Making adjustments (ET-WBC100)
After installing the wall mount bracket to the wall, adjust the projected image using the adjustment functions of the
wall mount bracket.
To perform forward/backward and vertical slide adjustment, you need to use a hex wrench or a ball point hex
screwdriver (diagonal 5 mm).
This wall mount bracket allows horizontal swing adjustment, vertical and horizontal tilt adjustment, as well as
forward/backward, vertical and horizontal slide adjustment of the projector.
z While referring to the operating instructions for the projector, project an image onto the screen and make a
rough adjustment of image size and focus. Then adjust projector installation angle and position, and make fine
adjustment of the image size.
z The projected image size can be adjusted by changing the distance between the screen and the projector.
Refer to "When adjusting the projected image size (forward/backward slide)" ( x page 16).
z Without applying any keystone correction in the [POSITION] menu of the projector, adjust the installation angle
so that all sides of the image are parallel with the sides of the screen. If the screen surface is not parallel to the
front side of the projector, keystone distortion will occur. Make adjustments while making sure that the projector
and screen face each other directly.
Attention
z Turning the knob beyond its adjustable range may damage the adjustable unit or cause the projector to fall.
■ When adjusting the projected image size (forward/backward slide)
Loosen two hex head bolts A or B (M4 × 6 mm) and pull out the arm to adjust the projected image

size.
z When roughly adjusting the projected image size for the first time after attaching the wall mount bracket
to the wall, calculate the value of L4 (distance from the wall surface to the center axis of horizontal swing
adjustment) in advance based on the value of L (projection distance) or L1 (distance from the screen
surface to the back surface of the projector) that corresponds to the image size to be used. For the
calculation formula of L4, refer to "Formulas for calculating dimensions" ( x page 9).
z Pull out the arm until the reading on the "POSITION" scale matches the calculated value of L4.
– If the calculated value of L4 is between 225 mm and 375 mm, loosen two hex head bolts A and pull
out only the first arm section.
– If the calculated value of L4 is between 375 mm (exclusive) and 495 mm, loosen two hex head bolts A
and two hex head bolts B. Pull out the first arm section to the end, and then the second arm section.
