Blinking Solutions - Utility
While there are no add-on type of devices that will resolve a "short circuit" on the utility side, manufacturers are adding backup power features to their products to help avoid the annoying inconvenience of appliances losing data.
However, not all electronics and appliances are equipped with this feature, so when purchasing electronics or appliances with a digital display, check to see if the equipment includes a display carry-over feature or a 9-volt battery backup feature.
