Press the PTT switch to initiate the call.
(Proceed to the bulleted list which follows Item 3 in the next section for events that may 
occur next.) 
To make a direct entry from the menu (scroll down to select direct entry), or by using front 
panel controls or the keypad on the Digital Keypad microphone:
Press and hold the Unit Call option key until a tone sounds (approximately one second). 
The last ID called is displayed.
If using the front panel controls, enter the ID of the radio you are calling (eight digits 
for Unit Call) by rotating the select switch, pressing F3 (Standard Control Head) or 
right on the Navigation pad (Lightning Control Head) to advance the cursor. The F2 
button (Standard Control Head) or left on the Navigation Pad (Lightning Control Head) 
can be used to move the cursor back to correct an entered number. With the Digital 
Keypad microphone, enter the number using the DTMF keypad. To cancel the call, 
press the Unit Call Option key again.
Note
If the Unit Call option is programmed to either the F2 or F3 buttons on the Standard 
Control Head, you must use the F6 button to exit the function.
 
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:
- The called party answers the call.
Note
If programmed, the tone sounds until the called party answers or until the timer expires.
- The called party does not answer. Press the Unit Call option switch to end the call.
- If the selected mobile ID is not valid, “INVALID ID” is displayed and an alert tone 
sounds.
- If the radio system is busy, four low tones sound and “BUSY” is displayed. When the 
system is no longer busy, the call back tone (four beeps) is heard and the channel is 
automatically acquired. Press the PTT switch to continue the call.
- If the call is in the secure mode and 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 if it is not answered, end it by pressing the Unit Call option 
switch and placing the microphone on-hook, or by pressing the appropriate exit button.
