123. Install J8, the other RCA jack.
124. Install J9, the PCB mounted BNC connector.
Take a look over your PC board and check for unsoldered components or
anything that looks less than perfect. You’ll have to be sure everything is right
before moving on to the small front panel board because once we’re finished
with that we'll be firing this kit up. You’ll want to be confident that nothing will
burn up or blow up once power is applied!
F1. On the front panel PC board, install C4, 10nF or 0.01uF ceramic disc
capacitor (marked 103).
F2. Next we’ll install R1, the 10k ohm trim pot (Orange top, marked 103).
It only fits in the board one way, however, we’re going to place it on the
back side of the board, the side you’ve been soldering to so far. This is so
that you can adjust the contrast without pulling the board out of the case.
Simply place it into the holes for it on the backside of the board and be
sure the part is flush to the PC board before soldering all three leads on
the front of the board. It’s a little unconventional but much more user
friendly this way.
F3. Install C6, 0.1uF ceramic disc capacitor (marked 104).
F4. Install R7, 10k ohms (brown-black-orange)
F5. Install R4, also a 10k resistor (brown-black-orange).
F6. Install R3, yet another 10k ohm resistor (brown-black-orange).
F7. Now we’ll install S3, one of the momentary buttons. You’ll see that
the part has a flat side and the silkscreen shows you where to place that
flat side on the board.
F8. In the same way, install S2.
F9. Install the last momentary switch, S4.
F10. Install R6, 270 ohms (red-violet-brown).
F11. Next we’ll install J2 and J5, the two 8-pin dual row connectors. These
will be used to attach the front panel PC board to the main board. They
are placed from the back side of the board similar to how you placed R1.
This is the side you’ve been soldering to that has no silkscreen on it. The
shorter pins go through from the back of the board and are soldered on
the front, leaving the longer pins to be connected to the main PC board in
a later step. Be sure these parts are seated nice and flat before soldering.
F12. The next part we’ll install is the 2x8 line LCD display. First you’ll need
to snap off the two metal tabs on the front of the part to make it ready to
