Your Uniden answering machine can record up to 14 minutes of voice messages. The machine announces “No remaining time” and the LED indicator that displays the number of messages reads “FL” when the memory is full, alerting you that you should delete messages. Once the memory is full, callers will not be able to leave you any new messages until you erase some or all of the existing recordings. You can delete a single message from the base or the handset, or delete all of the messages from the base. Warnings Writer Bio
