A
Recovery flowchart (1-1)...Changing the VOL OFFSET setting
[From the Main flowchart (1)]
RST MASK 09 (Pink)
Gradually increase the VOL OFFSET value until disappear the
discharge (lit cell).
The VOL OFFSET value must be 101 or less.
B
Current VOL OFFSET > 096?
Display RST MASK 18 (Red 626). / [MKR S18]
Set VOL OFFSET to the current setting value plus 106. / [VOF ∗∗∗]
C
Is there erroneous discharge (abnormal dead cell)?
(Check on the PANEL 1-ADJ menu.)
Display RST MASK 19 (Green 626). / [MKR S19]
D
Is there erroneous discharge (abnormal dead cell)?
(Check on the PANEL 1-ADJ menu.)
Display RST MASK 20 (Blue 626). / [MKR S20]
Is there erroneous discharge (abnormal dead cell)?
(Check on the PANEL 1-ADJ menu.)
E
Set VOL OFFSET to the current setting value minus 56. / [VOF ∗∗∗]
Determine the current VOL OFFSET setting value as the final value.
