For optimum performance, the temperature of the operating environment should be between +5º C to +35º C (+41º F - +95º F). Fail-
ure to maintain proper operating temperature may result in difficulty reading the display, thermal overload, or systemwide instability.
Avoid exposing the unit to direct sunlight. When placing the unit in an installation, make sure that it is placed on a stable surface, as
far away from vibrations as possible. Even though the unit is impervious to vibration, the storage devices (specifically hard drive-
based ones) that are designed to be used in conjunction with it may not be. Also, be sure not to place or use the SDJ-4000 on heat
generating sources, such as amplifiers or near spotlights.

Before you begin using your new SDJ-4000, you're going to want to have a USB flash drive prepared with some music. As long as
the USB drive is formatted in FAT32 and the songs on it are compatible with the SDJ-4000, then you'll be able to play them back and
even use some of the more advanced features of the SDJ-4000. To truly take advantage of all the power the SDJ-4000 has to offer,
you'll want to prepare your library using Gemini's free V-CASE Library Management software. V-CASE will not only process the BPM
and key of your music, it will render the waveforms, store track data (like cue points, beat grids, playlists, etc.), and enable features
like track sync, tempo-based effects, and more. V-CASE also makes it possible to create playlists and perform bulk analysis on large
libraries. So, let's take a minute to talk about V-CASE and how it works.
The first thing you'll need to do after you install V-CASE is to add some music into your track library. You can drag and drop or select
the music by navigating to it using the explorer panel. If you keep all your music in a single directory, it may be easier to import the
whole folder by going to FILE>IMPORT>Import Folder
Once you have a few songs in your library, you'll need to analyze them to calculate BPM, key, etc. When your tracks are analyzed,
load one into the V-CASE player. Now verify that the beat grid is aligned with the first beat of the song, and that the BPM looks cor-
rect. If the beat grid is misaligned, you can use the move tools to place the beat grid where you want it. To verify proper placement,
a metronome is also available (each "tick" indicates a grid marker crossing the play marker). This would also be a good time to add
a few cue points. There are up to 8 available cue points per track. Once you've set up your tracks, you can create playlists by select-
ing a group of tracks, right-click them, and select "Create playlist from selection". Finally, you can export music from your V-CASE
library to a USB flash drive by selecting a group of tracks or a playlist and choosing the EXPORT option from the right-click menu.
it's important that you understand the basics of V-CASE, because once your music is processed by V-CASE, you can unlock the full
potential of your SDJ-4000.
