MEL Card for the 394 / 392. Ver 2.01. This is the 50 contact card with the sliding door that covers the contacts. To remove it from the instrument you must push it in and then it will pop out. This MEL Card is no longer available. However you can purchase an adapter from Biolytic Lab Performance that allows you to use a newer 68 pin MEL Card in an instrument that was originally designed to use the 50 contact MEL Card. You will need 1 each PN: 181-104604 and 1 each 483-101693 to convert an ABI 392 / 394 that uses a 50 contact MEL Card to a 68 pin MEL Card.
