Run Listen Verify Diagnostic 
The Listen Verify diagnostic is used to determine if Base Stations are 
performing correctly. See SpectraLink 6300 MCU: Operator’s Console for 
details. When the test is run, each each Base Station stops transmitting 
for a short time and listens for other Base Stations.  The system checks 
signal strength levels between Base Stations to ensure that no Base 
Station is installed too close to another. If Base Stations are too close, 
one Base Station will be disabled (“locked out”) and an alarm will be 
activated, unless the Base Station in question has been designated as 
an “isolated” Base Station.  
Base Stations with diagnostic listen values of less than -40 dbm are 
close to being locked out. If the Base Station is only a few dbm away 
from locking out, it should be repositioned to get a lower signal 
strength to avoid the lockout.  
The Listen Verify test can be run manually or the system can 
automatically run it at the same time each day. See SpectraLink 6300 
MCU: Operator’s Console
 for detailed information on how to manually 
or automatically run the Listen Verify diagnostic, and how to 
interpret results.
