I tried to change the remote codes on the fan and

When I changed the dip switches on the Hunter receiver, I noticed that the remote would not work when set to the new code. When I set it back to the previous code, it would work, leading me to determine that the receiver has some basic memory. The solution was to simply cut the power to the fan at the circuit breaker box and the new dip switch settings now work.
