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.
