Make sure the power to the fan has been turned off, preferably by turning off the correct circuit breaker.
The dip switches in the receiver are located
at the bottom of the receiver inside the switch
housing. To set the switches (to make sure they
match the dip switch settings in the remote/transmitter) in the receiver, remove the receiver from the switch housing by lifting the receiving device out of the switch housing. Set the switches in the same position as the switches in the transmitter. Then reassemble the switch housing, turn power on and test.
