Cancel of test mode
The mode is written on EEPROM by pressing the POWER button. If the POWER button is pressed again, the unit
returns to the normal state.
* Before pressing the POWER button, make sure that the AUTO pre-adjustment, AUTO adjustment, and AUTO AFB
adjustment have been completed.
* After the value of EEPROM is changed or the AUTO pre-adjustment, AUTO adjustment, and AUTO AFB adjust-
ment are performed again, write on EEPROM by pressing the POWER button. (When the POWER button is
pressed, data is written on EEPROM.)
* When the value of EEPROM has been changed, write the data on EEPROM once. To preform adjustment using
the data, set the unit to the TEST mode again, perform AUTO pre-adjustment, AUTO adjustment, and AUTO AFB
adjustment, and then write the data again on EEPROM.

Pickup Laser Power Check
The laser power in recording/playback can be checked with a laser power meter. However, only confirmation should be
performed as the measurement might be inconstant. Change the pickup only when it is largely out of spec.
Reference value (at the room temperature 25°C)
At playback (ppw): 0.72±0.1 mW
At recording (rpw): 5.5±0.5 mW
Note: Be careful not to stare at laser emission as your eyesight may be damaged.
