IOX® / DCX® Series UHF-TV Transmitter
Maintenance Manual
INTRODUCTION
This manual provides extensive information and procedures on the maintenance of Thomson
IOX and DCX transmitters. It is a compilation of individual service bulletins and troubleshooting
tables released and maintained by Thomson Broadcast and Multimedia. Because this
information is periodically subject to updates and revisions, the modular construction of this
manual allows individual bulletins to be replaced, as needed. A version code and date at the
bottom of each bulletin permits easy verification of its revision status.
Updated bulletins may be obtained by contacting Thomson Customer Service at 1-800-345-
9295 or by visiting our download site at http://csg.us.thales-bm.com.
The manual contains three principal sections:
1.
The IOX and DCX Performance Pyramids
•
The first section contains the main body of service bulletins addressing IOX and DCX
maintenance procedures. All bulletins are each numbered for referencing and
identification. A logical pyramid diagram shows the interrelation of one bulletin to
another.
2.
The IOX/DCX Troubleshooting Table (030328)
•
The IOX/DCX Troubleshooting Table (030328) provides vital information for the rapid
diagnosis of various fault conditions. The table attempts to be encyclopedic in nature,
covering a wide variety of problems seen in the field -- from the widespread and
relatively benign to the extremely rare and serious. All IOX and DCX users are
strongly encouraged to skim the table periodically and be familiar with its contents
before a fault condition occurs. The table is frequently updated with information
supplied by customers, field service engineers, and the Thomson Customer Service
Department.
3.
Other Service Bulletins (section for collecting any other pertinent service bulletins)
•
Thomson frequently issues service bulletins addressing product upgrades or other
technical information of which the customer should be aware. The final section of this
manual provides a location to store those service bulletins that do not belong to the
core of procedural bulletins contained in section 1.
