5-Tone Signaling 23
Wait a few seconds after the transmit indicator ( )
disappears from the control head display, and then
broadcast your message. Phrase your message in
such a way that it requires no acknowledgement,
since the other users cannot all reply at once.
5-Tone
Emergency
Calling
One of the preset 5-tone calls programmed for your
radio may be an emergency call. If programmed,
emergency mode is activated by pressing the auxil-
iary key ( ), or by operating a hidden switch.
An emergency call is then sent to a predetermined
location, such as your dispatcher.
For a description of emergency mode, see “Emer-
gency Mode” on page 44.
Status
Messages
Depending on how your radio was programmed,
you may be able to attach a pre-defined status mes-
sage to some calls. If the radio receiving your mes-
sage has been programmed with the same status
messages, it will decode and display your message.
The message can be up to eight characters long,
indicating your current activity or location, such as
“EN ROUTE” or “AT LUNCH”. Up to 100 sta-
tus messages may be defined at radio programming
time.
