Operating and Programming Manual xxv
Instruments Covered by This Manual
This instrument has a two-part serial number in the form US00000000 which appears on
the serial number plate attached to the rear of the instrument. The first four numerical
digits constitute the serial number prefix and the last 4 significant digits form the suffix.
The prefix is the same for all identical instruments. It changes only when a change is
made to the instrument. The suffix, however, is assigned sequentially and is different for
each instrument. This manual applies directly to instruments having the same serial prefix
as listed under SERIAL NUMBER on the title page.
An instrument manufactured after the printing of this manual may have a serial number
prefix that is not listed on the title page. These unlisted numbers indicate that the
instrument is different from that documented in this manual. The manual for this newer
instrument is accompanied by a ―Manual Updating Changes‖ supplement. This
supplement contains information that explains how to adapt the manual to the newer
instrument.
In addition to change information, the supplement may contain information that corrects
errors in the manual. The supplement for this manual is identified with the manual print
date and part number, both of which appear on the manual title page. Complimentary
copies of the supplement are available from Symmetricom. For information concerning a
serial number prefix that is not listed on the title page or the Manual Updating Changes
supplement, contact the nearest Symmetricom Customer Service Center.
