This screen displays current servo adjusted data stored in the
EEPROM. Though adjusted data can be initialized with the
CLEAR “R” key on the remote commander, they cannot be restored
after initialization is executed. So, before clearing, make a note of
the adjusted data before you start initialization. For reference, the
drive has been designed so that the gain center value is 20 and offset
value is 80. Other values will be in a range of 10 to 80. If extreme
value such as 00 or FF is set, adjustment will be faulty. In such a
case, check for disc scratch or broken cable, poor connection of
flexible board, then perform adjustment again.

Press the 4 key of the test mode to display the servo error occurrence
history. Press the
v
“R” and
V
“R” keys to scroll the history data
in the range of the most recent error “1” to the error “10”. You can
also type the desired error number from the ten-key of the keyboard.
The upper two columns show the accumulated turn-on hours of the
optical laser unit. The “minute” and the lower data are truncated.
Clearing the error histories
• Clearing the laser turn-on hours data
Press the DVD Display “R” and CLEAR “R” keys in this
order. Both of the CD laser data and DVD laser data are cleared.
• Clearing the error occurrence history data
Press the DVD Top Menu and CLEAR “R” keys in this order.
• Initializing the setups
Press the DVD Menu “R” and CLEAR “R” keys in this order.
When the message “Set Up Initialized” is displayed, it indicates
that the setups are initialized. The screen returns to the EMG
display screen soon.
