Vertical line measurement
Aim the laser at the target. Press the MEAS button (7) to measure the lengths of the two lines. The device will calculate the angle between these lines and the vertical line length between their ends.

Countdown
Use the Left/– button (3) or the Right/+ button (9) to adjust the countdown time. Press the MEAS button (7) to measure the length. When the countdown time is over, a measured length value will be displayed on the screen.

Digital level function
Press the DIST button (2). Press the Left/– button (3) or the Right/+ button (9) to scroll to the Digital level mode. The inclination angle value will be displayed on the screen.

Stud detector function

Calibration must be done each time a new mode is selected.
Do not touch the sensing area of the device during measurement in order to avoid mistakes, because the human body has conducting properties.

Metal detection mode

The metal detection mode is used for the detection of hidden objects made of ferrous and non-ferrous metals. Press the SURVEY button (8) to switch to the stud detector function. The metal detection mode is set by default.
Calibration

1. Press the SURVEY button (8) to enter the menu. Select the Metal calibration (Metal detection calibration).
2. Place the device flat against the target surface. Make sure that there are no metal objects around.
3. Press the MEAS button (7) to start the calibration. The calibration will be carried out automatically. When the white part of the display becomes dark, the calibration is completed.
4. Remove the device from the surface and press Power/Back button (4) to exit the calibration mode.

Usage

1. Complete the calibration and place the device flat against the surface to be tested. When a red line appears on the screen, the device is ready to scan.
2. Slowly move the detector across the surface in the direction you want to scan.
3. When the device detects a metal object, the screen will display the icon (non-ferrous metal) or (ferrous metal), the value of the distance to the target, and the signal strength indication. The device will emit a sound. The closer the device is to the object, the stronger the signal will be.
4. When the signal is the strongest, the center mark (18) lights up. Move the device to locate the object according to the signal intensity. !
   If you’re receiving erratic scanning results, it may be a result of humidity, moisture within the wall cavity or drywall, or recently applied paint or wallpaper that isn’t fully dried.

Stud detection mode

The device can scan the surface for wooden and/or metal studs.
Calibration
Automatic calibration

1. Press the SURVEY button (8) to enter the menu. Press the Right/+ button (9) to select the stud detection mode.

Care and maintenance

Do not touch the sensing area of the device during measurement in order to avoid mistakes, because the human body has conducting properties. Do not exclusively rely on the detector to locate items behind scanned surfaces. Do not assume that there is no live cabling inside a wall. Always use caution when nailing, cutting, or drilling in walls, floors, and ceilings that may contain live cabling. Calibrate the device regularly following a routine schedule. This is a class II laser product. Please DO NOT stare into the beam, with unprotected eyes or through an optical device, at any time or direct it towards other people. Do not remove any safety labels. Do not aim the device directly at the sun. Do not try to disassemble the device on your own for any reason. For repairs and cleaning of any kind, please contact your local specialized service center. Protect the device from sudden impact and excessive mechanical force. Do not use the product in explosive environment, close to flammable materials. Store the device in a dry cool place. Only use accessories and spare parts for this device that comply with the technical specifications. Never attempt to operate a damaged device or a device with damaged electrical parts! If a part of the device or battery is swallowed, seek medical attention immediately.

Battery safety instructions

Always purchase the correct size and grade of battery most suitable for the intended use. Always replace the whole set of batteries at one time; taking care not to mix old and new ones, or batteries of different types.
