Press the PTT switch to initiate the call. If the entered number is valid, the display
indicates the alias of the ID if it matches an ID in the call list. Otherwise, the ID you
entered continues to be displayed.
Events that may then occur are as follows:
- If the mobile being called is on the air, “WAIT” is displayed and ringing is heard
until the called party answers or for 20 seconds, whichever occurs first. Pressing the
PTT or an option switch stops the ringing but not the call. When the call is answered,
the voice of the called party is heard.
- If the called mobile does not answer within 20 seconds, a continuous tone sounds and
“NO ANSWER” is displayed.
- If the called mobile is not on the air, a continuous tone sounds instead of the ringing
tone and “NO ACK” (Standard Control Head) or “No Acknowledge” (Lightning
Control Head) is displayed.
- If the busy tone sounds and “BUSY” is displayed, the called mobile has answered the
call but the system is busy. When the system is no longer busy, the call back tone
sounds.
- If your radio or the called radio is inhibited or not programmed to make this type of
call or for the requested secure mode, “RSPNS ONLY” (Standard Control Head) or
“Response Only” (Lightning Control Head) is displayed and an alert tone sounds.
- If your radio does not have the proper encryption key, “KEYFAIL” is displayed and
the call must be made in the clear mode by pressing the Clear/Secure option switch
(if encryption is selectable on the channel). Otherwise, the correct key must be
loaded.

When the call is finished or is not answered, end it by pressing the Unit Call option
