You'll know your shade is telescoping (tracking) whenever it's not going down straight. You will also be able to see a "cone" on one side, displayed below. It may move over to the left or right during operation.
This can occur from several factors; irregularities in the fabric, irregularities in the tube, unsquare windows, unlevel brackets. Telescoping isn't covered in the warranty - it can be fixed quickly on site. We recommend you shim any shades that are tracking during installation.
Roll the shade all the way down to its bottom limit. Put the shade in limit setting mode by holding the DOWN and STOP buttons at the same time for 5 seconds. This will allow you to roll the shade past its bottom limit.
Roll the shade down enough to expose the aluminum tube. You may already have stickers from the factory adjusting for fabric irregularities.
Shim the side that is coning. If your shade is moving over to the right, shim the left. If it moving to the left, shim the right. A sticker or tape (painters, scotch, etc.) works the best.
Roll the shade up to test for tracking. This can be done by holding the up button for a few seconds. It's important you stop the shade before it reaches the top, as it will not stop rolling.
Once the shade is tracking normally, move the shade to the desired bottom limit. Hold the DOWN and STOP button for two seconds to re-set the bottom limit - the motor will jog twice and beep three times.
