Getting Started
The fastest way to get started is to take your time and do everything
right the first time. Take a few minutes now to click through the CD-
ROM and review the user’s manual. This may save you time later on.
At the beginning of each section of the manual you’ll find an over-
view. If the section doesn’t apply, you can skip it.
