In appropriate measurements by means of the specified test equipment, prop-
er functioning of a unit or module is established.
Components such as connectors and printed circuit boards are examined if
they have changed colour due to temperature effects and thus differ widely
from their normal condition.
Pull off connector.
In case of trouble the unit / module or components such as e.g. connectors,
are to be thoroughly checked for obvious mechanical damage.
This means that components / modules / units are checked for proper func-
tioning while installed.

Ascertain whether all mentioned requirements are met or all measures are tak-

Access is to be gained to the unit / module by observing the given instructions
and safety precautions.
This means that a component / module / unit has to be in a state which does
not give cause to complaints.
In case of trouble the replacement of modules is carried out in order to localize
and eliminate the fault.
Components / modules / units which - due to damage and / or other defects -
no longer meet the respective requirements or components / modules / units
which during troubleshooting were identified as the cause of fault, are to be re-
placed.
This is a visual inspection of the outer appearance and completeness of a
component / module / unit without manual interference by the examiner. This
does not include the necessary preparations and finishing work such as open-
ing and closing of covers or similar.
