The Reset Button (diameter 0.9 mm)
The reset button can perform two functions. One is to reset the switch
to factory default settings and the other is to reboot the switch if the
button has been depressed and release immediately.
Resetting to Factory Default Settings
Depress the Reset button for five seconds to load the factory default
settings. Use a pointed object, such as a straightened paper clip or
needle (the diameter must not exceed 0.9 mm), to depress the Reset
button. When you do so, the STATE LED will start to blink about four
times 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.
