Install a .3” jumper wire at location JMP1 on the PC board. Solder.
Install the other .3” jumper wire at location JMP2 on the PC board.
Solder.
Locate the 1-uF electrolytic capacitor.
Important Note: Electrolytic capacitors are polarized devices, and must be
inserted with respect to polarity. The style used in this kit has radial leads; both
leads exit from one end of the device body. The capacitor's plus (+) mounting
hole is noted on the parts placement diagram. If the markings on the capacitor
body are unclear, the plus (+) lead is always the longer of the two.

Observing polarity, install the 1-uF electrolytic at location C1. Solder.
Locate the three .1-uF monolithic capacitors. These capacitors will be installed
at locations C2 through C4 on the PC board.
Important Note: A monolithic cap is similar to a surface-mount "chip" capacitor,
except that it has a lead spot-welded onto each end of the capacitor body.
Monolithic caps have superior radio-frequency operating characteristics, but the
lead welds may fail if the device is over-stressed during installation or removal.
For this reason, never use force to seat a monolithic cap into the PC board. If
the spacing isn't right, pre-form the leads to the correct spacing before
installation!
