Main Frequency and Sub-frequency Switch
Main frequency refers to the current operating and working channel. Sub-frequency refers to the receiving and monitor channel.

2. When menu 14(ECHO) is set as "MANU", when the secondary frequency monitors the signal, it has the same functions as the main
frequency within about 3 seconds, such as: it can carry out transmission scanning priority, etc.
3.Long press the MHZ/SET key to switch main frequency and sub-frequency.
For example, screen public area originally displays TX-L and displays TX-R after switching.
Volume Adjustment
Clockwise rotate the volume knob to increase the output volume and anticlockwise rotate the volume knob to decrease the output volume.
Squelch Adjustment
