€ 62. Install S2 the same way. € 63. Install J6, the modular RJ-11 phone jack. Pay close attention to the silkscreen and line up the four conductor wires with their respective holes before snapping the part onto the board. Solder all four wire connections being careful not to short them together (they’re really close to each other). Do not solder the plastic posts. The snap fit design will hold it in place. € Install LED D9. The flat side is oriented as shown in the diagram. Leave it standing about 1/2 of an inch off of the board when soldering. After soldering bend it over to a 90є angle at its midpoint so that it faces the outside of the board.
Observe the following diagrams for proper orientation.

Install LED D4 the same way as D9. CONGRATULATIONS ! Your DCI1 DTMF Controller Interface is now complete! Have a final look over your work, paying particular attention to the orientation of all diodes, capacitors, and ICs. Remember that any problems you find now can save time and effort after the unit has been cased up. DCI1 17
