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

entry as follows is not allowed)

• Unlimited - Telephone numbers can be selected from a list and also dialed directly 

entered using the front panel controls or the keypad on the HHC.

All models have the capability to place telephone calls by recalling the number from a list 
or dialing it using the front panel controls or using the Handheld Control Unit (HHC) 
telephone keypad. More information on how to do this follows.

P25 conventional telephone calls use an access code to access the system when placing a 
telephone call, and a de-access code to terminate the call when it is finished. These codes 
are preprogrammed in pairs by the Access/De-Access Code list, and up to 16 pair can be 
programmed. Each conventional P25 channel can be programmed to automatically select 
one of these code pairs. They must match the system codes, and the default code is *1P# 
(the P represents a pause).

To recall from list:

1 Select the conventional channel that is programmed to select the desired access and de-

access codes.

2 Momentarily press the PHONE option switch (or make the menu selection). The 

display indicates the last number dialed by alternately displaying “LAST NUM” and 
the telephone number. In addition, the phone mode is indicated by the 

 icon.

3 If required, rotate the Select switch to display the desired number. The alias and 

telephone number are alternately displayed.

4 Briefly press the PTT switch to send the access code. A dial tone sound should then be 

heard. Briefly press the PTT switch again to send the digits. Proceed to Step 5 (next):

For direct entry using front panel controls or the keypad on the HHC:

5 Select the conventional channel that is programmed to select the desired access and de-

access codes.

6 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, only the last eight digits are displayed. In addition, the phone 
mode is indicated by the 

 icon.
