3 Assembly hints 1. Assembly (Skipping this can lead to troubles! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: A good quality soldering iron (2540W) with a small tip. Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called thinning and will protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning. Thin raisincore solder. Do not use any flux or grease. A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they cannot fly towards the eyes. Needle nose pliers, for bending leads, or to hold components in place. Small blade and Phillips screwdrivers. A basic range is fine. For some projects, a basic multimeter is required, or might be handy Assembly Hints : Make sure the skill level matches your experience, to avoid disappointments. Follow the instructions carefully. Read and understand the entire step before you perform each operation. Perform the assembly in the correct order as stated in this manual Position all parts on the PCB (Printed Circuit Board) as shown on the drawings. Values on the circuit diagram are subject to changes. Values in this assembly guide are correct* Use the checkboxes to mark your progress. Please read the included information on safety and customer service * Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as NOTE on a separate leaflet. 3
4 Assembly hints 1.3 Soldering Hints : 1 Mount the component against the PCB surface and carefully solder the leads 2 Make sure the solder joints are coneshaped and shiny 3 Trim excess leads as close as possible to the solder joint REMOVE THEM FROM THE TAPE ONE AT A TIME! AXIAL COMPONENTS ARE TAPED IN THE COR RECT MOUNTING SEQUENCE! 4

8 Connection & use 15. Connection & use Black K4401 9V 9V BATTERY ON/OFF OUT LS Red Turn the potentiometer to its centre position. Connect a loudspeaker (8 ohm / 1Watt min.) between the points LS. Connect a power supply (9VDC) or a 9V battery between the points 9V and 9V. Pressing the different push buttons now causes the respective effects to be produced. ATTENTION: With some of the effects (e.g. sirens, car engine) it's necessary to keep the push button pressed. The speed of the effects can be changed (optimized) by turning the potentiometer. Fig. 1.0 LOUDSPEAKER 8 OHM / 1 WATT LINE OUT The OUT output allows you to extra amplify the sounds or to connect them to a mixing panel. In this case you possibly can disconnect the loudspeaker. Thanks to the position of the push buttons and of the potentiometer, this circuit can be built into a plastic housing or the pcb be mounted behind a panel very easily. Loudspeaker & on/off switch are not included! 8
