Charge the product by connecting it to a 5V USB adapter with a Type-C charger cable. Charging status: Battery≤25%: The first battery indicator light flashes 25%<Battery≤50%: The first battery indicator light is long on and the second one flashes 50%<Battery≤75%: The first and second battery indicator lights are long on and the third one flashes 75%<Battery≤100%: The first, second, and third battery indicator lights are long on and the fourth one flashes When the battery level reaches 100%, the indicator remains on for 3 minutes and then goes off. The product can be used normally during charging. Please buy a safe and compliant adapter. 6 Power on/off with the movement locked Power on/off Remark: Power off 1. Under the power-on mode, press and hold the "Switch/mode button" for 1.5 s to power off the product with the movement locked. The battery indicator light is off. 2. When the three laser emitters are turned off via the corresponding laser control buttons, the power indicator light automatically goes off after two hours of no operation. 1. The product cannot automatically calibrate for leveling when working with the movement locked. 2. When working with the movement locked, the currently illuminated laser flashes every 7 s to alert the user to the current non-leveling state. 3. Under the pulse mode, the pulse indicator light is on synchronously, the laser is a little darker than the full bright mode, and the product can be used with a laser receiver (supports 10K frequency). Power on 1. Under the power-off mode, press and hold the "Switch/mode button" for 1.5 s to power on the product with the movement locked. 2. All three lasers are on after the product is powered on, and the lasers can be powered off or back on by using the control buttons corresponding to the lasers. 3. Short press the "Switch/mode button" to switch the laser full bright mode and pulse mode. 7 Power on/off with the movement unlocked Toggle the "Movement locking push button" to unlock the movement Power on Power off Remark: 1. Toggle the "Movement locking push button" to unlock the movement and power on the product with the movement unlocked. 2. All three lasers are on after the product is powered on, and the lasers can be powered off or back on by using the control buttons corresponding to the lasers. 3. Short press the "Switch/mode button" to switch the laser full bright mode and pulse mode. 1. Movement unlock & laser off: Press and hold the "Switch/mode button" for 1.5 s to turn off all the lasers currently working, but the power indicator light remains on as a reminder. 2. Movement lock & laser off: Toggle the "Movement locking push button" to lock the movement and enter the full shutdown state, laser and power indicator lights off. When working with the movement unlocked, if the product tilts over 3°±1°, i.e., beyond the automatic leveling angle, an alarm will be issued. 1. If all three lasers are off, they will flash until the product's automatic leveling angle returns to its normal range. 2. If there is a laser on, the current laser fl…
