ADJUSTING THE SCREEN EXTENSION
Yellow (do not adjust)
White (adjusts open screen position)
Figure 5. Limit switches
The extension and retraction limit switches have been preset at the factory. In general, we advise you to avoid readjusting these switches.
In rare cases, to enable proper alignment of the displayed image on the screen, you may need to adjust the extension of a screen. If adjustment to the extension is necessary, carefully follow these instructions. Keep in mind that incorrect adjustment can cause faulty operation.
Modifying the extension of the screen
It is possible to decrease the preset extension of a screen up to 3" (7.6 cm). Do not attempt to modify a screen extension more than this recommended amount. Do not increase the extension.
The limit switches are located on audience right of the case.
The white limit switch adjusts the extended (open) screen position.
The yellow limit switch adjusts the fully retracted (closed) position. Do not adjust this switch.
To decrease the screen extension:
1.Ensure that the screen is in its fully retracted position, but with the door open to access the limit switches.
2.Locate the white limit switch located on the audience right side of the case. Use a screwdriver to turn the switch in a clockwise direction.
Note: One complete turn of the switch will make approximately a 3/4" (2 cm) change in the screen’s stop position.
3.Activate the screen until it reaches the newly reduced stop position.
Once you have made the adjustment, whenever you extend the screen, it will automatically stop at the new position.
Caution
Improper adjustment of the limit switches can cause irreparable damage to a screen itself, resulting in voiding the factory warranty.
The yellow limit switch retracts the screen further into the case. Adjusting it is not advised.
Incorrect adjustment of the limit switch can cause the arms to lock.
Be sure the screen retracts fully or the door will close on it, and damage the screen.
