Some repeaters offer a service known as autopatch. This
feature allows you to dial a telephone number from your
transceiver and carry out a telephone conversion,much
like a car telephone, or cellular telephone. This function
requires the use of a DTMF (Dual Tone Multi
Frequency) pad. The MC-45DM optional microphone
provides the normal keys you would have on your
telephone at home, in addition to the normal 12 keys
that are found on your telephone as well as 4 additional
keys, A, B, C and D. These keys are required by some
repeater systems for various control operator of your
repeater to determine if their use is required. A chart is
provided that lists the various tone frequencies that are
generated by the keypad. (Fig.l)
