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.
If everything is OK here, then the next place to look for a possible fault is a cold
solder joint. These unpleasant things while tinkering occur when either the solder
point was not heated properly, so that the tin comes properly in contact with the
cables, or when the joint was moved while cooling at the time it was just setting.
Such faults can mostly be detected at the matt-look of the surface of the solder
joint. The only solution here is to solder the joint once again.
90% of the reclaimed kits have soldering faults, cold solder joints, incorrect
soldering tin used, etc. Many a returned “masterpieces” bear witness to
improperly done soldering. Therefore, use only the electronic soldering tin “SN 60
Pb” (60% tin and 40% lead) for soldering. This soldering tin has a colophony
core, which acts as soldering flux, in order to protect the soldering joint from
being oxidised during soldering. Other soldering fluxes like soldering grease,
soldering paste or soldering fluid may not be used in any case, because they
contain acids. They can damage the printed circuit board and the electronic
components; moreover, they also conduct electricity and thereby cause leakage
currents and short-circuits.
If everything is okay till this point and the circuit still does not work, then probably
a component is defective.
If you are an electronics amateur, then it is the best for you to consult a known
person, who is well-versed with electronics and has the necessary measuring
equipment.
If you do not have this option, then return the kit properly packed to our service
department along with an exact description of the fault as well as the related
assembly instructions (only an exact description of the fault will enable a proper
repair!). An exact description of the fault is important, because the fault can also
lie in your mains supply or in your external wiring.

Note
Before going in production, this kit was built and tested several times as
prototype. It was released for serial production only when an optimum quality
was achieved with respect to function and operational safety.
The entire assembly is classified in two construction stages, in order to ensure a
certain functional safety while building the system:
1. Construction stage I: Mounting the components on the board
2. Construction stage II: Functional test
