Power Key
A micro switch is used as a power key on the UI module. The circuitry includes a micro
switch and two diodes, which are needed for the MAD interface. The power key, connected to ROW4, is connected to CCONT and is active in Low state. The power key circuit
is visible in the Display Circuit diagram.
Keyboard
Keyboard backlighting is provided by six LEDs that are compatible with CL191-B1. Backlighting is on when the Light signal is on the High state. The LED color for the keyboard is
blue.
