14. If you have an older style light (see photo below), thread
the leads of the light assembly through the front of the
faceplate and snap the light in place.

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).
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 quick-
connect 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
top of the tape is inserted into the terminal with a white
square below it on the circuit board. See photos below.
21. With the probe in a glass of tap water, turn the Water Level
Meter to the ‘ON’ position. If the connections are correct
the buzzer and light will activate. If the buzzer or light do
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.

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.
