EPLACING THE CONTROL ELECTRONICS CIRCUIT BOARD
1. Remove the field wire harness from the control electronics circuit
board. Perform step 1 through step 9 in the section Removing the
field wire harness on page 6–5 .
2. Unscrew the three remaining control electronics screws from the
control electronics circuit board. Save the screws.
3. Remove the control electronics circuit board and place it in an
anti-static bag.
4. Position the control electronics circuit board in the inside
escutcheon and secure it using three of the control electronics
screws. Install all but the lower-right control electronics screw.

detection. This setting lets you determine the baud rate for
communication between the lock’s control electronics circuit
board and the panel interface module by setting DIP switches on
the panel interface circuit board.

Switch 8 is set to ON only for locks with a magnetic stripe
insertion card reader; it is set to OFF for locks with a magnetic
