AssociationProcedure
The wireless controller will only function with the chair it has been “associated”
with. This prevents unwanted movement in locations with more than one chair.
Each wireless controller’s association is preset at the factory. This procedure is
only required in the event of a malfunction, if a new controller is purchased, or
ifyouareattemptingtousethecontrollerwithachairotherthentheoneitwas
originallyassociatedwith.
