1. Entering and exiting the elevator 
When the elevator floor and car doors are opened, passengers should get off first and then get on. Do not push each other. After the floor door is fully opened, before entering the car, make sure that the floor of the elevator car and the floor of the floor are on the same level to avoid tripping. When arriving at the destination floor, when the car stops and the door is fully opened, confirm that the floor of the car and the floor are on the same level, and then exit the car. 
When entering or exiting the elevator car, the following matters should also be noted: It is prohibited to rush into or out of the elevator car when the door is closing; do not hold the door panel with your hand; do not keep your hand placed between the elevator door and the floor door, or between the door and the door frame for a long time, to avoid getting your hand caught; be careful to prevent walking sticks and high-heeled shoes with pointed tips from getting stuck in the grooves of the floor threshold or the gaps between them, to avoid being pinched; when the elevator is overloaded, there will be audible and visual alarms and the elevator cannot close the door or start moving. At this time, the passengers who enter later should actively exit the elevator car, wait for the next elevator, and wait until the elevator door is completely closed and starts moving before pressing the call button. Overloaded elevators will not respond to calls from other floors until some passengers leave the elevator. This is not a malfunction, but a design to ensure the safety of the elevator and improve its operational efficiency. 
2. Open/close the elevator doors 
Most of the elevators used daily are in automatic mode. The elevator floors and car doors will automatically close after the time set by the control system. Alternatively, the closing button “>|<” on the car control panel can be pressed to make the floors and car doors close immediately, achieving early closing. The elevator starts moving after the floors and car doors are closed. When the elevator reaches the destination floor, the floors and car doors will automatically open. 
If you need to delay the closing of elevator floors or car doors, you can hold down the door-opening button "
