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 27).

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 27).

•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”
