Technical Service Bulletin 040402
This service bulletin provides instructions on how to construct your own IOX-DCX Maintenance
Manual. The following pages contain a front cover page, rear cover page, title page, table of
contents, and a binder spine label. A brief introductory chapter explaining the structure and
philosophy of the manual is also included.
When these elements are combined with a 2-1/2" three-ring binder and chapter dividers you
supply, the result is an attractive maintenance manual to complement the instruction manual set
originally provided with your transmitter.
