can press the up to move the screen upward. If you press and let
go of either up or down button the motor will do a small jog in
that direction for finer adjustment of screen. Once desired
position is reached turn switch over press and hold down tactile
button until the LED on back of switch blinks red twice. The down

will turn off, the motor will return to run mode and no changes will
be saved. If this occurs, return to step 3 for down limit adjustment
or step 4 for up limit adjustment.

limit switch adjustments, EVEN if a third party control system is
used. Therefore, it is advised to wire the switch or provide a
3-conductor connection that is accessible.
