SERVICE MODE A. Market / Region SETUP In the initial condition for this model, Market and Region information are undefined. In the following cases, be sure to set up Market/Region. 1. When updating the system using CD-R (Part code : 0PRADC7114--AJ). 2. -
Page 11: How To Load Software For Mpeg P.w.board
SERVICE MODE D. IMPORTANT NOTE 1. Once the "Market/Region" settings are written into EEPROM (IC801) on the DVD substrate, they cannot be reset. (However, updating the system using CD-R enables you to make new settings.) 2. While the Internal Setup screen is displayed, pushing the Power button enables you to terminate the operations without making any settings. -
