To stop beeping, press this button once
Uninterruptible power supplies are commonly not designed well enough so that the people who use them can understand how to make them do what they want. As an example, the universal symbols shown on this device probably have much greater meaning for the people who designed the device and probably little or no meaning for the people who use it. Here I have added labeling in an attempt to provide understandable instructions which are clearly visible when the UPS has presented an annoying situation.
