(2)Table 8.5 shows the procedure used to change manually from equalized charge to floating charge.

After the charging mode has been changed to equalized charge using the procedure on the previous page, the mode will automatically change back to floating charge after a set period of time has elapsed. Therefore, normally there is no need to change the mode manually as described below.
