UPS ES 550 - Equipment has blinking red light, no beeping . No back up. Just changed battery.
I have just changed the battery of my UPS ES 550. The red light is blinking, no other light or color. No sound. Battery back up not working (everything shuts off when power goes out). Any ideas what could be wrong?
