If two or more accessories are paired to a single channel on your remote control you will need to re-pair the remote controller to the control unit.
First you will need to unpair the existing connection. To do this you need to press and hold the corresponding LED indicator on the control unit for the channel you wish to unpair for 7 seconds. The LED will begin to flash slowly. Continue to hold the button down until the LED flashes quickly. Once the LED is flashing quickly the connection has been unpaired. (Repeat this step for any additional channels you need to unpair)
After all channels are reset you can then re-pair each accessory individually. Remote Control Pairing Guide
