Setup
1. Battery Installation
The HW-710 detector is powered by batteries. Locate the battery compartment on the back of the unit. Open the compartment cover and insert the required batteries, ensuring correct polarity (+/-). Close the compartment cover securely. It is recommended to use fresh, high-quality batteries for optimal performance.
2. Initial Power On
Press the Scan Button (usually marked with a power symbol or 'O') to turn on the device. The LCD display will illuminate, and the device will perform a brief self-calibration. Ensure the device is held away from any objects or surfaces during calibration for accurate results.
Operating Instructions
The HW-710 offers multiple scanning modes for different materials. Familiarize yourself with the device's display and buttons:

Scanning Modes:
- Stud Scan Mode: Detects the edges and center of wood and metal studs. Press the Stud mode Button to activate. The display will show indicators for 1/2 inch, 1 inch, and 1 1/2 inch scan depths.
- Metal Scan Mode: Locates various metal objects such as pipes, rebar, and metal studs. Press the Metal mode Button to activate. The display will show metal depth indication and a metal mode indicator.
- AC Scan Mode: Identifies live AC electrical wiring. Press the AC mode Button to activate. An AC warning icon will appear on the display if live wires are detected.
General Scanning Procedure:
- Select Mode: Choose the appropriate scanning mode (Stud, Metal, or AC) by pressing the corresponding button.
- Place and Calibrate: Place the detector flat against the wall surface where you intend to scan. Press and hold the Scan Button. The device will calibrate. Keep it still until calibration is complete.
- Scan: While holding the Scan Button, slowly slide the detector horizontally across the surface. Maintain firm contact with the wall.
- Interpret Readings:
- Signal Bar: As the detector approaches an object, the signal bars on the display will increase.
- Center Indication: When the device is directly over the center of a stud or object, the "CENTER" indicator will appear, often accompanied by an audible beep.
- Arrow Direction: Arrows on the display will guide you towards the object's location.
- AC Warning: The AC warning icon will flash if live AC wires are detected in any mode.
- Marking: Use the mark pointing feature (top of the device) to accurately mark the detected location on the wall.

Safety Precautions:
Always exercise caution when drilling or cutting into walls. The HW-710 is designed to assist in locating hidden objects, but it is not a substitute for professional judgment. Always turn off power to the area you are working on if you suspect live wiring. The device indicates live AC wires in all modes to help prevent serious mishaps.
