While the soldering iron is heating, read this first ! 

 
You want to enjoy your Velleman Kit as quick as possible, these 
hints will assist you ! 
First, take your time. Hasty jobs often result in disappointments.  
Make sure your workspace is wide, clean and well lit. Collect all 
the necessary tools you might need for the assembly. Take 
care, while unpacking that nothing is left in the wrapping or 
boxes, such as small parts, manuals and leaflets. Please check 
if all components are present. Use the supplied partlist as a 
guide. In case there is something missing or damaged,  return 
the Kit to your dealer. Read all supplied manuals and notes 
carefully before you start constructing... 
 

The Velleman Kit Warranty 

 
Please read this carefully. In most cases, you can easily solve 
problems yourself. This text tells you all about. 
 
The Kit, you have built or intend to build, was design by a team 
of highly skilled design engineers. Before their design reaches 
the customer, it has been tested and re-tested over and over 
again. This procedure guarantees you that every design actually 
works, when it is put together in the right way. But what if 
something does go wrong ? 
 
Avoid unnecessary expenses and loss of time ! Examine the 
whole circuit closely. An even better procedure is to let 
someone else do this for you. Every tiny detail is important. Are 
all components put in the right place and correctly oriented. 
Watch out for bad or forgotten solder joints and short-circuits !  
What about the power supply ? Is it correct and present ? Does 
the Kit require special calibration or adjustment ? Do the 
possible external devices such as computers, audio sources or 
power circuits match the Kit specifications ?
