Press one of the buttons for 3 seconds. You will now see a red light. If you press the other button, the same thing happens. The body warmer will then remain in the red position and flash for about 5 minutes.

After 5 minutes the bodywarmer will change to the middle position (colour white). The light will also go out, but the bodywarmer will remain on. You can now set the temperature yourself.

Red: Highest position
Blue: Middle position
White: Lowest position
