LOCATION
Avoid placing your AX-400/U in direct sunlight or
close to a source of heat. Also avoid locations in
which the device is likely to be subjected to exces-
sive dust, cold or moisture.
VENTILATION
The openings on the cabinet ensure the ventilation |
of the amplifier. ff these openings are obstructed,
the temperature inside the cabinet will rise rapidly
and eventually damage the circuits. Therefore, avoid
placing objects against these openings and do not
install your amplifier in a place such that the flow
of air through the ventilation openings could be im-
peded.
HANDLING
@ Power cord
When removing the power plug from the wall outlet,
always pull directly on the plug. Never yank the cord
as this may result in damage to the cord and possibly
a short-circuit.
If you do not intend to use this unit for an extended
period of time, it is advisable to unplug the power
cord.
® Switches and knobs
Avoid applying excessive force to the switches and
knobs.

Before moving your amplifier, be sure to unplug the
