Useful life for a vacuum fluorescent tube is defined as the period over which
the light output decreases to half of its specified initial minimum
brightness. Maximum useful life is achieved by display of random text
messages. Users are encouraged to avoid fixed messages wherever
possible, and to clear or blank the display when not in use. A screen
saver mode is provided.
