The FA-VA5 is almost identical to the FA-VA4 that it replaced. The main difference in construction are the new analyzer's USB jack and the use of a cardboard spacer used when installing/soldering header pins.
The USB jack's small circuit board is insulated from the main board by an almost-transparent mica insulator. The circuit board is then soldered to the main board by flowing solder across 16 pads to their corresponding pads on the main board. Be sure that each pad has a solder bridge to its corresponding pad and that no unintentional bridges exist between adjacent pads.
A small cardboard strip is included in the kit. I threw it out thinking it was part of the packing material. After reading the instructions (and retrieving the cardboard from the wastebasket) I was able to install the headers that connect the main board with the display.
At my own choice, no manual was included with my kit - I opted to forgo the two-week waiting period for them to be printed since a pdf of the manual is available online.
Nothing in the instructions mentions the orientation of the three pushbutton switches in relation to the circuit board. There are 4 pins on each switch and 4 holes for each switch in the board - and the switch's pins will fit into the board in any way they're rotated. Upon closer inspection, I could just barely see how they might be meant to go in this way instead of that way and, taking a leap of faith, flowed the solder.
Either I was right and put them in correctly or it doesn't matter how they're oriented - the analyzer worked on power-up.
Here are a few photos of the kit:
