• Channel Settings
Band Width: select channel spacing for current channel. Options: 12.5kHz、
25 kHz. Default
value: 12.5 kHz.
Color Code: select color code for current channel. Only radios with same frequency and color code can
communicate with each other. Value range: 0~15. Default value: 1.
Squelch Type: select RX mode for current channel. Options: CSQ, CTCSS, CDCSS, -CDCSS. Default
value: CSQ.
Squelch Level: set the squelch electrical level.
CTCSS Frequency: when the CTCSS squelch mode is selected, you need to select one CTCSS
frequency value, otherwise the call between two parties is not possible. Value range: 0~254.1Hz; step
value is 0.1 Hz; default value: 67 Hz.
CDCSS: if the squelch type is CDCSS or –CDCSS, you have to select one CDCSS value, otherwise the
call between two parties is impossible. Value range: 0~777; step value: 1; default value: 023.
Notice:
(1)The squelch level is only applied to analogue channel.
25kHz not for FCC used.
