DUAL TONE MULTI-FREQUENCY (DTMF)

The keys on the microphone keypad function as DTMF keys; the 12 keys found
on a push-button telephone plus 4 additional keys (A, B, C, D). This transceiver
provides 10 dedicated memory channels. You can store a DTMF code with up to
16 digits.
Some repeaters in the U.S.A. and Canada offer a service called Autopatch. You
can access the public telephone network via such a repeater by sending DTMF
tones. For further information, consult your local repeater reference.
