To reduce the risk of SERIOUS INJURY or DEATH: • Disconnect electric power at the fuse box BEFORE proceeding. • ALL electrical connections MUST be made by a qualified individual. • Upon completion of kit installation, the area MUST be cleared and secured. At that time the unit may be returned to service. Figure 1 Figure 2 Nut Figure 3 Logic Board Screw Plastic Washer Figure 4 Lock Nut Keypad Bracket Figure 5 Lock Nut Standoff Call Button 4
