After the guests are updated, they often disappear.

According to the query of Baidu Library, the solution to the frequent disappearance of customers after the update is as follows:

1. Please use another function key. There may be other function keys on the interface of the cash register, such as "Cancel" and "Clear". You can try to use these keys instead of the back key to complete the corresponding operation.

2. Use the touch screen. If the cash register is equipped with a touch screen, you can directly click the "Return" icon on the screen with your finger to complete the return operation.

3. Restart the device. First turn off the cash register, then turn it on again to complete the initialization. It is normal to try to use the back key again after restarting.
