the latest circuit improvements. Therefore, when ordering parts, it is important to
include the following information in your order.

If you order a part that has been replaced with a different or improved part, your
local Tektronix field office or representative will contact you concerning any
change in part number.

Modules can be serviced by selecting one of the following three options. Contact
your local Tektronix service center or representative for repair assistance.

Module Exchange. In some cases you may exchange your module for a reman-
ufactured module. These modules cost significantly less than new modules and
meet the same factory specifications. For more information about the module
exchange program, call 1-800-TEK-WIDE, extension 6630.

Module Repair and Return. You may ship your module to us for repair, after which
we will return it to you.

New Modules. You may purchase replacement modules in the same way as other
replacement parts.
