NOTE: Priority sampling occurs only on conventional systems and only when scanning is enabled by the SCAN switch. It does not occur when listening to a Multi-Net or LTR call or when transmitting.

Supervisory Tones

The following tones are heard at various times when operating this transceiver. Some or all of these tones can be disabled by the TONES menu parameter or programming. Refer to “Tone Select” on page 32 for more information.

Busy Tone - This tone is similar to the standard telephone busy tone, and it indicates that the radio system is currently busy. It sounds with all Multi-Net and LTR calls, but not conventional calls. Repeated access attempts are made while the PTT switch is pressed with this tone sounding. Therefore, the PTT switch does not need to be released to access the system. The display indicates “BUSY” while this tone is sounding.

Intercept Tone - This is a siren-like tone (alternating high and low tones) which indicates the following out-of-range and error conditions:

•Out-Of-Range - If this tone sounds shortly after pressing the PTT switch and “OUT RNGE” is displayed, the transceiver was unable to contact a repeater. The usual cause for this is an out-of-range condition (see “Operation At Extended Range” on page 61). Once this tone sounds, no more access attempts are made until the PTT switch is released and then pressed again. This condition is not indicated with conventional operation.

•Time-Out Timer - If this tone sounds after the transmitter has been keyed for an extended period and “TIMEOUT” is displayed, the trans- mitter has been disabled by the Time-Out Timer feature (see page 31). This tone sounds with Multi-Net, LTR, and conventional operation. Ten
