Please check all parts to ensure they are fully equipped. Connect the USB cable to a charger or computer when using for the first time. A red light on the base will illuminate when connected to power and remain on during charging, which takes approximately 3 hours to fully charge. To use the clamp, detach it from the base and attach the table clamp to a suitable position where the plywood thickness is less than or equal to 40mm. Adjust the lamp body to the desired angle. The base features a touch-sensitive switch with a PWM dimmer. A tap of less than 550ms turns the light on or off. Touching and holding for more than 550ms activates the dimming function. Continuous touching gradually increases or decreases brightness, which stops changing when released. Holding the touch for over 3 seconds cycles the brightness to maximum or minimum and locks it until released.
