Technology 
  - Today       there are motorized lifting systems available for some window covering       products.  These systems use a       remote control and can be battery operated or hard wired.
- Motorized       shadings, shades and blinds are designed for ease of operation and       precise control. 
- With       remote-control units, operating functions are served by a hand-held       remote transmitter and a remote receiver mounted near the covering. A       single remote transmitter can operate up to 12 treatments. With       switch-control motorized units, a three-position switch is used to       operate each window treatment.
- The       lower travel limits of motorized window treatments are pre-set at the       factory. Buttons on the motor assembly provide for adjustment of the       lower travel limit after installation, if necessary.
- Upper       travel limits of motorized window treatments are controlled by a stall       sensor unit. The sensor prevents the motor from continuing to run after       the treatment is fully raised.
- There is one stall sensor unit for each treatment. It is located next to the control unit (remote control) or on the back of the switch plate (switch control).
