To make direct entry using front controls or the keypad on the HHC:

1 Press and hold the Private Call option key until a tone sounds (approximately one 

second). The last ID called is displayed.

2 If using the front panel controls, enter the ID of the radio you are calling (five digits for 

Private Call or eight digits for Unit Call) by rotating and pressing the Select switch. A 
single beep sounds when the switch is pressed (if that option is selected). With the 
Hand-Held Control Unit (HHC), enter the number using the DTMF keypad. To cancel 
the call, press the Private Call Option key again.

3 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 ANS” is displayed.

- If the called mobile is not on the air, a continuous tone sounds instead of the ringing 

tone and “NO ACK” 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.
