INSTRUCTION MANUAL FOR SPECIAL FUNCTIONS Introduction The MDP-V10 is provided with special functions, in addition to its normal functions, for convenience and repair work. In this manual, these functions are classified into three sections-“Debug Mode”, “Service Mode”, and “Expansion Key Mode” and explained.
1. OUTLINE 2. DEBUG MODE 1-1. Debug Mode 2-1. Setting the Debug Mode The “Debug Mode” is a state in which the function (debug func- To set the debug mode from the normal mode (normal state), press tion) which displays microprocessor RAM information on the screen the [10/0] key and then the [STOP] key of the remote control while can be used.

The function mode is the basic operation commands, such as STOP The title is displayed at the left side of the screen at the second line, and PLAY, which are transmitted from the mode controller to the while the data is displayed from the third to the ninth lines.
