WARNING:
Avoid direct exposure of the laser beam to the eyes.
Tips:
1. In really bright rooms or outdoors, the sun can wash out the light, then seeing the laser beam under strong sunlight with naked eye is sometimes difficult. A laser detector will help to get dimmer laser lines outdoors.
2. Don't Shake the device, which might jeopardize the accuracy of the laser level.
3. Store the unit in cool and dry place to avoid any damage caused by heat or moisture.
