1 - We're earning our money on this install. VERY difficult to get to appropriate components.
2 - DIY possible, but not recommended. Many components to remove and tap points still difficult to get to.
All surface mount - Means all points tapped in the player are on legs of surface-mount components, requiring a fair knowledge of soldering.
Mostly jumpers - Means points tapped are wire jumpers and are generally the easist solderable points.
Remove (X) Boards - Circuit boards inside the player must be carefully removed to get to points on other boards beneath them.
