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.
