Troubleshooting
E
The LED is Blinking
The battery power is low.
• Check the AAA batteries to make sure:
• Each battery is installed correctly, according to (+) and (–)
listed inside the battery compartment.
• The battery contacts are clean and free of rust or
corrosion.
• The batteries are new, high-quality batteries to reduce the
chance of battery leakage.
• Make sure the AAA batteries are in proper working condition.
If in doubt, try installing new batteries.
The LED does not Turn On
There is no battery power.
• Install two new, high-quality, name-brand AAA batteries
in the stud sensor.
• Make sure each battery is installed correctly, according to
(+) and (–) listed inside the battery compartment.
The Stud Sensor is not Finding Studs
• Make sure the batteries are working.
• Make sure you have placed the stud sensor on a wall
made of drywall or another common building material.
The stud sensor will not work on walls made of concrete,
mortar, block, brick work, plaster, carpeting, foil- faced
materials, metallic surfaces, or ceramic tile.
• Make sure you have placed the stud sensor flat against
the wall, the stud sensor is in a vertical position (parallel
to a door or window), and you are pressing and holding
the center button as you move the stud sensor SLOWLY
against the wall.
• Make sure the wall is not too thick. STHT77587 can be
used on walls < .75" (19mm) thick and STHT77588 can
be used on walls < 1.5" (38mm) thick.
• Make sure the wall has a smooth surface.
• Make sure the temperature is within the specified
Operating Range and Relative Humidity.
