Recovery flowchart (2-4)...Changing the VOL YNOFSA D setting
[From the Main flowchart (2)]
RST MASK 14 (Cyan 120)
Gradually decrease the VOL YNOFSA D value until disappear the
discharge (lit cell).
The tentative setting value of VOL YNOFS3 D + current setting
value of VOL YNOFSA D must be 266 or greater.
Tentative setting value of VOL YNOFS3 D
+ current setting value of VOL YNOFSA D
< 268?
Display RST MASK 21 (Red 1023+). / [MKR S21]
Set VOL YNOFSA D to the current setting value minus 57. / [VYF ∗∗∗]
Is there erroneous discharge (abnormal dead cell)?
(Check on the PANEL 1-ADJ menu.)
Display RST MASK 22 (Green 1023+). / [MKR S22]
Is there erroneous discharge (abnormal dead cell)?
(Check on the PANEL 1-ADJ menu.)
Display RST MASK 23 (Blue 1023+). / [MKR S23]
Is there erroneous discharge (abnormal dead cell)?
(Check on the PANEL 1-ADJ menu.)
Set VOL YNOFSA D to the current setting value plus 23. / [VYF ∗∗∗]
Determine the current VOL YNOFSA D setting value as the final value.
