Board direction for soldering: '9V+' must be visible! Solder on
seven resistors, paying attention to the resistor values.
The polarity of the resistor is not important!
Solder on two transistors. Pay attention to the direction of the
transistors (1)! Slightly bend the middle transistor leg to the
back (2). Trim excess wires after soldering.
Solder on two sliding switches
in any
direction
Trim excess wires.
Solder on two capacitors. Pay attention to the
polarity - direction shown on the board!
Trim excess wires.

Generally:
Please return the electronics to a certified provider at the end of their useful life. These will then ensure the parts are
disposed of in compliance with directives. This is good for the environment and an important part of actively protecting the environment.
