Might look at getting a breadboard. They are empty circuit boards designed to let you test circuits and chips without permanent soldering.
I don't see why it would require anything besides a battery to be connected. From the manual: "The
dna 30D is a self-contained power regulator which does not require external components for its user interface."
Also "Stealth mode: While locked, holding the fire and down buttons simultaneously for five seconds will switch to stealth mode. In this mode the display is off. It will still show error and lock messages. To switch back to normal display mode, hold down the fire and down buttons simultaneously for 5 seconds. This setting is stored to internal flash memory, and remains if power is removed."
