The receiver is located in the canopy that covers the hanger bracket attached to the ceiling. To change the settings of the switches you are required to disconnect power from the receiver/fan (switch off breaker). The position of the 4 dipswitches on the receiver have to correspond with the ones in the remote (open battery cover), which can be 16 different combinations. You will solve the problem faster if you check what the position of the dipswitches in the receiver is set to. You do not necessarily have to change it, unless you have second fan nearby with remote that uses the same dipswitch combination. If not, just check the poisition and make sure the position in the remote corresponds to that of the receiver. Flipping through all of the 16 combinations will be tedious since you are required to disconnect power every time you change the combination in the receiver or remote or both. The power disconnect is required for the receiver to reset to the new frequency when power returns to it. Hope this helps.
