ALERT TONES

The MDX Conventional mobile radio generates a set of unique alert tones to indicate operating status. The following section identifies and describes the alert tones used in the MDX radio.

SELF CHECK	One beep is sounded after the radio is turned on to
TEST ALERT	indicate that the radio has passed the self diagnostic
	test. Optional in PC programmer.
CALL DISABLED	You will hear a continuous low pitched tone when
ALERT	your radio is set to a receive (decode) only channel
	and you press PTT on the microphone. This tone
	indicates that you are not allowed to place a call on
	this setting.
CARRIER CONTROL	The Carrier Control Timer alert is a pulsing pitched
TIMER	tone you will hear whenever you have kept the PTT
	button continuously pressed for a preprogrammed
	length of time. The transmitter shuts down when
	the pulsing 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 precaution against extended use of the
	system.
T99 CALL RECEIVED	After decoding a T99 call, the received signalling
	2-tone is sounded to alert you of the incoming call.
