Single System Set Up 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. group (A-Y) 1. 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).
Multiple System Set Up 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. 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.
Tips to Improve Wireless System Performance If you encounter interference or dropouts, try the following suggestions: • Choose a different receiver channel • Reposition the receiver so there is nothing obstructing a line of sight to the transmitter (including the audience) • Avoid placing transmitter and receiver where metal or other dense materials may be present • Move the receiver to the top of the equipment rack • Remove nearby sources of wireless interference, such as cell phones, two-way radios, com
Batteries Expected life for AA batteries is up to 14 hours (total battery life varies depending upon battery type and manufacturer). When the LED indicator turns red, it signifies "low battery" with approximately 60 minutes of remaining battery life. For alkaline batteries only. For rechargeable batteries, solid red means the batteries are dead. To remove batteries from the handheld transmitter, push them out through the opening in the microphone battery compartment.
Rack-Mounting a Receiver Use the supplied mounting hardware to install the receiver in a standard 19" audio equipment rack.
