Pioneer DJM-800 User Manual

Install the unit in a well-ventilated location where it will not
be exposed to high temperatures or humidity.
÷ Do not install the unit in a location which is exposed to

direct rays of the sun, or near stoves or radiators. Excessive
heat can adversely affect the cabinet and internal
components. Installation of the unit in a damp or dusty
environment may also result in a malfunction or accident.
(Avoid installation near cookers etc., where the unit may be
exposed to oily smoke, steam or heat.)

÷ When the unit is used inside a carrying case or DJ booth,

separate it from the walls or other equipment to improve
heat radiation.

÷ Use a polishing cloth to wipe off dust and dirt.

÷ When the surfaces are very dirty, wipe with a soft cloth

dipped in some neutral cleanser diluted five or six times
with water and wrung out well, then wipe again with a dry
cloth. Do not use furniture wax or cleaners.

÷ Never use thinners, benzene, insecticide sprays or other

chemicals on or near this unit, since these will corrode the
surfaces.

Selecting fine audio equipment such as the unit 

you’ve just purchased is only the start of your 
musical enjoyment. Now it’s time to consider how 
you can maximize the fun and excitement your 
equipment  offers. This manufacturer and the 
Electronic Industries Association’s Consumer 
Electronics Group want you to get the most out of 
your equipment by playing it at a safe level. One that 
lets the sound come through loud and clear without 
annoying blaring or distortion-and, most importantly, 
without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing 

“comfort level” adapts to higher volumes of sound. 
So what sounds  “normal” can actually be loud and 
harmful to your hearing. Guard against this by 
setting your equipment at a safe level BEFORE your 
hearing adapts.

To establish a safe level: 
•  Start your volume control at a low setting.
•  Slowly increase the sound until you can hear it 

comfortably and   clearly, and without distortion.

Once you have established a comfortable sound 
level:
•  Set the dial and leave it there.

Taking a minute to do this now will help to prevent 

hearing damage or loss in the future. After all, we 
want you listening for a lifetime.

Used wisely, your new sound equipment will 

provide a lifetime of fun and enjoyment. Since 
hearing damage from loud noise is often 
undetectable until it is too late, this manufacturer 
and the Electronic Industries Association’s 
Consumer Electronics Group recommend you avoid 
prolonged exposure to excessive noise. This list of 
sound levels is included for your protection.
