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 256 or greater.
Tentative setting value of VOL YNOFS3 D
+ current setting value of VOL YNOFSA D
< 258?
Display RST MASK 21 (Red 1023+). / [MKR S21]
Set VOL YNOFSA D to the current setting value minus 48. / [VYF ∗∗∗]
