The DEQ-230’s detachable control panel design greatly simplifies system tuning. It
allows real time adjustment of system equalization from the front seat or outside the
vehicle.In order to oper ate the DEQ-230 in this mode, simply remo v e the Allen head scre w
(located to the right of the thumb notch on the front bezel) that holds the main control panel
to the docking bay, and carefully remove the main control panel.You will notice that it is
connected to the docking bay via a short eight conductor phone cord. Make sure that the
power is off! Remove the control panel, disconnect the short cord at both ends and then
replace it with the 20 ft. cable (supplied). After plugging the control panel into the docking
bay, turn power back on, and begin your pink noise analysis, or make final adjustments to
sound quality from the front seat.

NOTE: Before beginning, disconnect the negative (-) terminal of the battery prior to
working on the positive (+) terminal to prevent an electrical 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.
To prevent damage to the equalizer 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 include the trunk and passenger compartment (floor or
under seat). Never mount the equalizer in a location that would subject it to immersion or
exposure to water.
Once a location has been chosen, securely mount the DEQ-230 with four mounting
screws.Be Careful! Inspect the area underneath to be sure you are not drilling into
wires, brake or fuel lines, etc.that could be damaged by the drill bit or screws.
