| + | [title] Single beep codes |
|---|---|
| + | [* black] There are two types of single beeps - one continuous tone, or a one-second repeating tone. |
| + | [* black] One repeating beep means something has gone wrong in a self-test. Modern firmware groups a number of errors into one code - can be GFI self-test failure (common) or pilot signal self-test failure (far less common), or firmware/EEPROM failure (very uncommon unless you're editing firmware). |
| + | [* black] A constant, nonstop beep means that there is no ground. Ground is detected by passing a small current from an AC line to chassis ground. No ground is most common when using molded extension cords or adapters with a D-shaped ground socket, which has intermittent connectivity. |
