Notes
• The display shows the total number of "new" (i.e. unreviewed) messages.
Therefore, the display is reset to "0" when you have played back all new
messages, whether they have been erased or not. Be sure to erase
unnecessary messages before the memory becomes full.
• When the number of new messages exceeds 59, "FL" flashes on the display
window.
• If you try to erase all messages in a mailbox with any new messages
remaining. You hear five short error beeps and you cannot erase the
messages.
Tip
You can also listen to the messages or erase the messages from a touch-tone
phone, see "Operating from an outside phone" on page 44.
