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 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 40mm, then rotate the lamp body to the desired position. 5. The base features a touch-sensitive 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, which stops changing when released. Holding for over 3 seconds adjusts brightness to maximum or minimum and locks the setting. Repeat the process to adjust again.
