How do I record and play back a message on the voice keypad?

To record, press [#] FUNCTION + [0] VOICE + [1] OFF (the red MESSAGE LED lights). Record your message (up to 2.5 minutes long), then press [1] OFF to end recording. To play back, press [#] FUNCTION + [0] VOICE + [3] STAY. The message remains in memory until a new message is recorded. (Page 7)
