3 Press and release the PTT switch and “Dialing” is displayed. Events that may occur are
as follows:
- If the access is successful, a dial tone sounds and the dialed number is displayed and
sent. Either ringing or a busy signal is then heard as with a standard telephone call.

indicate when they can respond. To dial a number after the connection is made, press
the PTT switch and dial the number using the microphone keypad.
- If the selected telephone number is not valid, “Invalid” is displayed and an alert tone
sounds. Select a valid number.
- If the system is busy, “Busy” is displayed and the busy tone sounds. The call will
automatically proceed when the system becomes available.
- If you are out-of-range or the radio cannot be accessed for some reason, “No Phone”
is displayed and an alert tone sounds.
- If the interconnect call you are making or the selected secure mode is not authorized,
“Reject” is displayed and an alert tone sounds.

call must be made in the clear mode using the Clear/Secure option button or menu
parameter (if encryption is selectable on the channel). Otherwise, load the proper
encryption key.
