Placing an LTR Telephone Call
1. Turn transceiver power on and set the volume as
described in Sections 3.4.1 and 3.4.2.
2. Select the system and group programmed for tele-
phone calls. With high tier models, when a group
programmed for telephone calls is selected, the tele-
phone symbol is displayed.
3. Briefly press the PTT switch to obtain a dial tone. A
successful access and busy or out-of-range condi-
tions are indicated as described in Section 3.4.8. The
following are additional features available when
making telephone calls:
NOTE: The display messages and menu parameters
mentioned in the following information are not avail-
able with low tier models.
Busy - If the system is busy (busy tone sounding)
and the Busy Queuing feature is PC programmed
on the selected system, it is automatically selected
when the PTT switch is released. The display indi-
cates “IN QUEUE” when this mode is selected.
Refer to Section 3.8.7 for more information.
Out-of-Range - If an out-of-range condition exists,
it is indicted by an intercept tone and “OUT-RNGE”
in the display. If the System Search feature has been
enabled by the menu SYS SRCH parameter or pro-
gramming, it is automatically selected when the
PTT switch is released. The display indicates “SYS
SRCH” when this mode is selected. Refer to Section
3.8.8 for more information.
4. When a dial tone is heard, enter the number to be
called in one of the following ways:
• Enter it directly using the 0-9 keys. If too much
time elapses between digits, the call is
terminated.
• If the microphone has a memory, it may be
possible to recall the number from memory and
dial it automatically.
5. After the number is sent, landside ringing should be
heard (a landside busy condition could also be indi-
cated). When the other party answers, press the PTT
switch and respond. The PTT switch must be
pressed to talk and released to listen, the same as
with a standard calls.
6. When the call is finished, press the # key to termi-
nate the call. Three beeps indicate that the call has
been terminated. Terminating the call in this manner
prevents extra billing that may occur for the time
required for the system to automatically detect the
end of the call.
Receiving a Telephone Call
1. Turn transceiver power on and set the volume as
described in Sections 3.4.1 and 3.4.2.
2. Select or scan the system and group programmed for
telephone calls. When a group programmed for tele-
phone calls is selected, the telephone symbol is
displayed (high tier only).
3. When “ringing” is heard, press the PTT switch and
respond. The PTT switch must be pressed to talk and
released to listen as with a dispatch call.
4. When the call is finished, it should be terminated as
in step 6 of the preceding section.
Placing a Landside-To-Mobile Telephone Call
Calls can be placed from a landside telephone to a
mobile transceiver (if the transceiver and radio system
have this capability). With most systems, a mobile
user can be called directly (each has a unique tele-
phone number). With others, the mobile being called
must be specified as follows:
1. Dial the number of the radio system in which the
mobile transceiver is operating.
2. When the system answers, a short tone sounds to
indicate that the number of the mobile being called
should be dialed. This number is five digits long and
must be dialed using a tone-type telephone. The first
two digits are the home repeater number of the
mobile, and the last three digits are a telephone
group ID code of that mobile. With LTR intercon-
nect equipment, the first digit must be dialed within
5 seconds of hearing the tone, and no more than 5
seconds must elapse between digits or the call is
terminated.
