Unpacking
The HCA-2200II is packed in two strong cardboard cartons. Save your cartons and the styrofoam inserts for
future safe transport in case you move or the unit ever requires shipping for repair. Note, the inner printed
carton is not itself strong enough for safe shipping, so you absolutely must place it into the additional outer
"overcarton" before shipment.
To remove the unit, you may use the handles at front and rear to balance its weight. You may findit easier if
you first rest the unit on its rear handles so you can change your grip before moving it to its correct horizon-
tal position. Take care not to cut or scratch yourself on the exposed extruded metal heatsinks on either side
of the unit.
The AC cord is packed separately in the carton. This is a specially selected audiophile grade cord and is the
only cord we recommend for use with the HCA-2200II. Please don't lose it.
Before you proceed, find the serial number which is located on the rear panel ofthe unit and record it here for
future reference or in case of casualty loss or theft:________________
Warning:To prevent fire or shock hazard, do not expose this unit to rain or moisture.
