Stanley Fatmax Stud - Finder 400 Manual Free

Introduction

• Place the flat back of the unit flat against the drywall.
• Turn the dial to "Stud Scan."
• Here is the trick: Press and hold the "Spotlight/Sensor" button on the side while pressing the tool firmly against the wall.
• Wait for the beep or the green light. This "zeros out" the wall’s density.

Tips and Precautions

• Slide the stud finder slowly and smoothly along the wall, keeping it flat.
• When it detects a stud, the LCD display will light up, and you might hear a beep (depending on the model).
• Mark the spot where you detect a stud.
