The system is composed of waiter call server, waiter call button and waiter call controller.

LED Display Server (JX1002) with Controller.
There is clock function. When there is no calling, it will show the time. When the calling comes in, it will immediately show it. There are 4 digits in the screen. You can set calling number as 2 digits. In this case, one screen can display two groups of calling numbers. The system is used with calling button with 2 keys which has cancel button. When waiters see the calling number, he will go to serve that table and press the cancel button on the table at first. Then the calling number will be deleted from the display screen. The next calling button will step forward. And the waiter will see another calling. This server is "call service first, be served first". You might be worried about just displaying two groups of calling numbers is not enough, please take it easy. The server has memory chipset which can store 15 calling numbers in it. In this case, all calling will be served one by one without missing.
