ALERT TONES
The IPE-200 radios generate a set of unique alert
tones to indicate operating status. The following section
identifies and describes the alert tones used in the
Duplex radio for EDACS applications.
CALL ORIGINATE ALERT
If programmed, a short tone is sounded whenever the
S
key or PTT button is pressed and the radio has
acquired a channel. This tone indicates the user may
begin communications.
CALL QUEUED
If no tone is heard after the transmitter is keyed and
the display flashes, this indicates that the system has
placed the request in a queue. If the
S
key or PTT
button is pressed while in queue, the radio autokeys
(automatically keys) when a channel becomes avail-
able (see AUTOKEY).
AUTOKEY
When the
S
key or PTT button is pressed to place a
call on the system, but is released before the channel
is assigned (e.g. a queued call), the radio automat-
ically keys on the channel when it gets the assign-
ment. The radio generates a long beep and holds the
transmitter keyed for two seconds. Pressing the
S
key or PTT button keeps the channel and sends the
message before this two second time-out has ex-
pired.
