circuit board. Loosen and remove the two self-tapping screws that fasten
the ADO to the telephone base and remove the defective ADO. Proceed

inserted in the telephone base.

the base. Position it over the molded locating pins; then lower the board
completely into position in the telephone base. Use the three slotted,
self-tapping screws supplied with the board and install them through the
mounting holes. Tighten the screws.
