Assembly Instructions; Assembly Instructions - Ramsey Electronics FM10C Manual

Since this is a "professional" transmitter, we sincerely hope you put this to-
gether in a professional manner. This project will not work as well as you
wished if you just slap it together without following good assembly techniques
and follow all instructions. No matter how clear we may think our manual is, if
you have any questions give us a call at the factory. We will be happy to help
you with any problems you may run into.
This is a mixed signal project meaning there is digital, audio, and RF circuitry
all in one unit. As with all RF circuitry, we want to mount the parts AS LOW AS
POSSIBLE to the board. A 1/4" lead length on a resistor not mounted close to
the board can act as an inductor or an antenna causing all sorts of problems in
your circuit. Be aware though that there are stand up components in your cir-
cuit. They don't need to be squished to the board. Keep the portion of the re-
sistor closest to the board mounted right on the board.
For each part, our word "Install" always means these steps:

1. Pick the correct part value to start with.

2. Insert it into the correct PC board location. Make sure the part is mounted flush
to the PC board unless otherwise noted.

3. Orient it correctly. Follow the PC board drawing and the written directions for all
parts - especially when there's a right way and a wrong way to solder it in. (Diode
bands, electrolytic capacitor polarity, transistor shapes, dotted or notched ends of
IC's, and so forth.)

4. Solder all connections unless directed otherwise. Use enough heat and solder
flow for clean, shiny, completed connections.
ASSEMBLING THE FM10C
Sort out all of your parts to begin with, making sure you have all of the parts
required. You can use old egg cartons to hold various parts to make them
easier to find. Make sure to mount parts on the correct side! You will want to
use the parts layout diagram to assist you in finding where the parts go.
Warning: Use only rosin core solder or solder designed to be used with elec-
tronic equipment. Use of acid core solder will void your warranty and produce
a board that will disintegrate in a short period of time.
Note: Save the excess leads cut from installation of resistors and electrolytic
capacitors to use for straps for the crystal and the battery clip.
