/CHECKSUM=string

    Specifies a 17-character verification string created by the PAK
    issuer for each PAK. The checksum string is presented in the
    format n-cccc-cccc-cccc-cccc, where n is an integer and c is
    an alphabetic character from A through P. A PAK presents the
    checksum string with hyphen (-)  characters for readability.
    Because LMF does not count hyphens for authorization, you do not
    have to enter them. Otherwise, you must enter the checksum string
    exactly as it appears on your PAK.
