__ Locate the 2.2K resistor just to the left of the GPS module and just below the 330 ohm
resistor that you just mounted (it will be marked "222"). Remove ONE 2.2K resistor (marked
"222") from the tape and solder it in place. Inspect the solder joints with a 10x jeweler's
loupe to make sure you don't have any solder briges.

__ Locate the 10K resistor near the top of the board and to the left of the resistors that you
just mounted (it will be marked "103"). Remove ONE 10K resistor (marked "103") from the
tape and solder it in place. Inspect the solder joints with a 10x jeweler's loupe to make sure
you don't have any solder briges.
__ Locate the .1 uF capacitor about ½ inch below the resistor you just soldered, it will be
marked .1 uF. It is just above the long row of pads for the processor, and is just to the left of
the spot for the LED marked "1S". Remove ONE .1 uF capacitor from the tape (it will be
brown), and solder it in place. Inspect the solder joints with a 10x jeweler's loupe to make sure
you don't have any solder briges.
Locate the spot on the board for the SN74HC02 Quad NOR Gate, it's a SOIC-14

package (14 leads, surface mount with "J" leads). Using only a tiny bit of solder, tin the lower
right pad on the PC board.
