The Three Line Message Director is a state-of-the-art, all LED changeable message sign, capable of displaying messages in either alphanumeric text or arrow board patterns. Absolutely no computer experience needed, this Message Director is by far the easiest CMS to operate in the industry due to the easy to follow step-by-step prompting. This Message Director also has the capability of retaining in memory preprogrammed or user generated messages. An automatic brightness feature gives the sign a more legible viewing distance both day and night while conserving valuable stored energy.
