5. Final Assembly Manual ELECTROVOCE www electrovoce com l IMPORTANT NOTES BEFORE BEGINNING O A Failure to take ESD precautions could permanently damage the components ESD damage is permanent and invisible to the naked eye Zapped parts are terribly difficult to find once they are assembled into your MIDItools Computer Although it is best to always wear your ESD ground strap while assembling your kit all assembly steps that require ESD protection are marked with this symbol in the margin B All ribbon cable connectors are polarized This means that they must be installed only in the orientation shown on the layout diagram All assembly steps that pertain to polarized or directional connectors are marked with this symbol in the margin Incorrect orientation can damage components C This manual refers to the TOP BOTTOM LEFT or RIGHT sides of circuit boards or enclosures These directions correspond to the item being held as shown in the layout diagrams Il SET UP YOUR WORK AREA A Your work surface should be well lit and well ventilated B Gather your tools ESD grounding strap soldering iron solder noncorrosive electronics solder wire cutters screwdrivers phillips and pan head pliers etc C Prepare ESD grounding protection A typical ESD ground strap is adequate Put the strap around your wrist and clip the other end to the head of a slightly loosened screw of a working grounded AC outlet plate The strap
