* Note
R6210 and C6202 replacement note :
Early units use a Main C.B.A. with suffix version number
LSJB2080-1 or LSJB2080-2 which employs two different
methods as shown below.
When replacing R6210 or C6202 on Main C.B.A. with
suffix version number LSJB2080-1 or LSJB2080-2,
order the RESISTOR KIT (LSUC0015), then replace
both R6210 and C6202 at the same time as shown
in Fig.2.
The RESISTOR KIT (LSUC0015) consists of R6210
(ERJ6GEYJ825V), C6202 (ECKR1H102KB5), and
a cushion (VMTS0059).
