Reset Push Button
A small RESET push button is located on the front panel of the Radiance

SECONDARY LEDs and the AUTO DIP switch setting, this push button allows
you to effectively maintain or troubleshoot a PRIMARY link connection.

the RESET push button with the tip of a pointed object. Pushing and holding the
RESET push button has no effect. It is the act of pressing the push button that
causes a reset.
