MISCELLANEOUS
complete, the transceiver returns to the previous system/group. If a message is still present, it is received.
When a priority system/group is sampled while listening to a message on some other system/group, a series of “ticks” may be heard. These ticks are brief interruptions of the audio signal that occur when sampling takes place.
If the menu mode PRIORITY parameter (see page 32) or the PRI option switch is available, priority sampling can be turned on and off. When it is enabled by the switch, “PRI ON” is flashed, and if it is disabled, “PRI OFF” is flashed. If this menu parameter or switch is not available, priority sampling is either enabled or disabled by program- ming.
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 an LTR call or when transmitting.

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 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
