• Apply power to the SCADAPack controller.
• Continue holding the LED POWER button for 25 seconds until the STAT LED begins to flash on and off continuously.
• Release the LED POWER button.

Note: If the LED POWER button is released before the STAT LED flashes, the controller will start in either the SERVICE or RUN modes.
