Turn on the Scan

There are Carrier and Tme scan mode to set in the software. when the "Scan Add" of the channel is set to "Yes", the channel is scannable. When the standby channel is the 22nd channel, and the "Scan Add" of the 22nd channel is set to "No", the radio will automatically start to scan, and the indicator light will flash green in the scan mode. When there is a signal, the radio will automatically stop on the channel for communication.

b. When the scanned channels are less than 2, the radio cannot scan.

Chinese and English Switch

The programming software can set three states: Chinese, English, and Off. Default: Chinese

Time Out Timer (TOT)

Programming software can limit the transmission time of the channel: 0-300s. Default: 30s

CTCSS/ DCS

Programming sofware can be used to set QT/DQT signaling on the radio channel. When the channel is set with QT/DQT signaling, the squelch can only be turned on when a signal using the same QT or DQT is received. If the same channel uses diferent QTIDQT for calling, the squelch cannot be turned on and the radio only lights up the green of the indicator. The bandwidth defaults to narrowband at the factory.
