5.  Set up squelch settings. Controls are independent in UL (for each remote) and DL (master) bands. 

Typical values for UL are between -110dBm and -100dBm for squelch threshold. For DL, 
recommended value for squelch threshold is minimum level received in any active channel minus 
10dB.  

 

 

 

 

6.  Setup desired filter bandwidth, depending on presence of adjacent channels. In principle, 

recommended bandwidth filter is 90KHz due to its low delay, but if adjacent signal is detected, narrow 
filters can be used. Fine gain can be set to equalize input signals. 

 

Set Output attenuator

Check UL and DL gain for each remote
