Modifying the extension of the screen
You can increase the extension of the screen up to 3" (7.6 cm) past the
factory preset stop, or you can decrease the extension by approximately
4-6" (10 - 15 cm) from the factory preset stop. Do not attempt to modify the
screen extension beyond these recommended amounts.
The limit switches are located on the left side of the screen roller tube inside
the case, as shown in Figure 10.
To increase the screen's fully extended (screen down) stop position:
1. Lower the screen to its current stop position.
2. Locate the white extension (down) limit switch located on the left
side of the screen tube. Use a hex head or an electrician’s style
screwdriver (with a minimum 6-inch / 15 cm blade). Turn the
switch in a counterclockwise direction. If the power is on, the
screen will drop incrementally as the switch is turned.
Note: One complete turn of the switch will make approximately a
3/4" (2 cm) change in the screen's stop position.
To decrease the screen extension:
1. Lower the screen until it is extended about halfway down.
2. Locate the white extension (down) limit switch located on the left
side of the screen tube. Use a hex head or an electrician’s style
screwdriver (with a minimum 6-inch / 15 cm blade). 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 in the down direction until it reaches the
newly reduced stop position. Repeat this procedure until the
desired stop position is reached.
Once you have made the adjustment, whenever you lower the screen, it will
automatically stop at the new position.
Note: It is recommended that you make a note of any changes made to the
factory preset.
