Well Water Level and TDS SensorR1 = 1000 Ohms C1 = .1uFR2 = 2200 Ohms C2 = ~.1uFR3 = 10K OhmsYour Circuit board should look like this once the parts have been soldered in place.2. Handset Preparations1. Remove microphone, microphone socket, curly cord and wires from the G3 Telephone Handset. Retain the receiver(speaker) as it will be used in the set. If you have not already done so, REMOVE THE DIODE FROM THE BACKTERMINALS OF THE RECEIVER (SPEAKER).2. Drill a 5/16" hole in the neck of the handset near the ear piece as shown below.3. Take the Miniature Momentary On Push Button Switch and connect a 3" stranded RED wire to one terminal and a 9"stranded RED wire to the other terminal. Make sure that these connections are properly soldered.4. Place the 3" wire through the Vdd terminal on the circuit board from the top side. Solder the wire in place.5. Connect a 12" BLACK stranded wire to the GROUND terminal of the Well Sensor Circuit Board, soldering it in place.6. Take the Telephone handset and insert the probe wire into the original curly cord hole near the mouth piece. Slide the wirethrough the handset to the Receiver compartment. Run a little extra through so that you will be able to attach it to the circuitboard with ease.7. Strip 1/4" off of the end of each of the probe wires, twist and tin them. Insert them in the above probe connection locations,solder in place, clip off ANY excess wire on the foil side of the circuit board.3. Attach the circuit board to the receiver.1. Insert the two #12 X 1/4" screws through the circuit board from the component side. (They should fit through the holessnugly).2. On the foil side of the circuit board, with the screws protruding, place 2 lock washers on each screw. These lock washerswill ensure a connection to the receiver and offset the circuit board so that the soldered copper foils will not short on theback side or metal portions of the receiver.3. Mount the circuit board on the receiver. . Tighten the screws so that they are just snug and the lock washers have beencompressed. This will ensure a continuous and secure connection.4.
