radio paging you is stored as the last ID received.
2 To clear or ignore the page, press any option switch. If the PTT switch is pressed, a
group call is placed on the selected channel.
3 To answer the page as a unit call (see Section 5.14.5), press the Unit Call option switch
or select that menu parameter and the alias of the radio paging you is displayed. Press
the PTT switch and respond. One of the following conditions then occur:

continuous tone sounds and “No Ans” is displayed.
- If the radio being called is not on the air, a continuous tone is heard instead of ringing
and “No Ack” is displayed.
