code.

Press the Egress Button (the button connecting accross EG IN, (Terminal 9) and (-)GND, 

(Terminal 15) once to enable the keypad for accepting DAP code. The power-up beep stops after 

the Egress Button is pressed.

Key in the DAP code                    and validate it with             (or             ). The Status LED is
