NOTE: Excessive cutting uid deposits on the NC4 receiver may prevent the set-up tool from switching on.
It may be necessary to clean the top of the NC4 receiver to ensure good electrical contact to the set-up
tool.
Using the set-up tool
The set-up tool numerical display provides a correct reading only when the NCi-6 interface unit is in the
set-up mode – that is, when the NC set-up switch (SW1-2) is set to ‘On’.
1. Check that the NC4 receiver head is clean and free of swarf. Push the set-up tool onto the top of the
receiver head and rotate it so that the display is facing you.
2. On the NCi-6 interface unit, set switch SW1-2 (NC set-up) to ‘On’.
