Keep the unit away from naked flames, radiators, heat registers, stoves, or any
other heat-producing appliances (including amplifiers).

The unit has been designed for use in moderate climates. Do not attempt to use
below 41 degrees Fahrenheit (5 degrees Celsius) or above 95 degrees Fahrenheit
(35 degrees Celsius).

Place the unit on a fixed, level surface strong enough to support its weight. Do
not place it on a moveable cart that could tip over. We recommend only using
stands approved for use with audio equipment.

Unplug the unit from the mains supply before cleaning. The case should normally
require only a wipe with a soft lint-free cloth.

Only connect the unit to a power supply of the type and voltage described in the
operating instructions or specified on the rear panel of the unit.

Connect the unit to the power outlet only with the cord supplied. Do not modify
the supplied cable in any way.

Do not attempt to defeat grounding and/or

polarization provisions. Do not use extension cords. Do not route the power cord
where it will be crushed, pinched, bent at severe angles, exposed to heat, or
damaged in any way.

If the unit is to be left unused for a long period of time, the power cord should be
unplugged from the wall outlet.
