If the solution posted by Susan R. (below) fails to work, locate the black power down box under the bed. Check the battery compartment and remove all batteries. If batteries are installed they will prevent a full reset of the box. Unplug the power cord, wait 45 seconds and plug the power cord back in to reset the electronic components. Replace batteries. Now that the error has been wiped from the box's memory, you can now synchronize your remote with the power down box using Susan's instructions below. - Mike V., Antioch, CA
"Locate the power down box for the bed and press the "learn button" for 1 second and release (Black box under the bed). On the hand control, simultaneously press and hold the position 1 and off buttons. The transmission indicator light will flash slowly and then flash rapidly. Continue to hold for 5 seconds and then release the buttons. It should now work! Enjoy. Susan R., Paducah, KY"
