A. Optical Status (Tri-colored LED): Green indicates that the unit is receiving the
optimum optical input power. If the optical power falls below the optimum
level, the LED will turn yellow. If the optical power rises above the optimum
level, the LED will turn red.
B. LCD Display: Displays the receiver optical input level, RF attenuator setting, and
equalization setting. The RF levels may be adjusted by the user via the
