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

For direct entry using front panel controls or the keypad on the Digital Keypad 
microphone:

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

access codes.

2 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 (Standard Control Head) or 

 on the Lightning 

Control head..

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

the Select switch. The 0-9,

, #, 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 eight right-most digits are always 
displayed. With the Digital Keypad Microphone, enter the number using the DTMF 
keypad (a pause indicated by “P” is entered by

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

heard. Briefly press the PTT switch again to send the digits.

5 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.

6 When the telephone call is finished or if it could not be completed for some reason, end 

it by pressing the PHONE option switch again and placing the microphone back on-
hook. This sends the de-access code which tells the system that the call is finished and 
that the repeater can be released.

To answer a telephone call:

1 When a telephone call is received, “ringing” similar to a standard telephone is heard 

and “PHONE” is displayed.

2 To answer the call, press the Phone option switch and press the PTT switch to talk and 

release it to listen.

3 When the call is finished, end it as in the preceding Step 6.
