If the red led is lighting, then means that the approximate remaining work time is 

around 20 minutes. 

 

The decision to send the low battery message to the red light is taken by one of 

the inner microcontrollers. 

 

One ADC (Analog to Digital Converter) takes the battery voltage data and then 

the microcontroller takes the decision to turn on or not the red led. 

 
 

2.6 AUDIO LEVEL ADJUSTMENT 
 

 

The audio GAIN selector is a multi-position switch that provides audio level 

adjustments for a wide variety of audio sources. 

 

Its associated set of precision resistors allows the user to select gain preset 

ranging from MIC level sources to LINE level sources. 

 

This feature is very useful so that the user doesn’t need any type of external 

attenuator to accommodate any type of audio signal source to the equipment 

audio signal envelope. 

 

 
2.7 PEAK AUDIO INDICATOR 

 

When the red led is flashing, then the user is achieving the peak modulation 

deviation. 

 

This indicator is very usefully to adjust the GAIN pot in order to have the best 

signal to noise ratio (SNR). 

 

2.8 POWER SUPPLY 
 

The LIVE 20 TR is powered by an internal Lithium / Ion battery DR-202. Please 

never

 substitute this battery for any other or connect the equipment to any 

external feeder.
