4. Persekitaran: Ensure the working area is free from obstructions and that the ambient light conditions allow for clear visibility of the laser lines.

5. Arahan Operasi

The BIHUI LLG12 offers multiple operating modes for various applications.

1. Hidupkan/Mati Kuasa:
   • To power on, slide the pendulum lock switch to the unlocked position. The laser level will automatically enter self-leveling mode and project horizontal and vertical lines.
   • To power off, slide the pendulum lock switch back to the locked position. This also secures the pendulum for transport.
2. Mod Meratakan Sendiri:
   • When the pendulum lock is unlocked, the device will self-level within its specified range (typically ±3°). If the device is outside this range, the laser lines will flash rapidly to indicate it cannot self-level. Adjust the position of the device until the lines become stable.
3. Manual Mode (Slope Function):
   • To activate manual mode, power on the device with the pendulum lock in the locked position. The laser lines will be projected but will not self-level, allowing you to project lines at any angle.
   • This mode is useful for tasks like installing handrails or decorative patterns that require non-level lines.
4. Pemilihan Baris:
   • Press the 'H' button to cycle through horizontal line combinations (e.g., one horizontal, two horizontal, all horizontal).
   • Press the 'V' button to cycle through vertical line combinations (e.g., one vertical, two vertical, all vertical).
   • Press both 'H' and 'V' buttons to activate all 12 lines.
5. Pulse Mode (Outdoor Mode):
   • Press the pulse mode button (often indicated by a 'P' or a receiver icon) to activate pulse mode. This mode is used when working with a laser receiver (not included) for extended working ranges or in bright outdoor conditions. The laser lines will appear dimmer to the naked eye in this mode.
