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
TEST ALERT One beep is sounded after the radio is turned on to
indicate that the radio has passed the self diagnostic
test. Optional in PC programmer.
CALL DISABLED
ALERT You will hear a continuous low pitched tone when
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
TIMER The Carrier Control Timer alert is a pulsing pitched
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, re-
lease 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.
OPERATING THE RADIO
TURNING THE RADIO ON
1. Push the POWER switch. The display shows the channel alpha name
once power up is complete. When powering up, the last selected
Channel should be displayed unless the radio is programmed for a
preprogrammed power up. The radio optionally generates a beep once
the power up sequence is complete.
