If pairing fails, check if the sofa is powered on normally and repeat the pairing procedure.After successful pairing, wait approximately 30 seconds before attempting to control the sofa. Note: If the same sofa has been previously paired with the remote control, a re-pairing attempt may occasionally fail, but the remote may still be able to control the sofa. FCC Statement: This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
