Environmental humidity and crashes required by the working environment of POS cash register

Environmental humidity requirements for the working environment of POS cash register

POS cash register strictly belongs to electronic products, so the product needs to pay attention to the surrounding environment during use. For example, the mildness of the magnetic field will affect the normal working performance of the cash register, so we must ensure that the surrounding magnetic field will not Affect the cash register. However, the environmental humidity that is most easily overlooked by users makes many POS cash registers damaged. Let's talk about the requirements of environmental humidity.

Ambient humidity For POS cash registers, relative humidity is 30%-80%. If the humidity is too high, it will not only affect the performance of the POS cash register, but even the dangerous situation caused by the short circuit caused by the humidity, and severely burn out the various components inside the POS cash register. Therefore, in the case of too humid air (especially in the south) or continuous heavy rain, the boot should be cautious. In addition, do not use the pos machine with your hands wet, or use a cloth dampened with water to wipe the POS cash register (especially where the POS is connected). Conversely, too dry is not good, because it is easy to generate static electricity, which is also harmful to POS cash registers.

Therefore, we can put a humidity tester next to it to ensure the balance of environmental humidity.

How to deal with the POS cash register crash symptoms

The POS cash register uses a computer-like function and an innovative product. The product is also equipped with keyboards, mice, and other accessories. The direct-view keyboard is modified to the corresponding function settings according to the cash register function of the cash register. We know that the computer is working. Long time or too little memory will lead to crashes. Of course, POS cash registers as cash registers and other management functions will also have crash symptoms. What should the operators do?

According to the relevant practice, there are two phenomena of dead pig fat in the POS cash register, namely the phenomenon of false death and the phenomenon of real crash. The fake crash is generally caused by the program not working properly. If the program is opened more, the CPU cannot run in time; The real crash phenomenon belongs to the keyboard and the mouse can not move, which has a certain relationship with the CPU memory size.

If the POS cash register encounters a fake crash phenomenon: we need to press Ctrl+Alt+Del", select the program item labeled "Task Manager" in the pop-up list, and select from the "Application" to end. Run the program, then click "end task" to force it to close and let the system resume normal operation.

If the POS cash register encounters a real crash: the only way we can do this is to hold down the "Ctrl+Alt+Del" key combination and select "Shutdown - Restart". Of course, you can also press and hold the restart button on the host. ,

Another troublesome thing is that the POS cash register can't solve the crash phenomenon of the cash register whether it is restarting or ending the task. We can only choose to shut down and unplug the power to turn it back on, but this will give the POS cash register. Years of use and features have a big impact, so don't open so many programs when you're working on a POS cash register.
