1. Check all the parts to ensure they are fully equipped. 2. Connect the USB cord to a charger or computer when using for the first time. 3. There is a red light on the base, which turns on when connected to a power source. Charging takes approximately 3 hours to reach full capacity. 4. To use the clamp, remove it from the base and attach the table clamp to a suitable position where the plywood thickness is less than or equal to 40 mm. Adjust the lamp body to the desired position. 5. The base features a touch-sensitive switch with a PWM dimmer. A tap of less than 550 ms controls the on/off function. Touching for more than 550 ms activates the dimming function. Continuous touching gradually increases or decreases brightness, which stops changing when released. Holding for over 3 seconds sets the brightness to maximum or minimum.
