Safety Instructions (attend as well to the rear side of this
instruction)
• All electrical and electronic components included in this kit
shall be used on low voltage only by using a tested and
approved voltage transducer (transformer). All components
are sensitive to heat. During soldering the heat shall be
applied for a very short period only.
• The soldering iron develops up to 450°C. Please keep
continual attention to this tool. Keep sufficient distance to
combustible material. Use a heat resistant pad for this work.

For the diodes please keep special attention to the correct
polarity (marked line for the cathode).
Before assemble the Display is it required to assemble and
solder correctly the two 10-poles and the 14-poles pin-bars
onto the Light-DEC-Service pc-board. Correct assembly of the
two pin-bars will be if the shorter side with the shorter pins will
