Recording a Personal Greeting
Your answering system comes with a pre-recorded outgoing message or greeting that plays when you receive a call: “Hello, no one is available to take your call. Please leave a message after the tone.”
You can record your own personal outgoing greeting. Your recorded greeting must be between two seconds and thirty seconds long.

1. Press /mute. The system announces the number of new and old messages, then starts to play themessages unless it has no messages.
2. Press 5 to stop the announcements or message playback. You will hear intermittent beeps indicating that thesystem is in the command waiting mode.
3. Press 8 to start the recording. The system announces, “Record greeting.” Begin recording after the announcement.
4. When you finish recording, press 8 again or press 5. You will hear a confirmation tone, and your recordedgreeting plays back for you.
   

Selecting a Greeting
Once you have recorded a personal greeting, the phone automatically switches to your personal greeting. You can also switch back and forth between the pre-recorded greeting and your own greeting at any time.

2. Press 5 to stop the announcements or message playback. You will hear intermittent beeps indicating that the system is in the command waiting mode.
