OPERATION

Part No. 001-7240-001
1. Access the radio system by briefly pressing the PTT
switch.
2. When a dial tone is heard, dial the desired number
while pressing the PTT switch. If too much time
elapses between digits, the call terminates. Release
the PTT switch and wait for a response.
NOTE: When receiving telephone and other types of
calls, selection of the dial mode is optional because it
does not enhance operation.
2.7.2 SELECTING DIAL MODE
Selecting Dial Mode and Telephone Group - To select
the dial mode and a telephone group in the current
system, press FCN PHONE. If there is more than one
group programmed for telephone calls in the current
system, the first higher numbered telephone group is
selected. If there is no telephone group or a conven-
tional system is selected, “NO PHONE” is displayed
and an error tone sounds.
Selecting Dial Mode Only
- To select the dial mode
without changing the currently selected group, press
FCN DIAL. This method should probably be used
when placing auxiliary calls because the auxiliary call
group must be selected, not a telephone group.
The dial mode is indicated when the handset
portion of the telephone icon is displayed, and a
telephone group is indicated when the base portion
is displayed. Selecting the dial mode using FCN
PHONE displays both icons. When an auxiliary call
group is selected, “
UID” is displayed.
2.7.3 DIALING A NUMBER
Enter the desired number by pressing the 0-9, ,
and keys. Other dialing functions are as follows:
• Only the last eight digits dialed are displayed. To
momentarily display the upper eight digits, press
FCN .
• To erase the last digit, press the CLR key. To erase
the entire number, press FCN CLR.
• To enter a pause, press FCN (each pause equals
one character).
2.7.4 SENDING THE NUMBER
Access the radio system by briefly pressing the
PTT switch. Then when a dial tone is heard, send the
number in the display by pressing FCN SND. The
keypad remains active while in a conversation to allow
additional numbers to be dialed. Simply press the PTT
switch and dial the number. The number in the display
does not change when a number is dialed in this
manner.
The main difference in operation between LTR-
Net/LTR and conventional systems is when the
telephone number is sent (see following).
When an LTR-Net or LTR system is selected, the
PTT switch is briefly pressed to initiate a system
access. Then if the access is successful, the dial tone
sounds and the number can be sent.
When a conventional system is selected, the tele-
phone number can be sent at any time if a carrier is not
being detected on the channel. If a carrier is detected,
the number is sent only if the monitor mode is active.
This ensures that the channel is monitored.
2.7.5 STORING NUMBERS IN MEMORY
Up to ten 16-digit numbers can be stored in
memory and later recalled. Proceed as follows:
1. Enter the number as described in the preceding
“Dialing a Number” section.
2. To store the number, press FCN STR and the
memory location from 0-9.
3. If there is already a number in the selected location,
it is replaced by the new number. To clear a memory
location, simply store a blank display.
4. If an attempt is made to store a number in a locked
position, “NOT AUTH” is displayed.
NOTE: The character is stored and sent normally
(no pause occurs unless it is preceded by FCN), and
the character should not be stored because it may
terminate the call when it is sent.
