PROGRAM CODES
The microprossesor used in this model is a multi-purpose
type and is used in several different models. To ensure
proper operation and the correct features for your particu-
lar model, the Program Codes must be correct.
Note 1. Option Data 1 (NO. 57 OPT) should be decimal 88
(01011000 binary). See page 3 INITIAL DATA SETUP, step
17, for set up procedure. If this program code is wrong the
TV will not operate properly.
