Slide the lock under the device to the lock position and open the development board.
Select the button with the left and right arrows on the front of the device and press the button. The engine will start when the button is pressed (the display will light up and show the battery level), and the engine will turn off when the button is pressed again. Also, when you change the device from one hand to another, you need to change the buttons on the left and right directions to make sure that the arrow keys are facing the bottom surface when using it. (Red light means it needs to be charged)
Place a small part of the hair on the center guide plate at the top of the hair plate. This product is specially designed to trim hair strands that can only get into the blade.
Treat each section of hair 3 times to ensure an even trim around the hair when you're done. After finishing each small piece of hair, fasten it to the separate side of the untreated hair. Select another small part of the hair and repeat the treatment until the work surface is complete.
