Wireless Tips to Improve System Performance If you encounter wireless interference or dropouts, try the following suggestions: • Replace the transmitter batteries • Choose a different frequency channel • Reposition the antennas 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
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.
