| MH-700D | DTMF Microphone with Backlit Keypad (Black) |
Note: This microphone has a built-in DTMF (Dual Tone Multi-Frequency) generator with backlit keypad very similar to that of a standard touch-tone telephone. It is use for signaling applications where the DTMF keypad is use to control various external devices via radio. Some typical applications would be the remote control of a repeater's parameters or accessing phone patch systems.
