Autopatch (U.s.a. Version Only) - Kenwood TM-631A Instruction Manual

4-4-4, AUTOPATCH (U.S.A. version only)
Some repeaters offer a service known as autopatch. This
allows you to dial a telephone number from your transceiver
and carry out a telephone conversation, much like a car tel-
ephone, or cellular telephone. This function requires the use
of a DTMF (Dual Tone Multi Frequency) pad. In addition to
the normal 12 keys that are found on your telephone the
MC-44DM microphone also provides 4 additional keys, A,
B, C, and D. These keys are required by some repeater sys-
tems for various control functions. You should check with
the control operator of your repeater to determine if their
use is required. A chart is provided that lists the tones that
are generated when you press each key.
1. To activate the DTMF pad, press and hold the PTT
switch.
2. Now press the keys just as you would dial a telephone.
3. The transceiver will remain keyed for about 2 seconds
after you press each number, so you can release the PTT
switch without unkeying the transceiver.
Note: ——_______ Audio tones (Hz)
