7. Podešavanje
Follow these steps for initial setup of your laser level.
- plasman: Place the laser level on a stable, level surface or mount it using one of the supported methods (see Section 9).
- Uključeno: Slide the On/Off switch to the 'ON' position. The laser lines will activate.
- Samoniveliranje: In self-leveling mode, the device will automatically level itself within its specified range (±4°). If the tilt exceeds this range, an audible alarm will sound, and the laser lines will flash. Adjust the device's position until it levels itself.
- Odabir načina rada: Use the keypad or remote control to select the desired operating mode (see Section 8).
8. Načini rada
The HANMATEK LV12D offers three primary operating modes to suit different application needs.
8.1. Režim samoniveliranja
- This is the default mode when the device is powered on.
- The laser level automatically self-levels within a ±4° range.
- If the device is tilted beyond ±4°, an audible alarm will sound, and the laser lines will flash to indicate it is out of level. Adjust the device until the alarm stops and the lines are stable.

8.2. Manual/Tilt Mode (Oblique Line Mode)
- To activate this mode, press and hold the 'V' button on the keypad or remote control for 4 seconds.
- In this mode, the self-leveling function is deactivated, allowing you to position the laser tool at any desired angle to project inclined lines.
- This is useful for applications such as installing handrails on stairs or decorative sloped patterns.
8.3. Pulse Mode (Outdoor Mode)
- To activate this mode, press and hold the 'H' button on the keypad or remote control for 4 seconds.
- Pulse mode increases the laser line brightness, making it more visible in bright environments or when using a laser detector for longer working distances.
- This mode extends the effective working range of the laser level.
8.4. Remote Operation
- The included remote control allows you to operate the laser level from a distance of 5-7 meters.
- Use the remote to switch between horizontal and vertical lines, adjust brightness, and select operating modes without touching the device.
