Analog sub-audio (CTCSS)/digital sub-audio (CDCSS)
Analog sub-audio (CTCSS)/digital sub-audio (CDCSS) is mainly used to avoid listening to unrelated calls on the
same frequency. If CTCSS/CDCSS is set, within the effective communication range, only calls with the same
subtone signaling set in the channel can be received; but if CTCSS/CDCSS signaling is not set, you can listen to
the effective communication range All calls on the same channel.
Side tone switch
Key side tone: The machine emits key side tone when sending key side tone
ID code side tone: When sending the ID code, the machine will emit the ID code side tone
Button side tone + ID code side tone: When sending button side tone and ID code side tone, the machine emits
the corresponding sound
Note: Button side tone, including number key side tone and TONE tone
