6.6.2  PLACING A TELEPHONE CALL

1. With a SMARTNET/SmartZone channel selected, 

momentarily press the PHONE option switch. The 
tag (alias) of the last called telephone number is 
displayed.

2. If required, rotate the Select switch to display the 

desired number. The tag of each number is 
displayed. 

3. Press and then release the PTT switch and 

“DIALING” is displayed. One of the following 
conditions then occur:

•

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). 

Each time the PTT switch is released, a go-ahead 
tone is sent to the landside party to indicate when 
they can respond. To dial a number after the 
connection is made, press the PTT switch and dial 
the number using the microphone keypad (if 
available).

•

If the selected telephone number is not valid, 
“INVALID” is displayed and an alert tone sounds. 
Select a valid number.

•

If the system is busy, “BUSY” is displayed and the 
busy tone sounds. The call automatically proceeds 
when the system becomes available.

•

If you are out-of-range or the radio cannot be 
accessed for some reason, “NO PHONE” is 
displayed and an alert tone sounds.

•

If the interconnect call you are making or the 
selected secure mode is not authorized, “REJECT” 
is displayed and an alert tone sounds.

•

If 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 key (if strapped to switchable). 
Otherwise, load the correct key.

4. When the telephone call is finished or it could not be 

completed for some reason, end it by pressing the 
PHONE option switch and placing the microphone 
back on-hook.

6.6.3  RECEIVING 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 (since the radio operates half duplex, it is not 
possible to talk and listen at the same time).

3. When the call is finished, end it by pressing the 

PHONE option switch and placing the microphone 
back on-hook.

The Call Alert™ feature allows pages to be sent 

and received. With SMARTNET/SmartZone opera-
tion, either the Enhanced Private Conversation™ or 
Standard Private Conversation mode may be 
programmed depending on the capabilities of the radio 
system. With P25 Trunked operation, operation is 
similar to the enhanced mode.

Answering a Page

1. When a page is received, five beeps sound and 

“PAGE” is displayed. The ID of the mobile paging 
you is stored as the last ID received.

2. To clear or ignore the page, press any option switch. 

If the PTT switch is pressed, a group call is placed 
on the selected channel.
