stop level with the  
 and   recorder keys. It is advised to keep the stop 
level approximately three units above the actual audio level the CRQ is 
supposed to stop on. For the CRQ to actually stop recording the audio level 
needs to fall below the set stop level for a certain amount of time. This amount 
of time is called the Silence Period.

put on hold the audio level drops and the recording is possibly stopped, when 
the call resumes a new recording may start again. In order to keep the call in 
one recording a larger Silence Period is suggested. For the recording of radio 
communication it is preferred to keep the Silence period small to prevent 
consecutive communications in one recording.
