							Adjusting the Projected Image
Adjusting the Angle of the Projection
If the height of the projected image does not fit the screen, you can adjust the angle of the projection
using the adjustable feet.
1. Lift the projector.
2. Adjust the length of the adjustable feet.
Adjust the height of the right and left adjustable feet so the projector is level. If the projector is
inclined too much, an error occurs and operation cannot be performed. • You do not need to adjust the angle of projection using the adjustable feet if the projector is
installed on a wall or ceiling.
• The projector automatically adjusts the projected image for keystone distortion according to the
projection angle. If [Auto Keystone] in [Display/Sound Settings] is specified as [Off], manually
adjust for keystone distortion. For details, see page 40 "Adjusting for Keystone Distortion".

distortion.
If [Auto Keystone] in [Display/Sound Settings] is specified as [On], the projector automatically adjusts
the projected image for keystone distortion according to the projection angle. If this setting is specified
as [Off], adjust for keystone distortion using the following procedure.
