Appendix B: Maintenance
This appendix provides information for the basic maintenance of the
power supply. Electronic maintenance on the power supply must be
performed by a trained technician. However, an operator can perform
some basic and routine maintenance.
Cleaning
To clean the power supply, use a soft cloth dampened in a solution of
mild detergent and water. Do not spray cleaner directly onto the
instrument, since it may leak into the cabinet and cause damage.
Do not use chemicals containing benzine, benzene, toluene, xylene,
acetone, or similar solvents.
Do not use abrasive cleaners on any portion of the frequency counter.
Warranty Service
The power supplies are covered by a standard Tektronix one-year
warranty. The warranty statement appears at the front of this manual.
If the power supply fails during the warranty period, return it to
Tektronix for free servicing (subject to conditions of the warranty
statement).
To arrange for warranty service or to get an estimate on a product
that is out of warranty, call your local Tektronix office. If you are
within the continental U.S., you may call 1-800-TEK-WIDE
(1-800-835-9433) for assistance. When you call, have the serial
number of the power supply available. The serial number is located
on the left side of the rear panel.
