Subject:
Change in Rear Cover and Rear Shield Design

Problem
The old rear cover (P/N 51114) has been modified to enhance the fit of the cover, eliminating gaps
between covers. This change required a modification to the rear shield (P/N 51070 ).
The new rear cover (P/N 55995) will not fit properly on an old style instrument, unless the rear shield (P/N
51070) is also changed.
Solution
The new rear cover will fit properly on an old style instrument after changing the rear shield to the new
51070 rev B shield. It is also advisable to order a new connection diagram label (P/N 51674) to place on
the rear shie ld, rather than trying to remove the label from the old shield.
Instruments that have been manufactured with the new rear cover and new shield start with following
serial numbers:
720i-5836
740i-11430
745i-4562
750i-9421
