IOX-DCX Maintenance Manual 

 

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.
