lets you start MTRX Studio in various basic modes so it can be restored without having to be returned to the factory.
The Reconfig button is accessed through a hole in the rear panel using a pen or a similar pointed item (such as a paper clip). A green
LED is visible through the hole. When the Reconfig button is activated, the LED lights to indicate the two Recovery modes for
MTRX Studio: last used IP Address and DHCP.

1 Power off MTRX Studio.
2 Press the Reconfig button using a pen or a similar (such as a paper clip) and power the unit on. Hold while the unit is powering
