Important

When installing the projector, follow the warnings and cautions in the manual. Failure to observe this precaution could result in electric shock or injury.

If installing the projector on the ceiling, use only optional ceiling kits (two types) supplied by the manufacturer . Refer to the manual included with the optional ceiling kit for ceiling installation. When ordering the kit, specify the part name, PG CMKIT-F.

Installation

The Installation Set-Up Instruction chapter covers how to install the projector and gives you the details about the relative position of the projector and the screen. The Projection Configuration Change chapter gives you the procedures for adjustments such as image polarity change, proper adjustment of the focus rings and CRT angle adjustment. You must reconfigure the projector for your application when it differs from the factory setting.

INSTALLATION SET-UP INSTRUCTION.

Before Installation

The installation procedure is different according to the projection system and screen size. From the factory the projector is set for ceiling mount, 100 inch diagonal screen size and a projection angle of 12.4 degrees (XG85)/12.2 degrees (XG135LC). Installation and preliminary adjustments are required as shown on table below.

NOTE: For XG85, the “100 inch” covers the range of screen size between 80 and 129 inches. For XG135LC, The ''100 inch'' covers

the range of screen size between 90 and 109 inches.

NOTE: Focus ring adjustment on pages 15 and 16 for XG85, and 17 and 18 for XG135LC.

Carrying the Projector

WARNING:

Be sure to use the handles when carrying the projector.

Pulling Out the Handle

Pull out the handle from the bottom side.

Retracting the Handle

Press down the two levers at the same time to retract the handle.

INSTALLATION SET-UP INSTRUCTION

Note on Installation

CAUTION ON INSTALLATION

Position the projector according to the procedures specified in the following pages. Be sure to maintain the correct projection distance, direction and angle for optimum performance. Deviating from the correct installation could degrade the performance of the projector and may cause reliability problems.

WARNING:

Static displays that are left on for extended periods may cause CRT burns that are not covered under warranty.

For screen sizes other than 100", 120", and 180" diagonal, adjust the CRT angle using the threaded holes. See pages 16 and 18 for detailed procedures.

CAUTION ON ALIGNMENT ADJUSTMENT

The adjustment value of the items on the right must be within the recommended range of the values on the right. If it is hard or impossible to adjust the items on the right within the recommended range of values, the most probable cause of this is incorrect position of the projector. Check for correct projection distance, direction and angle, and reposition as recommended in this manual.

Ceiling Mount Projection Distance and Screen Size for XG85

•

Install in such a way that the projector and screen are positioned in the proper direction and at the proper angle. If not, the projector's performance will be affected and its reliability will decrease. Be sure to position the projector properly. The manufacturer will not be held responsible for any problems occurring when the projector is not installed in the proper position.

The following shows the proper relative positions of the projector and screen. Refer to the table to determine the position of installation

NOTE:

• For screens 150 inches (3810mm) or larger (in the diagonal direction), set so that the distance between the surface of installation of the mounting A and the ceiling is E.

• Set the projection distance based on the width of the screen.

• If the figures on the table do not match the figures in the formulae, use the figures on the table.

• For screen sizes of 60 to 300 inches not indicated on the table, use the following proportional formulae:

Units=inches W"=Screen H-Width

A = (25/962W"112.5)24.99`70.28 B = (β2A)`11.26 C = γ2A E = (1/22Screen Height)1B

Units=mm W"=Screen H-Width

A = (25/962W"112.5)2126.64`1785 B = (β2A)`286 C = γ2A E = (1/22Screen Height)1B

• The margin of error for projection distance (A) is53%.
