6. Screw the nuts on the end of the semi-rigid cables on to the ATT OUT
connector and 1ST CONV IN connector. Finger tighten the nut. If you
encounter any difficulty securing the nut to the connector, loosen the nut from
the connector and try connecting it again. It is critical that the alignment
between the semi-rigid cable and the connector be kept as straight as possible
to avoid possible calibration failure.
7. Tighten the screws securing the preamp assembly to the 1st Converter.
8. Torque the semi-rigid cable nut on the relay for the 1st Converter Out
connection to 10 in-lbs. Do not over-torque the nut. Stop tightening the nut as
soon as the torque wrench first “breaks”.
CAUTION. To avoid damaging the relay connector on the preamp assembly, be
careful not to touch the connector on the relay with the torque wrench while
tightening the nuts.
