✅· 【Post-sale reminder】: All users who purchase our "weiddw" brand products will enjoy our 12-month free warranty service.We will provide a solution within 24 hours. · 【High Precision】: The laser level is equipped with 4 horizontal laser surfaces arranged in a 360°×4 configuration. The laser grade is Class II, in compliance with the 60825 testing standard. The accuracy of the vertical and horizontal lines is ±1 mm/7m.In a well-lit indoor environment, it is clearly visible and suitable for professional engineering measurement projects such as interior decoration, tile laying, and ceiling installation. · 【Battery and Charging】: This product has a battery capacity of 3600milliampere-hours for 2 batteries.Each battery can last for about 4-5 hours of continuous discharge. The two batteries can work for 8-10 hours. It is a replaceable design, allowing for continuous operation during use without worrying about power outages. The charger is 5V/1A. When the battery is fully charged, the indicator light on the charger changes from red to green. The charging time is approximately 4-5 hours. · 【Pulse Mode】: The laser level instrument has a pulse function. To switch on the pulse function, simply press the middle button between the V and H buttons. Once in pulse mode, in combination with the outdoor receiver, it can receive signals up to 150 feet away. This allows for precise positioning of the line even in conditions where there is no visible light outdoors. This feature is an expansion function. To provide flexible expansion functions for more usage scenarios, please note: (This model does not include a receiver. In the future, we will successively launch packages with receivers.) · 【Auto leveling mode and manual mode】: After turning on the machine, it automatically enters the auto-leveling state. The range of auto-leveling is an inclination angle of less than 4°. If the inclination angle exceeds this range, the machine will emit an alarm sound, indicating that the current inclination angle has exceeded the automatic adjustment range and requires adjustment before use. If you want to use the manual mode, simply hold down the middle button of V and H for 3 seconds. You will hear a "ding" sound and enter the manual mode. Although the manual mode does not have precision, it allows you to project at any inclination angle, increasing the applicable scenarios. · 【Remote control and tripod】: The laser level comes with a remote control and a tripod. The remote control range is 390 inches, allowing you to directly control the light while working. It is convenient to use. The product is equipped with a DIY tripod with a maximum height of 39 inches after elevation, which is convenient for projecting within a height of 39 inches. Thus, the machine can project at the height you desire. · 【The product package includes】: 1× laser level, 1× tripod, 2× lithium-ion batteries, 1× remote controller, 1× charger, 1× universal connector The product package includes: 1× laser level, 1× tripod, 2× lithium-ion batteries, 1× remote controller, 1× charger, 1× universal connector. The laser level is powered by lithium-ion batteries and is equipped with 2× lithium-ion batteries, which can operate continuously for 8-10 hours. The product accuracy is ±1mm/7m. The laser complies with class Ⅱ 60825 laser testing standards and comes with a 39-inch DIY tripod. It can be controlled by remote control to adjust the light distance of 390 inches. When the tilt angle is less than 4°, it will automatically level up. It can be projected in manual mode at will. One-year free after-sales service and 24-hour problem-solving support.
