3. Safety Information

• Always exercise caution when drilling or cutting into walls.
• The AC mode detects live unshielded AC wires. Shielded wires or wires in conduit may not be detected.
• Do not rely solely on the detector for safety. Always turn off power to the area before drilling or cutting if live wires are suspected.
• This stud finder is designed for use on dry interior walls only.
• Sensing depth and accuracy can vary due to moisture content of materials, wall texture, and paint. Freshly painted walls may require one week or longer to dry for accurate readings.
• This stud finder is not designed to scan materials such as ceramic floor tile, carpeting and padding, lath and plaster walls, foil-covered insulation board, glass, or any other dense material.

5. Operating Instructions

5.1 Power On and Calibration

1. Press the red 'On/Off' button to power on the device.
2. Place the stud finder flat against the wall surface where you intend to scan. Ensure there is no movement.
3. Press and hold the 'Scan Button' (located below the On/Off button) to initiate calibration. The device will calibrate automatically. Wait for the calibration process to complete before moving the device.

5.2 Selecting Scan Modes

The HW-QB6 features dedicated buttons for mode selection:

• Stud Mode Button: Press this button to cycle through the 1/2", 1", and 1 1/2" stud scan modes. If you are unsure of the wall thickness, it is recommended to start with the 1/2" scan mode. If no detection occurs, proceed to 1" or 1 1/2" scan modes.
• Metal Mode Button: Press this button to activate the metal detection mode.
• AC Mode Button: Press this button to activate the live AC wire detection mode.

5.3 Scanning Procedure

1. After calibration and mode selection, slowly slide the device horizontally across the wall surface.
2. Observe the LCD display for indications of detected objects.
3. When an object is detected, the signal bar will increase, and an arrow direction indicator will guide you towards the center of the object. The 'CENTER' icon will appear when the device is directly over the center of the stud or object.
4. Mark the location on the wall using a pencil. For best accuracy, scan the area from both left and right directions and mark both edges and the center.

6. Understanding the Display

The LCD screen provides critical information during operation:

• Low Battery Icon: Indicates when the battery needs replacement.
• Signal Bar: Shows the strength of the detected signal, increasing as you approach an object.
• 1/2", 1", 1 1/2" Scan Mode Icons: Indicate the currently selected stud scan depth.
• Arrow Direction: Guides you towards the center of the detected object.
• Signal %: Displays the percentage of signal strength.
• Stud Mode Icon: Indicates the device is in stud detection mode.
• AC Mode Icon: Indicates the device is in live AC wire detection mode.
• AC Warning Icon: Flashes when live AC wires are detected in any mode.
• Metal Depth Indication: Provides a visual representation of the depth of detected metal.
• Magnetic & Non-magnetic Icon: Differentiates between magnetic and non-magnetic metal.
• Metal Mode Indication: Indicates the device is in metal detection mode.
• Mark Pointing: A visual cue for marking the detected location.
