DEFINED 1, and USER DEFINED 2. The last tow formats are user defined.
1) 5-Tone Decode
The decoding template is 5-tone decoding. If the decoding template matches the encoding
template, decoding succeeds.
When receiving proper 5-tone signaling, squelch will be activated according to the “RX Squelch
Mode” defined by the user. You can receive the call and LED flashes orange.
After the radio decoding succeeds, the radio will work according to the decoding call response set
by the dealer.
2) 5-Tone Encode
Encoding template consists of at least one and at most three encoding sequences and each
decoding sequence can be set with 5-Tone, and DTMF. If it is set with 5-Tone, you need to
