When operating the blind with the TTU programming unit you must always press and hold command buttons to make it move, even after limits are set
When no limits are set, the blind will jolt twice before moving when pressing and holding one of the command buttons
When one limit is set, the blind will jolt once before moving when pressing and holding one of the command buttons
After an obstacle has been detected you will need to run the blind away from the obstacle before you can continue in the original direction of travel
If the blind unexpectedly stops during travel it may be caused by the obstacle detection function detecting extra resistance. This can be caused by the blind being fitted out of the square or in the case of a zip blind, something in the channels
