To clean the MDJ-900, use only a dry soft cloth and/or
compressed air. If the unit is soiled with stubborn dirt, we suggest
using a 2:1 solution of distilled water and 30% isopropyl
alcohol. Avoid using harsh cleaning chemicals such as benzene,
paint thinner, bleach, or hydrochloric acid, which will damage
the unit

For optimum performance, the temperature of the operating
environment should be between +5º C to +35º C (+41º F - +95º
F). Failure to maintain proper operating temperature may result
in difficulty reading the display, thermal overload, or system
wide 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 devices) that
are designed to be used in conjunction with it are typically not.
Also be sure not to place or use the player on heat generating
sources, such as amplifiers or near spotlights.

When placed in MIDI mode, the MDJ-900 can send MIDI data
from the buttons and dials to a computer to control the
parameters and playback controls of DJ software. The audio
playback from the computer can also be output from the
MDJ-900.
Before using the MDJ-900 as an audio device, connect the
MDJ-900 with a USB cable and allow your PC/MAC to detect
it. Open your DJ software and select the MDJ-900's output
device in the DJ software's settings. For instructions on how
to do this, see your DJ software's operating instructions.
