DUAL TONE MULTI-FREQUENCY (DTMF) FUNCTIONS
The following DTMF functions require the MC-53DM or
MC-45DM (option) microphone. The keypad on the
microphone includes the 12 keys found on a push-button
telephone plus an additional 4 keys (A, B, C, D). These
additional keys are required for various control operations
by some repeater systems.
