Modifying the extension of the screen and the mask

You can increase the extension of the screen and mask 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 9.

To increase the screen's fully extended (screen down) stop position:

1.Lower the screen or mask to its current stop position.

2.Locate the white extension (down) limit switch located on the left side of the screen tube. Use a screwdriver to 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 or mask’s stop position.

To decrease the screen extension:

1.Lower the screen or mask 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 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 or mask'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 or mask, 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.
