Supervisory Tones
The following tones are heard at various times when operating this
transceiver. Some or all of these tones may be disabled by the TONES
menu parameter or programming (see “Tone Select” on page 28).
Busy Tone
This tone is similar to the standard telephone busy tone, and it indi-
cates that the radio system is currently busy. The display also indicates
“BUSY” while this tone is sounding. Repeated access attempts are made
while the PTT switch is pressed with this tone sounding. Therefore, it is
not necessary to release the PTT switch to access the system. This tone
sounds only with LTR-Net and LTR calls.
Intercept Tone
This is a siren-like tone (alternating high and low tones) which
indicates the following no access and error conditions:
• No Access - If this tone sounds shortly after pressing the PTT switch
and “NO ACESS” is displayed, the radio system could not be
accessed, perhaps because of an out-of-range condition (see “Opera-
tion At Extended Range” on page 60). Once this tone sounds, no
more access attempts are made until the PTT switch is released and
then pressed again. This condition is indicated only with LTR-Net
and LTR calls.
• Time-Out Timer - If this tone sounds after the transmitter has been
keyed for an extended period and “TIMEOUT” is displayed, the
transmitter has been disabled by the Time-Out Timer feature (see
page 28).
• Transmit Inhibit - If this tone sounds as soon as the PTT switch is
pressed with an LTR-Net or LTR system selected and “TX INHIB”
