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. It takes about 3 hours to fully charge. 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 40mm. Rotate the lamp body to the desired position. 5. The base features a touch switch with a PWM dimmer. A tap of less than 550ms controls the on/off function. Touching for more than 550ms activates the dimming function. Continuous touching gradually increases or decreases brightness. Brightness stops changing when released. If touched for more than 3 seconds, the light reaches maximum or minimum brightness and stops changing. Repeat the process to adjust again.
