Replacement procedure
1) Remove the old connector by cutting the wires at a point close to the connector.
Important:
Do
not re-use a connector (discard it).
2) Strip about 15 mm of the insulation from the ends of the wires. If the wires are stranded, twist
the strands to avoid frayed conductors.
3) Align the lengths of the wires to be connected. Insert the wires fully into the connector.
4) Use the crimping tool to crimp the metal sleeve at the center position. Be sure to crimp fully to
the complete closure of the tool.
L. When connecting or disconnecting the VCR connectors, first, disconnect the ac plug from the ac
supply socket.
