DTMF Keypad Operation
The DTMF keypad may be programmed to allow access

only on channels designated for that function. Pressing

appear for 3 seconds if the selected channel is
programmed for DTMF operation. The first DTMF digit
must be pressed within the 3 second period. After
pressing the first digit, the PTT may be released and
transmit will continue as long as extra digits are pressed
within the programmed “hang time.”
