• List only - Telephone numbers can be selected from a preprogrammed list only (direct 

entry as follows is not allowed).

To recall from a list:

option switch (or select the menu parameter). The alias of the last called telephone 
number is displayed.

2 If required, rotate the Select switch to display the desired number. The alias of each 

number is displayed.

3 Press and then release the PTT switch and “DIALING” is displayed. Refer to the 

bulleted list following Step 3 in the next section for events that may then occur.

To make a direct entry using DTMF keypad:

1 Select the menu parameter or press and hold the PHONE option switch until a tone 

sounds (approximately one second). The alias of the last called telephone number is 
displayed if it is in the phone number list. Otherwise, the last ten digits of the last called 
telephone number are displayed. The phone call mode is indicated by 

 in the 

display.

2 If using the front panel controls, enter the telephone number by rotating and pressing 

the Select switch. A single beep sounds when the switch is pressed (if that option is 
selected). The 0-9, the 

*

, #, and P (pause) characters can be entered (# is displayed as a 

“+”). Numbers up to sixteen digits (including pauses) can be entered, and the number 
scrolls to the left in the display so that the ten right-most digits are always displayed. 
With the HHC, enter the number using the DTMF keypad (a pause indicated by “P” is 
entered by 

*

 #).

3 Press and hold the PTT switch and dial the number using the keypad on the HHC. 

“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. 
When the called party answers, press the PTT switch to talk and release it to listen 
(since the radio operates half-duplex, it is not possible to talk and listen at the same 
time).
