2. Press and release the PTT button; the radio performs the necessary
signaling to obtain a communication channel. When the signaling is
complete and the radio is clear to transmit,
TX
indicator turns on and the
channel access tone sounds. Line one shows the accompanying name if
selected from the list of stored numbers or the phone number if entered
directly. The message

displays on line two. The radio then
automatically transmits the programmed number stored in the special call
queue.
3. The telephone ringing will be heard. When someone answers the phone,
press the PTT button and speak into the microphone. Release the PTT
button to listen to the caller. Unsuccessful interconnect signaling returns
the radio to the normal receive mode and the number remains displayed
until the special call is cleared by pressing the
c
button or the time-out
expires or another group or system is selected.
4. To terminate the call, momentarily press the
c
button.
NOTE
The Orion radio is capable of simplex (one-way)
conversation only. The caller can only hear the radio if
the PTT button is pressed (the radio is transmitting)
and the caller can only be heard when PTT is released
(the radio is receiving).
DTMF Overdial/Conventional Mode Telephone Interconnect
Once the radio has established a connection to the public telephone system, it
may be necessary to "over-dial" more digits to access banking services,
answering machines, credit card calls or other types of systems that require
DTMF (Dual-Tone Multi-Frequency) access digits. Overdial operation can
also be used to initiate a telephone interconnect call via DTMF signaling if a
dial tone has already been accessed on the system. This is the method that is
used for making a telephone interconnect call while operating in the
conventional mode but will also function in trunked mode if a dial tone is
directly accessible. Telephone numbers and other number sequences for
overdialing can be stored in the phone list when programming the radio or
stored by the operator in the first ten phone list entries. These numbers are
accessed by pressing
p
then following the selection mode rules.
The following steps are required to dial these numbers:
1. Follow the procedure in
Sending A Telephone Interconnect Call
(Trunked Mode Only
) to establish a connection to the telephone system
or consult the system administrator for the procedure to access a dial tone
on the trunked or conventional system.
