Manual

ENCLOSURE 

To install your transceiver in the VEC-1300KC matching enclosure follow these 
instructions 

(read all instructions before beginning ... take your time)

  1.

  Find the front panel decal and 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 with your finger--if the circles 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 are not centered, adjust the 

decal accordingly, then secure.  

f.)

 Use a penknife, or small Exacto

TM

 knife, to cut 

away the unused edges 

(cut from the adhesive side)

 and cut out the component holes 

(cut from the description side)

.  

g.)

 Repeat this procedure for the front panel. 

  2.

  Next, install the two L-brackets on the chassis using two of the 3/16" screws.  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. 

  3.

  Install the four 1/2" mounting screws next.  Insert the screws, from the bottom, 

through the four holes relatively close to each corner of the chassis. 

  4.

  Place the four 3/16" round spacers on the mounting screws. 

  5.

  Now insert the PC board.  This must be done by:  

a.)

 Remove the nuts and washers 

from R1.  

b.)

 Insert the front of the PC board at an angle so the controls enter their 

respective holes.  

c.)

 Push down on the rear of the board.  Make sure the mounting 

screws align with the mounting holes in the PC board before pushing. 

  6.

  Use the four hex nuts to secure the PC board.  Be certain all appropriate components 

are centered with the enclosure holes before tightening.  Put the washers and nuts--
removed from R1--back on and tighten. 

  7.

  Find the knobs and switch caps.  Align the red switch cap with SW1 and push it on.  

Repeat for SW2 with the black switch cap.  If the caps are difficult to push on, then 
rotate them 90° and try again.  Now put the knobs on R1 and C16.  You may need to 
loosen the set screw.  Align appropriately then tighten the set screws. 

  8.

  Locate the two 1/4” phone jacks, two silver washers, and two large nuts.  Place a 

washer on the speaker jack and insert into the rear mounting hole labeled SPKR.  
Put one of the nuts on the jack and tighten.  Repeat this process for the key jack and 
insert into the mounting hole labeled KEY. 

  9.

  Install the top now.  Use the two remaining 3/16" screws for securing the top to the 

L-brackets.  Make sure the L-brackets are aligned properly. 

10.

  Finally, place the four rubber feet on the bottom of the enclosure at the corners.
