SCAN ON/OFF (conventional-trunking)
When this function is active, the SC icon on the LCD display will
illuminate.
This function is used in the conventional mode to enable or disable the
scanning of the programmed channels in the selected zone. While
scanning the channels, the LCD display will show the current scanned
channel. When activity appears on a channel, the transceiver will stop
the scan, and remain on the active channel for the duration of the Scan
Resume Timer. When the timer expires, the scanning will resume. If
the PTT Switch is pressed during scanning, the transceiver will transmit
on the last active channel.

：当此功能激活时，
SC
图标会显示在
LCD
上。
在常规模式中，此功能用于使能或禁止在被选择分区内的编程信道
扫描。
LCD
会显示当前被扫描的信道。当一个信道有信号时，对
讲机会停止扫描，并停留在繁忙信道中，直到扫描恢复时间结束。
当定时器超时时，扫描将继续。如果在扫描期间，按下
PTT
，对讲机
将在最后一个繁忙信道上发射。
In trunking operation, this function will allow the transceiver to scan all
programmed groups in the selected zone. Any call that matches one of
the programmed groups in the selected zone will be received. If the
PTT Switch is pressed during scanning, the transceiver will transmit on
the last active group.
在集群操作中，此功能将允许对讲机扫描所有在分区中被编程的小组。
在选择的分区中，任何与被编程小组相匹配的呼叫都将被接收。
如果在扫描期间按下
PTT
，对讲机将在最后一次被激活的小组
进行发射。
ZONE SELECT (conventional-trunking)
This function allows the user to switch the currently selected Zone to a
new Zone. When the key is pressed, the next sequential Zone will be
displayed on the LCD display. If the Zone is programmed for trunking
operation, the TR icon will illuminate. After the new Zone is displayed
for two seconds, the transceiver will then display the conventional
channel alpha tag for conventional operation, or begin scanning channels
in the trunking mode.

As Zones are selected, a beep tone will be generated each time the key
is pressed. However, on Zone 1, a high beep tone is generated
signaling that the transceiver is currently on Zone 1. This is especially
