This screen displays current servo adjusted data stored in the
EEPROM. Though adjusted data can be initialized with the
[CLEAR] key on the remote commander, they cannot be restored
after initialization. So, before clearing, make a note of the adjusted
data. 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 cable
disconnection, then perform adjustment again.

Press the [4] key on the remote commander of the emergency history
mode to display the servo error occurrence history. Press the M or m
keys on the remote commander 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-keys on the remote commander.
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] and [CLEAR] keys on the remote
commander 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] keys on the remote
commander in this order.
• Initializing the setups
Press the [DVD MENU] and [CLEAR] keys on the remote
commander 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.
How to Read the Eror Occurrence History Data

design are displayed here. They are not related to the error occ
urrence history.)
3 Order of error occurrence (1 to 9)
