CAUTION! Failure to complete the following steps might
result in damage to the keypad or circuit

1. Loosen the front cover screw.
2. Hinge the front cover upwards. (See Figure 8). Do not remove the
front cover yet.
3. Disconnect the keypad from the circuit board.
4. Remove the front cover.
CAUTION! Grip all connections to the circuit board by
connecting terminals for assembly and disas-
sembly. Failure to do so could result in dam-
age to the wire leads or connecting terminals.
CAUTION! Do not touch any surfaces of the circuit board. Electrical static discharges may cause
damage to the board. Handle the Smart Controller circuit board by holding only the
edges of the circuit board. Keep replacement boards in their special anti-static bags
until ready for use. Mishandling the circuit board will void the warranty.
