     The geometric adjustment function cannot be used when the video signal in simultaneous format is input. When installing 

the projector, follow the instructions below so that distortion does not occur in the projected image.

 

f

 Use a flat screen.

 

f

 Install the projector so that the front side of the projector is parallel to the screen.

 

f

 Install the projector so that the image can be projected within the lens shift adjustment range.

f

  Install the projector in a place or with a mount that can sufficiently tolerate the weight. The position of the projected image 

may shift if the strength is not sufficient.

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

  The adjustable feet can be removed if not needed in the installation. However, do not use the screw holes where the ad-

justable feet were removed to fix the projector to a mount.

    Also, do not attach any screws not instructed in the operating instructions of the optional accessories into the screw holes 

where the adjustable feet are removed. Doing so may damage the projector.

f

  When using the projector in any method other than the floor installation using the adjustable feet or ceiling mounting instal-

lation using the Ceiling Mount Bracket, remove the four adjustable feet and use the six screw holes to fix the projector to a 

mount.

f

  Use a torque screwdriver or Allen torque wrench to tighten the fixing screws to their specified tightening torques.

   Do not use electric screwdrivers or impact screwdrivers.

   (Screw diameter: M6, tapping depth inside the projector: 27 mm (1-1/16"), screw tightening 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 AC100 V to AC120 V, and AC 200 V to AC 240 V as the power supply. A grounding 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.

f

Use the supplied power cord and ground at the outlet.

 

f

Use the power cord matching the used power supply voltage and outlet shape.

f

  The light output will decrease to approximately 1/2 when using the projector with AC 100 V to AC 120 V. 

f

  The supplied power cords vary depending on the country or region where you purchased the product.

- 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.
