I have some motorized blinds in my home.  Zigbee AM43 is the type.  Occasionally, I need to reset the upper/lower limits.  The manual is located at: R:\Manuals\Household\Home Automation and the process is:

Upper Limit Setting:
Hit the setting button for 3 seconds - Indicator turns red
Press the Up button - Red indicator flashes quickly
Move the blind to the desired position
Hit the setting button for 3 seconds - Blue indicator flashes 3 times

Lower Limit Setting:

Hit the setting button for 3 seconds - Indicator turns red
Press the Down button - Red indicator flashes quickly
Move the blind to the desired position
Hit the setting button for 3 seconds - Blue indicator flashes 3 times
