Unpacking and Inventory
CAUTION
Do not handle the circuit board assemblies without anti-static protection! Doing so may
damage sensitive components. See Preventing Electrostatic Discharge Damage on page 5 for
important information about handling the boards.
Do a complete inventory before starting construction, comparing the parts in your kit with the parts list in
Appendix A to familiarize yourself with all of the parts and to ensure the kit is complete. When inventorying,
look in the sealed envelopes to identify their contents, but not mix them up. A paper clip or piece of tape will
hold the envelopes closed after you check their contents. Note that a few extras of some screws, nuts and
washers may have been included on purpose.
All dimensions given in the assembly procedure are provided in both US Customary (often called English) and
metric measurements. The native dimensions of the parts are in US Customary units. Approximate metric
equivalents are given to assist those more familiar with the metric system to identify the correct parts.
Screws
A number of different types and sizes of screws and washers are used in the assembly. It is very important that
you use the screw specified in each location or your finished KXPA100 may not fit together properly. In some
places, using the wrong size screw may damage components. The following various screw types and sizes
specified in the text are shown in Figure 1. Images are shown for comparing relative sizes. Due to the printing
process used, they may not be exactly to scale. The lengths of the screws called for in the text are measured as
shown.

Standoffs and Spacers
A number of threaded M-F standoffs and unthreaded spacers are used. Their lengths are measured as shown in
Figure 2.
