Notes (1) “None” means that jumper wire is not provided on the PCB or the connection is cut
Notes
(2) The replacement PCB is not equipped with jumper wire J1 and J5~J8. Instead, SW6 and 7
are mounted in the same position and have the same functions as jumper wires J1 and J5~J8.
Carry out the local settings in accordance with the table using SW6 and 7.
Note (1) “None” means that jumper wire is not provided on the
