The Reset Button
Depress the Reset button for 5 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. This will cause the STATE LED
to blink on and off. The factory default settings are loaded once the
STATE LED stops blinking (after about 5 seconds). At this point, you can
release the Reset button.
