SERVICE

Do not attempt to service PPI products yourself. Performing exploratory
surgery on your audio equipment yourself will void the warranty. All parts of
your PPI gear have been built to our specifications. These parts are not
made available to any unauthorized PPI dealer nor are they for sale. Our goal
is to make sure that your PPI product will always perform as good as the day
it was purchased. Contact your authorized PPI dealer about obtaining any
warranty service through PPI. (See Warranty inside back cover.)

CAUTION!

The extended use of a high powered audio system may result in hearing loss
or damage. While PPI systems are capable of "Concert Level" volumes,
they are also designed for you to enjoy at more reasonable levels all of the
creative expressions made by musicians. Please stay seated while driving
and observe all local sound ordinances.

To prevent damage to the PPI-EQP while driving, mount it in a secure

place. Choosing the appropriate location will depend upon your vehicle and
the complexity of your system design. Typical mounting locations for your
new PPI-EQP would be in the dash or center console. Never mount the
component in a location that would subject it to immersion or exposure
to water.

Once a location has been chosen, securely mount the PPI-EQP using the

two supplied brackets. The brackets are connected to the equalizer/preamp
by two 3mm x .5mm x 6mm phillips head screws. We have made the
brackets adjustable to compensate for the uniqueness of each vehicle. Be
Careful! Inspect the area underneath to be sure you are not drilling into wires,
etc. that could be damaged by the drill bit or screws.

Before beginning, disconnect the negative (-) terminal of the battery prior
to working on the positive (+) terminal to prevent a short to ground.
This is important, unless you want to spend the rest of your life with a
nickname like "Sparky," or "Smokey." Reconnect the negative terminal
only after all connections have been made.
