Standing Wave Ratio.
Power Amplifier Protect Threshold:
As long as the temperature is higher than the threshold
value, it stops working , the default threshold value is 80
℃
Fan Work Threshold:
As long as the temperature is higher the threshold value, the fan starts
working. The default threshold value is 45
℃
.
Fan Stop Work Threshold
：
As long as the temperature is higher the threshold value, the fan
stops working. The default threshold value is 35
℃
.
Standing Wave Ratio:
It is used to shows if it’s the antenna match with the radio. The default
value is 3.0
Bandwidth:
It’s used to select the channel spacing of the current channel. Options are, 12.5 kHz,
Colour Code:
It is used to select the colour code of the current channel. As long as the radios
with same colour code in the same frequency can communicate with each other.
Value Range:
0~15, default value is 1.
Squelch Type:
It is used to select the receive mode of current channel.
Options:
CSQ, CTCSS, CDCSS, -CDCSS.
Default Option: CSQ
Squelch Level:
It is used to set the squelch electrical level.
CTCSS:
If select this option, needs to select a CTCSS value, or the transmitter and receiver
but for FCC only 12.5KHz channel bandwidth is allowed.
