UPC 2 and 5-character supplemental codes 
The UPC standards include the addition of a 
2 or 5-character supplemental code used 
with magazines and paperback books.  To 
read the supplements, you must first enable 
them using the Wireless Reader Setup 
Menu
.  
 
NOTE: Enabling the supplements disallows 
the reading of UPC codes from right to left to assure that the supplement does 
not get missed. 
 
ISBN Specifications 
ISBN (International Standard Book Numbering) bar codes are essentially 
EAN-13 with a 5-digit supplement, where the first 3 digits are the Bookland 
country codes of 978 for books and 977 for periodicals.  Although the bar code 
contains 18 characters, the ISBN format uses only 9 of them, along with a 
newly calculated Mod-11 check digit.  For example, a bar code containing the 
numbers 978055337062153495 would transmit as 0553370626 in the ISBN 
format.  The Wireless Reader has the option of transmitting in the ISBN 
format.
