POWER & LED LIGHT COLORS
Power:
1. Remove the front cover by twisting counter-clockwise to the unlock position.
2. Insert 2 fresh AA batteries according to the polarity markings. The LED light will flash blue when
batteries are inserted.
3. Replace front cover and turn clockwise to locked position.
LED Colors:
BLUE LED: Normal Transmission. The LED light will occasionally flash blue, indicating it is still
transmitting correctly and that no water has been detected. Press the TX button inside the front cover to
force a transmission at any time.
RED LED: Water detected. The LED light will flash red twice every 5 seconds until dry. When water is no
longer detected, the light will reduce in frequency and revert back to flashing blue to indicate
transmission.
PURPLE LED: Battery is low. When the batteries need to be replaced, the LED light will flash purple 5 times
every 30 seconds. (Purple) will flash once every second for 5 seconds.
POSITIONING
• The sensor will work best when simply placed on a floor. It will begin to detect water at 0.031 inches
(0.787mm).
• If sensor is placed vertically (Ex: hung inside a sump pump) the depth of the water needs to be at
least 0.25 inches (6.35mm) high to trigger the sensor.
IMPORTANT: The metal contacts on the sensor should not be in contact with other metal. This will cause
false WET readings and may damage the sensor.
