pressing the button once each time allows the user to scroll through the  
functions or change a function. 

 
      The next screen is the audio (microphone/instrument) level (attenuator)   
      screen. Setting the levels correctly depends on the microphone or   
      instrument used and the person using the microphone. Setting the 
      attenuator to “0”db is the same as setting a control to maximum gain. 
      Setting the attenuator to –42 db is the same as setting a control to 
      minimum gain. Each step of the attenuator equals 3 db. 
 
      Setting the attenuator for the maximum Audio Meter reading on the  
      receiver without peak distortion will produce the best signal to noise  
      ratio.

       “Lo” for use with multiple frequency systems and the best battery life.
