The pos machine has brought us a lot of convenience, but have you seen some minor problems in the use of the pos machine? Below I will talk to you about what problems we can't solve during the use of POS machines!
1. Why is the display getting darker and darker?
The display of the VFD customer display screen is based on the inert gas filled in the glass screen, and the inert gas will become more and more ineffective after being used for a long time, so the brightness of the content displayed by the VFD will be darkened, which is a normal phenomenon. However, if it is darkened after a few months of use, this indicates that there is a gas leak in the glass screen, and it is only necessary to return to the factory for replacement.
2. Why is the definition of the machine keyboard lost?
In most cases, it is caused by static electricity. Most of today's programmable keyboards in the world have this problem. Although the keyboard has an electrostatic protection function, if the machine is not grounded, the problem may still occur. Therefore, it is recommended that the user save the keyboard content as a file when defining the keyboard keys, in case the keyboard data is lost next time.
