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 (25-40W) 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 raisin-core solder. Do not use any fl ux or grease.

•  

A diagonal cutter to trim excess wires. To avoid injury when cutting excess  leads, hold the lead so they cannot 

•  

fl y towards the eyes.
Needle nose pliers, for bending leads, or to hold components in place.

•  

Small blade and Phillips screwdrivers. A basic range is fi ne.

•  

For some projects, a basic multi-meter is required, or might be handy

 

1.2 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, the values in this assembly guide are correct*

•  

Use the check-boxes 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 leafl et.  

1.3 Soldering Hints :
