OPTIONAL SIGNALINGS
Optional Signalings (Programmed by AHT-9-UV software)
This transceiver supports four optional signalings (MSK, DTMF, 2-Tone, 5-Tone).
Click in sequence "program•Optional Features•Optional Signal•Common Set", the
programming software also has three versions: simple version (Supporting MSK Signaling),
DTMF version (Supporting MSK signaling and DTMF signaling) and 5T&2T version
(Supporting MSK signaling and 2T/5T signaling). Please check the version first before
programming. If the version of programming software is different from the radio version,
you cannot program via software.
In transmitting, maybe radio cannot receive the complete signaling, because radio needs
time to switch when in power-saving state. We have to set the "Digit delay", that's, to send
a carrier first, let radio receive signal, then send Signaling to make sure it will be received.
The suggested time for delay time is more than 400S
Press [ ] key, LCD will display "DTMF?", "MSK?" or "2Tone?", Press [ ] and [ ]
keys to make call with the desired call list message. If the corresponding call list has not
been edited, the function is not available.
