Installation
Model 12607-001 5-Party Line Switch Kit for Indoor Stations
1. Remove the knob and the old switch. Use a 1/16 -inch (#21) Allen
wrench to loosen the 2 set screws in the selector knob. One screw
is to the right of the party-line indicator; the other screw is in the
end of the knob. After loosening the screws, lift the knob off, and
set it and the screws aside. Save the knob.
2. Write down where all the wires and jumpers are connected.
3. Remove all the wires and jumpers from the old switch.
Note: Keep the wires as long as possible.
4. J-hook all the connections before soldering on the new switch. This
process will ensure a good mechanical connection. See Figure 1.
