VOX
VOX function enables you to use the radio without manual operations.
This function can only be set by the dealer, and you have to be
equipped with the specified earphones.
Before using VOX, you must set VOX gain level. Such setting enables
the radio to identify the voice volume. If the microphone is too
sensitive, the background noise will trigger the radio to transmit. If the
microphone is not sensitive enough, it cannot receive your voice when
you speak. Make sure to adjust VOX gain level to proper sensitivity.

Battery Power Saving
The dealer can set the type of this function by programming.
If the battery power saving function is on, 10 seconds after the radio
hasn't receive any signals or no operation is being acted, the radio
enters battery power saving mode. When a signal is received or any
operation occurs, it exits battery power saving mode automatically.
The types include: 1 1, 1 2, 1 4 and OFF.

consumption.
CTCSS/ DCS
The dealer can set CTCSS/DCS tones on radio channels, which
enable you to ignore (not hear) calls from other irrelevant parties who
are using the same channel.
When you receive a signal that has a tone different from the one set
on your radio, you will not hear the signal. Likewise, signals that you
transmit will only be received by parties whose CTCSS/DCS tones
are the same as yours.
Note: Using a CTCSS/DCS channel doesn't mean your calls are
private. If other parties' CTCSS/DCS tones are identical with yours,
they can hear your calls.
