Notes

A. Aluminium screen/polyester tape screen to remain.

B. Heat shrink sleeving fitted to keep the aluminium/polyester tape screen from unwinding from the coaxial signal insulation.

C. The wires must be formed into two bundles with heat-shrink tubing (one containing the four power wires and the other containing the eight signal wires).

D. The heatshrink shown in step 3 must be fitted to prevent the 'overall screen' from shorting to base.

CAUTION:

If any of the wires are incorrectly fitted, the scanner will not function correctly.

Remove the 8-way plug from the signal connector and fit to the cable as shown in the following diagram. The terminal clamps are operated using a screwdriver as shown. Alternatively, you can leave the connector in position whilst connecting the cable, you should then remove the connector and visually check each wire connection.
