coil and that you grant enough time for drying (best to let it
dry over night). Do not be too thriy or impatient, as that will
not lead to good results!
Run the connection wires of the search coil to the
designated soldering pads on the circuit board. They should
conveniently lead up to the pads, but they must not be ex-
ceedingly long, too. Before you connect the wire ends with
the respective soldering pads, you have to tin-coat them.
This dissolves the insulation of the wire. You can first scrape
bare the wire ends with a blade (e. g. of a screwdriver) and
then tin-coat them by the point of the soldering iron.
Now you solder the connection wires to the designat-
ed soldering pads (Coil). To increase the operational safety,
you can fix the wires with all-purpose glue inside of the box.
Adhesive tape is not suited for this job.
