VARIABLE GAIN ADJUSTMENT AND LED INDICATORS 

 
 

  AC Power LED - Illuminates when the AC voltage is supplied, the unit is ON, and the 

AC/DC power supply is operating. 

  DL ALC LED - Illuminates when DL composite power reaches the ALC set 

  DL  Alarm -  Illuminates when the DL amplifier fails. 

  UL ALC LED - Illuminates when UL composite power reaches the ALC set. 

  UL Alarm - Illuminates when the UL amplifier fails. 

  External DC LED (optional) - Illuminates when the BDA is operating from a DC source. 

  Oscillation detection LED (optional) - Illuminates when oscillation is detected.  

  Donor antenna alarm LED (optional) - Illuminates when Donor Antenna is disconnected.  

  Mobile antenna alarm LED (optional) - Illuminates when the mobile port is disconnected.  

  DL Manual Gain Attenuator- Is a switch used  for DL gain attenuation  

  UL Manual Gain Attenuator- Is a switch used  for UL gain attenuation
