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,
20 kHz, 25 kHz, and for FCC only 12.5KHz channel bandwidth is allowed.
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
