Change and correction information in this supplement is itemized by page numbers corresponding to the
original manual pages. The pages in this supplement are organized in numerical order by manual page
number.
HOW TO USE THIS SUPPLEMENT
Insert this title page in front of the title page in your manual.
Perform all changes specified for “All Serials”, and all changes through the Series Prefix of your
instrument or board.
Insert any complete replacement pages provided into your manual in the proper location.
If your manual has been updated according to the last edition of this supplement, you need only per-

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 indi-
cated for serial orefix 2804.

SAFETY CONSIDERATIONS
The 5087A Distribution Amplifier Safety Class I instrument (provided with a protective earth terminal),
designed and tested according to international safety standards. To ensure safe operation and to keep the
instrument in safe condition, the user must follow the information, cautions, and warnings provided below
in the Operating and Service Manual. WARNING
Before switching on this instrument, the protective earth terminal of the instrument must be co~eckd to
the protective conductor of the (mains) power cord. The mains plug shall only be inserted in a socket
outlet provided with a protective earth contact. The protective action must not be negated by the use of an
extension cord (power cable) without a protective conductor (grounding).
Whenever it is likely that the protection has been impaired, the instrument must be made inoperative and be
secured against any unintended operation.
All protective earth terminals, extension cords, autotransformers, and devices connected to this instrument
should be connected to a protective earth grounded socket outlet. Any interruption of the protective earth
grounding will cause a potential shock hazard that could result in personal injury.
For continued protection against fire hazard, replace the line fuse only with a 250V fuse of the same cur-
rent rating and type. Do not use repaired fuses or short circuited fuseholders.
Before switching on this instrument, make sure that it is adapted to the voltage of the ac power source.
Any maintenance or service requiring removal of protective covers should be performed by service-trained
personnel who are aware of the hazard involved (for example, fire and electrical shock).
Capacitors inside the instrument may still be charged even if the instrument has been disconnected from its
source of supply.
