DTMF Telephone Interconnect
Dual Tone Multiple Frequency (DTMF)
tones are
encoded by the radio to dial into (
access
) the
landline telephone network and return (
deaccess)
to
conventional radio operation.
Once the telephone network has been accessed,
phone numbers can be dialled either manually or from
memory. The keypad provides support for DTMF digits
0 to 9, and the characters A, B, C, D, ∗ and #.

The radio is capable of storing a maximum of 9 pre-
programmed phone numbers (up to 12 digits each).
