Trunking Supervisory Tones
Busy Tone
This tone is similar to the standard telephone busy tone and
it indicates that the radio system is currently busy. The tone
sounds for as long as the
P-T-T
bar on the microphone is
pressed, and the word
"BUSY"
appears in the upper right
portion of the display while this tone is sounding. If the clear-
to-talk tone is programmed, the busy tone does not sound
except when making a telephone call.
Intercept Tone
This is a siren-like tone (alternating high and low tones)
which indicates the following error conditions:
1)
If this tone sounds after the transmit indicator flashes
several times and
"RANGE"
appears in the display, an
out-of-range condition is indicated. To complete a call, you
may need to get closer to your radio system. Once this tone
sounds, no more access attempts are made until the
P-T-T
bar on the microphone is released and then pressed again.
2)
If this tone sounds after the transmitter has been on for
an extended period and
"TX TIME"
also appears in the
display, the transmitter has been disabled by the time-out-
timer feature.
3)
If
"TX INHIB"
is displayed while this tone is sounding,
the selected system is temporarily being used by priority
groups.
NOTE:
The range and busy tones can be stopped by
pressing the
SYS
,
GRP
,
SCN
, or
PHONE
keys or by
pressing and releasing the
P-T-T
bar.
