The Reset Button
Depress the Reset button for five continuous seconds to load the factory
default settings. Use a pointed object, such as a straightened paper clip or
toothpick, to depress the Reset button. When you do so, the STATE LED
will start to blink about once per second. Continue to depress the STATE
LED until it begins blinking more rapidly; this indicates that the button has
been depressed for five seconds and you can release the Reset button to
load factory default settings.
NOTE
DO NOT power off the switch when loading default settings
