Press and release the group button on the receiver. The receiver scans for the clearest group and channel. Note: If you want to stop the scan, push the group button again. 2. Turn on transmitter and change the group and channel to match the receiver (See Setting Transmitter Group and Channel).
Shure Incorporated Multiple System Setup Up to 12 systems can operate simultaneously (band and RF environment dependent). Important: Set up each system one-at-a-time. Once a receiver and transmitter are tuned to the same group and channel, leave the transmitter powered on. Otherwise, scans from the other receivers will not detect that channel as occupied. For the BLX88, be sure to setup both transmitters before progressing to the next receiver.
