Nikon D300 Repair Manual page 70

(7）Image shutter adjustment
�ased on the 1�125 sec. data of LV�, fine�tune the 1�8��� sec. data of LV15. After the adjustment, inspect
the data deviation at nine points of the shot image.
（8）Pi�el defect compensation � black point
When pi�els of which the output level is under specified value with LV13 equiv. are detected, the
coordinates of the detected pi�els are additionally written as pi�el defect compensation data.
（9）Pi�el defect compensation � white point
Shots are taken on the blackout surface (against dark background). �n case the pi�el output is found to
be beyond the standard value, the detected pi�el coordinates are additionally written as the pi�el defect
compensation data.
（10) T�T adjustment
�lickering, color and luminance of T�T are adjusted.
※ Whenever the DG-PCB or T�T monitor are replaced, be sure to perform "WRITI�G THE T�T �IXED
VALUE."
(11) Obtain reference value
・Sensitivity reference value calculation
The reference body is faced to the color viewer of LV13 equiv. with the ND filter (�� step) being put
between them. Then, the G output average value of (425 pi�els × 425 pi�els), which was deviated to the
right from the center by 425 pi�els, is stored in the D3���SD.DAT file as the sensitivity reference value.
・Sensitivity ratio reference value calculation
The reference body is faced to the shutter tester of LV � equiv. (without filter) and LV13 equiv. (without
filter). Then, the sensitivity ratio reference value GR and G� are calculated and stored in the D3���SD.
DAT file, based on the G�R�� output average of (425 pi�els × 425 pi�els), which is deviated to the right
from the center by 425 pi�els.
※ It is necessary to calculate the reference values of "Sensitivity" and "Sensitivity ratio" in order to prevent
the color temperature fluctuation caused by color viewer�s changes over time from affecting the results of
the shooting image adjustment. By using the reference body, calculate the reference values once in about
every 3 months, when the fluorescent of the color viewer is replaced.
The reference value file "D300BSD.DAT" will be created after getting the reference values.
（12）Initial settings (�actory default settings)
By reset the settings of camera, factory default settings are restored.
Select the language and video mode. Because this setting of RP DG-PCB is blank, be sure to set the initial
default setting when the DG-PCB is replaced.
(13) Confirm adjusting data
Saving�restoring of the system fi�ed values, image register, T��T register, EEPROM1, 2, 3.
The functions of saving/restoring each data is for sending backup data to Service Planning for analysis, if
some problem occurs.
（14）Version �o./ Serial �o.
R�SC firmware version is indicated.
Body serial number is also indicated.
・Whenever the DG-PCB unit or license sheet is replaced, input and change the serial number.
