+Device recovery and bricking
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Its possible to put the device into an unusable state by loading bad images.
+Fortunately, the USRP-N Series can be booted into a safe (read-only) image.
+Once booted into the safe image, the user can once again load images onto the device.
+
+To boot into the safe image, hold down the reset button while power-cycling the device.
+The reset button is a pushbutton switch (S2) located inside the enclosure.
