Solder on LEDs, trim wires. Pay attention to the polarity - polarity
shown on the board! The longer leg on the LED is always
POSITIVE!
Insert the battery cable from the back through the contacts

ATTENTION: the soldered on LEDs must be
flat on the board.
To do so, solder on the 4 marked LEDs
then the others. When soldering,
make sure the legs do not short-circuit!
A short-circuit is caused by e.g. accidentally
soldering together 2 wires with solder.
Perform a visual inspection:
Check all soldering points to determine if the solder has caused short-circuits with
other soldering points. If so, you can correct these short-circuits by removing the
short-circuit with the soldering iron.
