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
