15. Place the circuit board assembly back in position on top of
the Sonalert, ensuring the sides marked +ve and -ve are
lined up with the corresponding terminals on the Sonalert
and if you have a new style light, it is seated in the lens (see
photo below).
16. Use the two screws to connect the wires from the circuit
board (and light if you have the older style) to the Sonalert.
Make sure the wires are connected to the correct terminals
(+ve and -ve) on the Sonalert.
17. Insert the test button through the opening in the faceplate,
and secure it in place using the nut.
18. Insert the sensitivity switch through the faceplate with the
three connection prongs positioned towards the battery
drawer, slightly towards the centre of the reel. Tighten the
nut. Fasten the sensitivity knob on the front of the switch
using the brass screw.
19. Insert the battery tray through the faceplate and secure
using the screws. Connect the black wire with quickconnect fitting to the negative terminal on the battery
tray. Connect the red wire with quick-connect fitting to the
positive terminal. Replace the battery.
20. To reconnect the tape to the circuit board, press down on
the white terminals and insert the tape leads. Release the
terminals and the leads should be secured. The lead on the
bottom of the tape (numbers facing up, may be black mark
on lead) is inserted into the terminal with a white square
below it on the circuit board. See photo below.

not activate, check the polarity of the battery and that all
the electronics are connected properly.
22. Screw the new faceplate to the reel using the new Phillips
screws.

the red and black wires to the correct terminals labeled on
the back of the battery tray. Red wire from the circuit board
to the positive terminal and black wire from sensitivity switch
to the negative terminal. Use the two screws to secure the
tray to the faceplate. Replace the battery.
13. Connect the Molex connector from the faceplate to the
tape.
14. With the Probe in a glass of tap water, turn the Water Level
Meter to the ‘ON’ position. If the connections are correct
