The RST button is located immediately above the CFG port, and behind the same hinged cover.

Holding down the RST button for 2 seconds or longer causes Flash memory to be overwritten, resulting
in a default configuration for the island.

If the island is already auto-configured, there is no consequence other than the island stops during the
configuration process. However, island parameters that you previously customized with the Advantys Configuration
Software are overwritten by default parameters during the configuration process.

Do not attempt to restart the island with the RST button. Pushing the RST button reconfigures the island with default settings.
