The Circuit cards are now accessible for changes to the jumper links or repair

work. If the main IDC 20 way ribbon harness is removed for service, use care when

it is replaced. Make sure that all pins on all Circuit cards are correctly inserted into

the IDC sockets; it is easy to bend a pin or mistakenly shift over one pin when

putting a socket on. When re-assembling the Scepter, follow the above steps in
reverse order.
