EDACS ALERT TONE SETS

There are two EDACS alert tone sets: single and continuous. The EDACS
MDX radio can be programmed to use either set.

Single Alert Tones

CALL QUEUED
SYSTEM BUSY
CALL DENIED
If programmed, a single alert tone sounds when a
group call is received and a two tone alert (one high
followed by one low tone) is sounded for an indi-
vidual call.
You will hear a continuous low pitched tone when
your radio is set to an Rx (decode) only
group/channel and you press PTT on the micro-
phone. This tone indicates that you are not allowed
to place a call on this setting.
The Carrier Control Timer alert is a low pitched
tone you will hear whenever you have kept the
PTT button continuously pressed for a pre-pro-
grammed length of time. Four warning beeps pre-
ceed the tone and transmitter shutdown. The
transmitter shuts down when the steady low
pitched tone starts, interrupting communications.
To maintain communications, release and re-key
the microphone. This resets the timer and turns the
transmitter back on. The CCT is a built in precau-
tion against extended use of the system.
If one short, high pitched tone sounds after the
transmitter is keyed, it indicates the system has
placed the request in a queue. This tone sounds at
both the transmitting and receiving end that a call
is forthcoming. If the PTT is unkeyed while in the
queue, the radio will automatically key push-to-
talk when a channel becomes available (see
AUTOKEY).
If you key the PTT bar and hear three short, me-
dium pitched tones, it indicates that the receiving
party is already on the system or the system is busy
and its queue is full. You must re-key later to access
the system.
A single low pitch beep will sound when the PTT
switch is keyed and the request is denied by the
