Recovery flowchart (1-2)
[From the Recovery flowchart (1-1)]
Display RST MASK 13 (green 1023+3). / [MKS S63] Note: Disregard the discharge that may appear during voltage-change setting.
A
Set VOL OFFSET to the setting value 240. / [VOF 240] Gradually decrease the VOL OFFSET value until disappear the discharge (dead cell). � This setting becomes VOL OFFSET_max1.
VOL OFFSET_max1
Note: Make a note of this VOL OFFSET_max1 value.
B
VOL OFFSET_max1 Yes
085?
No
Replacement of abnormal circuits or re-replacement of the panel required
Display RST MASK 14 (blue 1023+3). / [MKS S64]
Set VOL OFFSET to the setting value 240. / [VOF 240] Gradually decrease the VOL OFFSET value until disappear the discharge (dead cell). � This setting becomes VOL OFFSET_max2.
C
VOL OFFSET_max2
Note: Make a note of this VOL OFFSET_max2 value.
VOL OFFSET_max2 Yes
085?
No
Replacement of abnormal circuits or re-replacement of the panel required VOL OFFSET_max
Choose the lower value between VOL_OFFSET_max1 and VOL_OFFSET_max2, and set it as VOL_OFFSET_max.

D
Recovery flowchart (1-3)
[From the Recovery flowchart (1-2)]
Is the VOL OFFSET_max value minus the VOL OFFSET_min value greater than 85? Yes
No
Replacement of abnormal circuits or re-replacement of the panel required
E
Are the VOL OFFSET_max value 176 or greater and the VOL OFFSET_min value 091 or less? Yes Set VOL OFFSET to the setting value 139. / [VOF 139]
No
VOL OFFSET_max
176?
No
Yes Set VOL OFFSET to the setting value VOL OFFSET_max minus 37. Set VOL OFFSET to the setting value VOL OFFSET_min plus 48.
Determine the current VOL OFFSET setting value as the final value.
