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 sol-

der rolls off the tip, it needs cleaning.

•Thin raisin-core 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 can-

not 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 multi-meter is required, or might be

handy

1.2 Assembly Hints :

þMake sure the skill level matches your experience, to avoid disappointments.

þFollow the instructions carefully. Read and understand the entire step before you perform each operation.

þPerform the assembly in the correct order as stated in this manual

þPosition all parts on the PCB (Printed Circuit Board) as shown on the drawings.

þValues on the circuit diagram are subject to changes.

þValues in this assembly guide are correct*

þUse the check-boxes to mark your progress.

þPlease 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.

1.3 Soldering Hints :

Mount the component against the

PCB surface and carefully solder the

leads

Make sure the solder joints are

cone-shaped and shiny Trim excess leads as close as pos-

sible to the solder joint
