(ii) Please match the settings of control switching switches (SW3, SW4, SW5) to the settings they had before they were
replaced. With these switches, if the printed circuit had a jumper wire before being replaced, set to jumper wire ON if
there was a jumper wire and jumper OFF is these was not.
(iii) Connect the fast-on terminals and connectors that are to the circuit board for the micro-computer.
Connect by matching the wire color of the fast-on terminal with the color printed on the circuit board for the micro-
computer.
Note (1) When connecting to the fast-on connection for the circuit board for the micro-computer, use care so as not to excessively distort the circuit
board.
