How to use the shower head for help? There are pictures.

According to the uploaded photos, turn on the switch of hot and cold water first, and then pull out the button 2 in the picture, and the water will go up, and the water will not flow out from the faucet below. Push it in and water will come out of the tap. Then pull out the 1 button in the figure, and the water will pass through the hose sprinkler. When pushed in, the water will not pass through the hose sprinkler, but directly go to the fixed sprinkler along the stainless steel pipe. I hope it helps you.
