CAUTION: When soldering parts on the circuit board,

20、 do not use too much solder. This could cause a sol der bridge between two foils that should not be connected together. If a solder bridge should occur, reheat the connection and quickly brush away the solder between the foils. Also, after soldering several components, wipe the tip of the sol dering

21、 iron with a cloth or a damp sponge. Keeping the tip clean will insure better solder connections.
