Images are fuzzy or out of focus

Interference or distortion appears in images

Check Remedy

Has the focus been adjusted correctly? Press the [Focus] buttons on either the remote control or the projector's control panel to adjust the

focus. sp.68

Is the lens cover still attached? Remove the lens cover. sp.6

Is the projector at the correct distance? The recommended projection distance range is 86–1473 cm (2.8–48.3 ft.). Set the projector up so

that it is within this range. sp.15

Is the keystone adjustment value too large? Decrease the projection angle to reduce the amount of keystone correction. sp.68

Has condensation formed on the lens? If the projector is suddenly taken from a cold environment to a warm environment or if sudden

ambient temperature changes occur, condensation may form on the surface of the lens, and this may

cause the images to appear fuzzy. Set the projector up in the room approximately one hour before it

is to be used. If condensation forms on the lens, turn the power off and wait for the condensation to

disappear.

Check Remedy

Are the image signal format settings correct? If a composite videog or S-Videog source is connected to the projector, use the "Video Signal"

menu command to select the signal format. s"Signal" - "Video Signal" p.81

Are the cables connected correctly? Check that all of the cables required for projection are securely connected. sp.19–p.31

Is an extension cable being used? If an extension cable is used, electrical interference may affect the signals. Use the accessory cables

and check if this helps.

Has the correct resolution been selected? Set the computer so that the signals that are output are compatible with this projector.

Have the "Sync.g" and "Trackingg" settings

been adjusted correctly?

adjustment, you can make the adjustments using the "Sync." and "Tracking" menus.
