For rechargeable batteries, solid red means the batteries are dead. Before you begin, turn off all transmitters and turn on any equipment (other microphones or personal monitoring systems) that could cause interference during the performance. 1. Press and release the group button on the receiver. The receiver scans for the clearest group and proceeds to channel scan. Note: If you want to stop the scan, push the group or channel button. 2. Turn on transmitter and change the group and channel to match the receiver (See Manually Setting Group and Channel). Once the receiver is set up, perform an audio check on the microphone. Manually Setting Group and Channel Single System Setup Receiver Setup Group (letter) 1. Hold the group button on the receiver until the display begins to flash. 2. While the display is flashing, press the group button again to advance to the next group. Note: Only the group setting will be dis- played during the manual setup. 3. Once the desired group is reached, release the group button. Then the receiver will au- tomatically perform a channel scan. Channel (number) If channel needs to be changed, follow the same procedure using the channel button instead of the group button. groupchannel channel group group channel channel channel group group channel group group channel channel channel group group 4 Transmitter Setup Transmitter group and channel must be manually set to match the receiver. Group (letter) 1. Press and release the group button on the transmitter to activate the display. Press the group button again and the display flashes. 2. While the display is flashing, press the group button again to advance to the desired group setting. Channel (number) If channel needs to be changed, follow the same procedure using the channel button instead of the group button. Note: When the group and channel correctly match the receiver, the ready LED on receiver illuminates. 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 is 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. Turn on any other equipment that could cause interference during the performance so it will be detected during the group and channel scans in the following steps. Before you begin system set up, turn all receivers ON and all transmitters OFF. For the first receiver: 1. Perform a group scan. This finds the group with the most clear channels. Note: For the BLX88, the group scan sets up both receivers at the same time. 2. Turn on the first transmitter and change the group and channel to match receiver. 3. Leave the transmitter on and continue with the additional systems. For each additional receiver: 1. Use manual setup to change the receiver to match the group setting of the first receiver. Recall that each time the group setting is changed, a channel scan is automatically done. 2. Turn on the transmitter and ch…
