Radio Button/LED
* If the signal quality option is on (default is off) and the printer
is awake, the amount of time the blue radio LED is on indicates
the signal strength. For example, if the blue LED is on 90% of
the time, the printer has a very strong signal; however, if the
blue LED is on only 10% of the time, the printer has a very
weak signal. When the signal quality option is turned on, the
blue radio LED indicates signal strength only. When the printer
is asleep, the radio strength is not indicated.
