You've no doubt clicked here because something's gone wrong. Don’t be too alarmed right off the bat! Our easy guide will help you check a few things before you call us. Following these steps may be able to fix your problem, or at the very least, help us do our job faster.


Does your equipment have a self-diagnostic feature? If you see any lights on the front of the equipment, or through a hole, it does. If there’s a problem, it will likely blink in a pattern, or you’ll see some a group of numbers and letters. As an example, it could be four flashes in a row, or 1 slow flash, then 4 long flashes, or it could say something like “E, 32”. Write down whatever information it’s telling you. With that done, please scroll down to the next step.
