If the radio you are calling sends back an automatic DSC
response of “able to comply,” the individual alarm will sound. 
Wait for a voice message from the called station.
If the called radio does not send an “able to comply”
response, your radio will wait eight (8) seconds and 
resend the message. 
If 
an “unable to comply” response or no reply is received,
your radio will go to the Unavailable menu.
At the Unavailable menu, you can choose 
SEND or 
EXIT with the Up/Down buttons. If you choose SEND, 
your radio will restart the individual call. If you choose 
EXIT, you will be returned to the individual location 
on the Call Send menu.
