- Replace the NV RAM on the Controller PCB
Do not remove the NV RAM until after you upload its contents to a SD or IC Card depending upon model.
Always touch a metal surface to discharge static on your hands before you touchthe controller board.
Work carefully when you remove the NV RAM, to prevent damage to othercomponents on the controller board. Do not short-circuit the pins of other chips.
On models with more than one NV RAM, chips must always be removed and replaced as a pair.
Be sure the notch on the chip is aligned with properly with the white stenciling on the PCB, do not use the label on the chip for alignment as label placement may vary.
