Setting up the moisture alarm
1. Install the CR2032 battery
provided into the battery
compartment on the circuit
board inside the rear part of the
housing.
2. Test the alarm by contacting
the two wires near the bottom
of the housing with a damped
cotton bud; the alarm should
start giving out a repeating
“beep” sound along with a
flashing red light. The “beep”
sound and the light should keep
on going for 5 seconds after the
removal of the damped cotton
bud.
