Caution!
Before you start with the assembly, please read these guidelines completely till the end,
before you start-up the component or the device (please read especially the section on
possible errors and their removal!) and naturally also the safety instructions. You will
then know what is important and to what you need to pay attention, in order to avoid
faults, which can be removed later only with a high effort!

Carry out the soldering and wiring absolutely cleanly and diligently, do not use any
soldering tin containing acid, soldering grease, etc. Make sure that no cold solder joint is
present. An unclean soldering or a poorly done solder joint, a loose contact or a poorly
done assembly imply an extensive and time-consuming search for faults and sometimes
also a destruction of the components, which can often entail a chain reaction and
destroy the complete kit.

Also keep in mind that we will not repair the kits that have been soldered with the help of
acid-containing soldering tin, soldering grease, etc. While assembling electronic circuits
a fundamental knowledge of handling the components, soldering and handling of
electronic or electrical parts is required.

General instructions for making a circuit
The possibility that something does not work after the assembly can be reduced
drastically through an assembly done cleanly and diligently. Check each step, each
solder joint twice, before your proceed! Follow the assembly instructions! Do not carry
out the step described there in a different way and do not skip anything! Put a double
tick-mark on each step: once for assembly and once for checking.

Take your time: Tinkering is not a piece-work, because the time spent here is three-
times less than that spent in looking for faults.

A frequent reason for a non-functioning component is a mounting error, such as
incorrectly inserted components like ICs, diodes and electrolytic capacitors. Please also
pay attention to the colour rings of the resistors, since most of them have colour rings
that can be mixed up easily.

Pay attention to the capacitor values e.g. n 10 = 100 pF (not 10 nF). Checking twice and
thrice can help here. Also see to it that all the IC contacts are actually inserted in the
socket. It can happen very easily that one of these gets bent during insertion. A slight
pressure and the IC must go in the socket all by itself. If this does not happen, then
probably one of the contacts is bent.
