In addition to the above pieces of hardware, you should still have a thin steel flat
washer, a 3/8" hex nut. These parts were left over from the VEC-821K kit. You
were asked not to discard them, because they will be needed when you installed
the circuit board in an enclosure. If possible, locate them.

STEP-BY-STEP ASSEMBLY

To install your receiver in the VEC-821KC matching enclosure follow these
instructions (read all instructions before beginning ... take your time):

Installing the Circuit Board

Please refer to the Parts Placement diagram for hardware locations.
! ! 1. Find the front panel decal that corresponds with your receiver and the

rear panel decal; separate using scissors. Be sure to leave excess decal
material around the edges. Put the rear panel decal on first. This is
done by: a.) Remove all debris and oil from the chassis. This should
be done using a piece of cloth and alcohol. b.) Remove the crack and
peel to expose the adhesive. c.) Place the decal on the rear panel
without securing it completely. d.) Gently rub the alignment circles
and/or rectangles with your finger--if the circles and/or rectangles are
centered in the enclosure holes (also check the corner alignment
marks) secure the decal by rubbing and removing all air bubbles. e.) If
the alignment circles and/or rectangles are not centered, adjust the
decal accordingly then secure. f.) Use a penknife, or small Exacto
knife, to cut away the unused e dges (cut from the adhesive side) and
cut out the component holes (cut from the description side). g.)
Repeat procedure for the front panel.

! ! 2. Place the bottom chassis in front of you with the round hole in the

front panel facing you.

! ! 3. Install the two L-brackets on the chassis using two of the 4-40 x 3/16"

machine screws (1). The longer side of the L-bracket must be
connected to the chassis using the two holes centered on each edge of
the enclosure. Refer to the diagram on the next page for location and
orientation.

! ! 4. Mount the circuit board in the chassis. Mount the board a follows: a).

Insert the 4-40 x 1/2" machine screws (2) into the holes in the chassis,
then sit the chassis on the table so the screws do not fall out. b). Slip
one #4 x 3/16" spacer (7) over each screw. c). Sit the board down
onto the screws, making sure the knob on the large switch is inserted
into it's hole. e). Secure the boa rd to the screws using four 4-40 hex
nuts, (3) and tighten.

! ! 5. Secure the la rge switch, SW1 using t he 3/8" he x nut (5) and thin steel

washer (4) that came with the VEC-821K kit. Tighten the screws in
place. There will already be a 3/8" hex nut installed on the switch.
This nut needs to remain on the switch as a spacer.

! ! 6. Install the 1/4" mono phone jack (11) as follows: a). Slip the flat steel

washer (15) over the threaded end of the jack. b). Install the threaded
end of the jac k from the inside of the c hassis, through the fro nt panel
hole. c). Position the jack as shown in the Parts Placement diagram.
d). Secure the jack to the fro nt panel using the 9MM hex nut (12).

! ! 7. Install the screw-type terminal board (10) into the horizontal slot on

the rear panel using two 4-40 x 3/16" machine screws (1) and two (2)
4-40 hex nuts (3). Install the terminal board from the inside of the
chassis. The solder lugs should be up and away from U2.

Wiring the Enclosure

You must position the enclosure so the front panel is facing you. For the
following point-to-point wiring steps you will also require the VEC-821K
manual to locate some of the reference points mentioned.

! ! 1 . Connect the insulated wire, located to the point on the circuit board

labeled INPUT, to the right solder lug on the terminal strip. Solder in
place.

! ! 2. Connect the insulated wire, located at GND2 on the circuit board, to

the left solder lug on the terminal strip. Solder in place.

! ! 3. Connect the insulated wire, located at GND3 on the circuit board, to

the short lug on the ¼" phone jack. Solder in place.

! ! 4. Connect the insulated wire, located at SPKR on the circuit board, to

the long lug on the ¼" phone jack. Solder in place.

! ! 5. Locate the piece of double-sided tape. This is to be used for holding

the 9-volt battery clip in place. Locate a place on the underside of the
top cover where the battery will not interfere with any components.
Peel off the backing of the tape and stick it to the chosen location.

! ! 6. The top should now be installed by using the two remaining 3/16"

screws. Make sure the L-brackets are aligned properly and secure the
top to the L-brackets.

! ! 7. Locate the four (4) rubber feet. Remove each of them from the

adhesive strip one at a time and stick one on each corner on the bottom
of the chassis. These are to keep the VEC-821K from sliding around
on the desktop.
