Trunked 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 button is pressed, and
the word "BUSY" appears in the lower 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. If "TX INHIB" is displayed while
this tone is sounding, the selected group is temporarily busy.
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
button 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.
Clear-To-Talk

short tone which indicates when speaking can begin. (Refer
