Use like a real lift. The indicator has two colors, white and orange. Working pre-doors Safety braking: 1. Press the yellow button with a square on it. 2. To lock the brakes, click to turn the switch so that the line on the switch is pointing upwards in the 'ON' position. If in 'OFF' position, lift will continue to the selected floor. Buttons do not light up after braking. DO NOT SPAM THE STOP BUTTON AS IT WILL CAUSE THE LIFT TO STOP PERMENANTLY .
