430-3802 RadioShack TAD-3802 Digital Answering System
Question: What does FL indicate on the display?
Answer: After the TAD is filled on line 1, the unit will display FL for line 1 and FL for line 2. That means all memory is used up. If the user plays the messages back, they can then be deleted. The FL on each display will go away. While playing messages back on line 1, the FL will still be displayed on line 2 until some or all messages have been deleted.
