All instructions and limitations given in those documents that relate to the resetting of systems both on the ground and in the air must be respected. No reset should be attempted without a thorough appreciation of the technical ramifications. No more than one computer should be reset at any one time. No reset should be attempted in flight unless specifically permitted by the QRH. Maintenance messages remaining after a reset require engineering investigation.
