+Older RFX boards require modifications to use the motherboard oscillator.
+If this is the case, UHD will print a warning about the modification.
+Please follow the modification procedures below:
+
+**Step 1: Disable the daughterboard clocks**
+
+Move R64 to R84, Move R142 to R153
+
+**Step 2: Connect the motherboard blocks**
+
+Move R35 to R36, Move R117 to R115
+These are all 0-ohm, so if you lose one, just short across the appropriate pads

+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.
