the projector in a confined space, provide air conditioning or ventilation separately. Exhaust heat may ac-

cumulate when the ventilation is not enough, triggering the protection circuit of the projector.

This projector supports AC 100 V to AC 240 V as the power supply. A grounded outlet supporting 15 A is required 

with either voltage.

The shape of the usable outlet differs depending on the power supply. Following illustrations are examples.

- 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. 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.
