CAUTION: The PC Boards are ESD-sensitive. Wear an ESD-safe wrist strap or touch a
metallic ground regularly while handling the boards or at any time while working inside the
PX3. See Preventing Electrostatic Discharge Damage on page 35 for more information.
Before starting construction, do a complete inventory, comparing the parts in your kit with the parts list
beginning on 36, to familiarize yourself with all of the parts and to ensure the kit is complete, but do not
remove the rubber band around front panel display board until instructed to do so in the assembly
procedure. It holds the LCD in place until the board is installed. If any parts are missing, contact Elecraft for
a replacement (see, Customer Service and Support on page 53). Recommend you also keep the printed circuit
board assemblies in their anti-static packaging until you are instructed to remove them.
