2.7.6 TELEPHONE CALLS

General
Telephone calls allow you to place and receive
calls over the public telephone system using your
transceiver. If your transceiver is programmed for tele-
phone calls (Phone option switch programmed), they
are placed and received as follows:
Placing a Telephone Call
Telephone calls can be placed by selecting the
number from a preprogrammed phone number list (list
entry) or by directly entering it using the keypad
(direct entry). Direct entry is available with full
keypad (18-key) models only. Proceed as follows:
List Entry Method
1. With a SMARTNET/SmartZone channel selected,
momentarily press the Phone option switch. The
display indicates the alias of the last called tele-
phone number if it is in your phone number list.
Otherwise, the last eight digits of the last called tele-
phone number are displayed.
2. Enter the index of the desired telephone number if
you know it or scroll through the list using the
and keys until you find the desired number.
Press the CLR key to cancel the call.
3. Press the PTT switch to initiate the call. The display
indicates "WAIT" while the connection to the phone
system is occurring. Once connected, the normal
dial tone is heard and the alias of the number being
called is displayed. The radio then automatically
dials the telephone number and the normal ringing
or busy tone is heard. Proceed to the bulleted list
which follows the next method for conditions that
may then occur.
Direct Entry Method (Full Keypad Models Only)
1. With a SMARTNET/SmartZone channel selected,
press and hold the Phone option switch until a tone
sounds (approximately 1 second). The display indi-
cates the alias of the last called telephone number if
it is in your phone number list. Otherwise, the last
eight digits of the last called telephone number are
displayed.
2. Enter the number using the 0-9,
enter a pause (indicated by "P"), press
#. To erase the last digit, press the
number scrolls to the left in the display so that the
eight right-most digits are always displayed.
Numbers up to 16 digits (including pauses) can be
entered. Press the CLR key to cancel the call.
3. Press the PTT switch or the ENT key to initiate the
call. The display indicates "WAIT" while the
connection to the phone system is occurring. Once
connected, the normal dial tone is heard and the
alias of the number being called is displayed. The
radio then automatically dials the telephone number
and the normal ringing or busy tone is heard. Any of
the following conditions may then occur.
•
After the called party answers, press the PTT
switch to talk and release it to listen. You cannot
talk and listen at the same time because the radio
cannot transmit and receive at the same time. Each
time the PTT switch is released, a tone is heard by
the other party that indicates when a response can
be made. To end the call when the conversation is
complete or at any other time, press the CLR key.
•
If the selected number is not valid, "INVALID" is
momentarily displayed, an error tone sounds, and
the call is not initiated. Select a valid number.
•
If enabled by system operator programming, a
number can be dialed during a call by simply
holding down the PTT switch and dialing the
number.
•
If an out-of-range condition exists or the radio
system is not in service, "NO PHONE" is
displayed and a continuous tone sounds. End the
call by pressing the CLR key.
