Operation
Viewing the Programmed ID
To review the programmed ID on the channel selected, press the
<#> (pound) key. The ID will de displayed for 5 seconds and then
the display will return to the channel information presentation.
PTT ANI Operation
On specified radio channels, with the press of the PTT button, the
VMDE-200 disables the radio microphone and then transmits the
ANI ID. While the radio is transmitting the data, a tone sounds in the
local speaker to advise the user to hold off talking. After the data is
transmitted, the PTT sidetone stops and the microphone is activated.
The digital burst can be programmed to occur when the PTT is first
pressed, or when the PTT is released, or at both times. If the burst
is programmed for transmission when the PTT is released or the
radio is on a non signaling channel, a short ―go ahead‖ beep will be
heard and there will be no sidetone with data transmission. When
the PTT is released and transmission is over, a courtesy beep is
transmitted to inform the listener that they can now transmit.
The PTT Sidetone and courtesy beep can be individually deactivated
in personality programming.
To reduce the amount of data transmissions, data can be
programmed to not occur during continuing conversations. A value
can be selected for the time since the last PTT press. If the selected
time is not exceeded in subsequent key-ups, data is not sent.
Programmable times are 0, 10s, 20s, 40s, 60s, 120s. [Default = 0].
If the time selected is 0 (zero), ANI will be sent with every PTT press.
Emergency Message
An Emergency message is transmitted whenever the designated
emergency button is held down for greater than the time
programmed in the personality of the radio.
The emergency message ID can be programmed to be different than
the radio PTT ANI. If the ID’s are different and an emergency
message is sent, the VMDE-200 will expect an acknowledgment to
the emergency ID not the PTT ID.
The emergency message transmission will be repeated a
programmed number of times with a programmed period between
transmissions. The repeats will be transmitted regardless of radio
status. Available times are as follows:
Number of repeat emergency transmissions. (1, 5, 10, 15, 20,
forever) [Default = 5]. Time between emergency repeats. (5s, 10,
20, 30s) [Default=10s].
If desired, a warning tone can be sounded in the local speaker to
advise the user that an emergency message has been sent.
In conjunction with a properly configured radio personality, the radio
will change channels prior to sending the emergency message.
The emergency cycle is terminated at the conclusion of the repeats;
