Specification and setup are pretty similar to the Sony 1272/1252. You should be able to manage with a Sony manual if you have set up a CRT before. (Sony manuals are available on the Sony 125x/127x page of this web site).

Basic setup is like every other CRT projector. You have to place it the right distance from the screen. This is a trial and error task. Move the projector closer and farther away from the screen so that you use as much phosphor are as possible but make sure that active image doesn't go over tube edge. Leave about 3/8" of unused phosphor on each side. The manual doesn't help here as it suggests to place the projector farther than optimal and thus use smaller tube area. Focusing lenses is done as in every other CRT projector.

There are 3 sizes of spacers to install between tubes and lenses according to used image size: 60-79", 80-120" or 121-300" (diagonal sizes of a 4:3 screen). If you don't have spacers for your screen size you have to use washers as I don't know where to get these spacers*. I have the medium size spacers (80-120") in my projector. Tubes are toed-in horizontally for the same screen sizes with a couple of screws you see if you open the hood. All this is similar to Sony 125x/127x setup.

Setting geometry and convergence: First press the "test" button on your remote (projector cannot be set without remote). Every adjustment has to be done after you press test button. You should see a test pattern. Now just press the setting you want to adjust (for example Keystone) and then select the color (R, G or B) and do the adjustment using the arrow buttons (up, down, left, right) on your remote.

To reset all adjustments to midpoint (128) without resetting each one manually,  press: Test, Cut-off, 1, 5, 6, 5, Store, Store.  Don't mind about the "key not applicable" errors, just keep pressing the buttons.
