PLEASE NOTE
This instrument incorporates a new method for tracking changes to its circuit boards.
Starting July 1, 1988, all circuit boards will be labeled with a unique serial number. The
SERIAL number will replace the previously used SERIES number, even though there may
have been no change to the circuit board. Thus, if changes were made after July 1, 1988,
they will be documented in this change sheet using the new circuit board SERIAL number.
Changes made before that time are documented with the SERIES number.
Therefore, Circuit changes described in this change sheet may reference either the older
SERIES number or the new SERIAL number. Using both numbers enables this change
sheet to support both older and newer products. To determine which changes apply to your
instrument, find the instrument's serial number prefix located on the rear panel, and make
the manual changes indicated in this change sheet for that serial number prefix. For
example, if the serial number is 2804A12345, make changes to the manual indicated for
serial prefix 2804.
