Save the longer clipped component leads. Several of them

will be needed for grounding wires and a jumper.

Install the following 1/4 watt resistors on the bottom side of the

board. Their locations are in the lower right quadrant of the board
when it is oriented the so outline for J1 is in the upper right corner.

_ R16, 1k (brn-blk-red).

_ R17 ,1k (brn-blk-red).

_ R22, 300 ohms (org-blk-brn).

_ R23, 470 ohms (yel-vio-brn).

Turn the board over (top face up) and orient it so that the KX1

lettering is in the upper left corner and the notch is on the lower edge.

Install the following 1/4 watt resistors about 3/4” (2 cm) to the left

of the notch and about 3/4” (2 cm) up from the lower edge of the
board:

_ R12, 6.8k (blu-gry-red).

_ R13, 22k (red-red-org).

Locate resistor pack RP5, 100 k ohm (104). RP5 is a ten-pin in-

line package whose number on the side ends in “104” (see Figure 4).
If you are in doubt about the value, use your DMM to verify that the
resistance between adjacent pins is 100k ohms. Note the dot at one end
indicating pin 1.

Figure 4. Installing Resistor Packs.

Find the outline for RP5 on the top of the circuit board. With the

board face up so that KX1 is in the upper left corner, the outline for
RP5 is just to the left and above the notch at the center of the lower
edge of the board.
