Lens Shift Function - JVC DLA-M5000LE Manuel D'instructions

Lens Shift Function

Screen
90°
The separately sold lenses used on the projector have a lens shift function. With the lens used, you can adjust the projected
image vertically using the setting menu or the remote control's SHIFT button U or D.
When using the projectors in a stack configuration (stacked one over another), make adjustment so that the picture of one
projector overlays exactly that of another using the lens shift function.
For detailed adjustment procedures, refer to "Operating the Setting Menu" on page 29 and "Controls and Features" (page 10).
For maximum amount of shift, refer to "Maximum amount of shift" on page 16.
(When the lens needs to be adjusted in horizontal angles, consult your dealer or service center.)
Note
• Some of the lenses (except GL-M4023SZ and GL-M4015S) to be introduced in the future may not feature the lens shift
function.
Memo
Stack configuration:
Up to four projectors can be stacked and used together (stack configuration).
Using two or more projectors together, high image brightness can be attained. This allows you to project sufficiently bright
image in a fairly large auditorium or relatively bright place without using a heavy-duty projector.
CAUTION
• To prevent damage to the projector during shipment, a shift center lock pin was used to fix the lens mechanism when the
projector was shipped out the factory. If you implement "SHIFT LENS" on the setting menu and the lens does not either
move up or down, the shift center lock pin may not have been removed. Consult your dealer or service center.
CAUTIONS and NOTES
• When installing the screen, use a 4 : 3 aspect ratio picture. (A 16 : 9 aspect ratio picture is projected based on the width of
the range in which a 4 : 3 aspect ratio picture is projected.)
• The diagonal length of a 16 : 9 aspect ratio picture is about 91.8% that of a 4 : 3 aspect ratio picture. This value is a guide
and should be used as a reference.
• When projecting at the maximum projection distance, we recommend that the projector be used with the zoom on the Tele
(T).
• If sunlight or lamp light strikes the projection screen directly, the picture becomes whitish and dim. Be sure to use a
curtain, etc. to shield the light.
• Trapezoidal distortion may not be corrected.
Adjust the projector within the range of angle adjustment (up/down adjustment angle: +4°; horizontal adjustment angle:
±5°) so that it is set up level.
