Jitter display
|
While the player is stopped and no disc is inserted, press and hold down the  button on the player and the number button, “5” onthe remote controller unit.
|
Jitter display
Measures and displays jitter. Measurement is repeated every second. Read error counter starts at 0 at the mode setting, and increased by one as data read fails at target block. A small defect isallowed to correct by retry. Any possibility is counted as one increment. Repetitive errors after retry increase by two levels or more.
|
J*1 xxx*2 _yyy*3 _zz*4

Measurement of DVD laser current electricity
Measures DVD laser current electricity and displays the result together with the initialization value stored in EEPROM. After measurement, DVD laser is lit tillthe power is turned off (or goes off when the primary power is turned off).
|
DD*1 _034*2 _032*3
*1 : DVD laser current electricity measurement mode
*2 : Current electricity initializationvalue stored in EEPROM
*3 : Present value of current electricity
Values are shown in the decimal digit. The above example indicates that the current electricity initialization value is 34mA and its present valueis 32mA.
|
Automatically exits the mode after five seconds.
