4. Insert the precision screwdriver into the rectangular hole of the connector above

the terminal to which the wire is to be attached to compress the spring of the internal

mechanism of the connector, as shown in Figure 10-a;

5. While the precision screwdriver pressures the spring compression, insert the bare

end of the wire into the desired terminal as shown in Figure 10-b;

6. Remove the precision screwdriver, keeping the wire attached, as shown in Figure

10-c;

7. Check if the wire is securely attached to the connector.

5.5 Turning the device on
