customers can call 1-800-TEK-WIDE (835-9433) for assistance in contacting
their nearest service center. Not all service centers are equipped to repair or
calibrate all instruments; be ready to give the operator the instrument type and
operating options when calling for assistance.
The module exchange program provides an easily accessible means of returning
an instrument to operational status. The defective module is exchanged for a
calibrated module at a cost less than the new module price. The process begins
by contacting one of the module exchange centers. They can be contacted
through your Tektronix field office or representative. In addition, US customers
can call 1-800-TEK-WIDE (835-9433) for assistance in contacting the Television
Board Exchange Center. The center will provide information on the cost of the
module and returning the failed module.
NOTE
. Circuit boards that are damaged due to mishandling or containing
modifications not originated by Tektronix are not acceptable for the exchange
program.
When calling to arrange for a circuit board exchange it is essential that you have
some information ready to relay to our technician. The instrument type and serial
number, along with installed options are absolutely essential. In addition, the
Assembly number (A#) and the nine-digit circuit board part number
(67#–####–##) will help ensure that you are getting a direct replacement.
Finally, if you know or are able to provide the software version number it will
further ensure that the circuit board you receive will return instrument perfor-
mance to what it was before the failure occurred.
The following paragraphs and Table 7–2 are intended to assist in ordering the
exact circuit board replacement. Note that this information is important whether
you are ordering a circuit board from the Module Exchange Center or as a new
replacement part from Tektronix.
