During installation, orient the socket so the notch corresponds to the key on the
PC layout.

When installing sockets, make sure all pins enter the mounting holes and appear
on the opposite side of the PC board (it's easy to fold one or more under the
socket). Also, when soldering, make sure the socket remains flat against the
board surface.
! ! 38. Find a 18 pin IC socket. Orient to U1, install, and solder all pins.
Next, align the BA-1404 IC with the socket, matching its key with the socket
key. When you install, press in slowly--making sure all pins go into the socket
holes and none fold over under the device.
Locate the 9-V battery snap clip, and note the red+ lead and black- lead.
! ! 39. Install the red lead at (+) on the PC board and solder.
! ! 40. Install the black lead at (-) on the PC board and solder.
Locate the two (2) RCA jacks. When installing, make sure all tabs are firmly
seated in place and the jack is level prior to soldering.
! ! 41. Install a RCA jack at J1.

This concludes wiring of your VEC-1292 FM Stereo Transmitter Kit. Before
moving on to the next section, perform a thorough QC (quality control)
inspection. This will uncover any assembly errors that might prevent it from
working properly--or that could damage sensitive parts when you apply power.
Follow this procedure:
1. Compare parts locations with the parts-placement diagram. Was each part
installed where it is supposed to be? Was the correct value used? Start at
one side of the board and work your way across in an organized pattern.
2. Inspect the solder side of the board for cold-solder joints and solder bridges
between tracks or pads. Use a magnifying glass to obtain a clear view of the
