The M7200 radio also provides audible Alert Tones or “beeps” to indicate the various operating 
conditions (see Table 7-3).

Grant (or Go-
Ahead) 

single short beep 

Sounds when resources become available for a call 
request placed in the queue (if enabled) upon channel 
access.  
If the radio roams to another site while transmitting, 
then it will auto rekey and begin transmitting on that 
tower. It gives a second grant tone to let the user 
know they have roamed.
