Please unpack the system carefully!  This unit is heavy.  Use caution when lifting or moving to
avoid injury. Remove all staples if used to seal the carton as they can scratch the cabinet.
Please save the carton and all packaging materials for future use.  Packing this unit in any other
carton may result in severe damage when shipping.  Please take a moment to record the serial

Caution!
This subwoofer has electronics built into the cabinet.  Do not place the cabinet next to
sources of heat such as furnace registers, radiators, etc.  Do not place the unit near
sources of excessive moisture, such as evaporative coolers, humidifiers, etc.  The power
cord should be routed in such a way that it will not be walked on, pinched, or
compressed in any way that could result in damaging the insulation or wire. 

Regardless of where you install your Velodyne subwoofer, it must remain in an upright position
(woofer facing forward).  Using, shipping, or otherwise storing the subwoofer in any other
position for an extended period of time may result in damage to the unit not covered
by warranty.

Certain types of televisions are particularly sensitive to stray magnetic fields.  If your television
produces distorted colors after installing your subwoofer, simply increase the distance between
your television and the subwoofer, until normal color and operation is returned. 

Important Note:  Turn your subwoofer off before moving it!
