An error has been discovered by early recipients of the FX-4CR which causes spurious emissions. This requires a hardware modification to fix.
Owners who are able to solder small 0603 size surface mount components may wish to modify their own rigs. Contact Adam, K6ARK at email@example.com to request the required parts for modification. Instructions are shown below.
Owners who are not able to modify their own rig may remove and return the motherboard and ship it out for repair. Contact firstname.lastname@example.org for more information.
