"Rings to Answer" is on page 12. "Time and Date" begins on page 9.

You may have messages on the voicemail system provided by your telephone company. This system records messages when people call while you're already on the phone. Please contact your telephone company for instructions on accessing their voicemail system.

Greetings:
To retrieve your messages from another phone call your telephone number and when you hear the beep enter your 3-digit security code (if you haven't set it the default code is 1 2 3). The answering machine will beep to confirm the code. You can skip the greeting by entering the security code anytime during the greeting.
To hear your messages locally press and release the PLAY/STOP button. To stop playback, press and release PLAY/STOP again. To restart the message that is playing, press and hold PREVIOUS until the message restarts. To replay the previous message, press and release PREVIOUS. To play the next message, press and release NEXT.
Hope it's all good news - Thank you for using FixYa.com.
