5. CARE
Wipe the cabinet with a soft cloth when it becomes
dusty.
If it should get really dirty, dampen
a soft
cloth
in a weak
solution of mild soap and water,
wring it out dry and wipe off. When finished, dry
completely with a soft dry cloth. Any volatile ma-
terials such as alcohol, thinner, benzine, insecticides,
etc, may remove the paint or damage the luster and
should not be used.

1. THERMAL
INDICATORS
lf the temperature
of the heat sink reaches 60°C
(140°F), the thermal indicators change in color from
red to black.
If the indicators turn black, turn the
power off and allow time for the amplifier to cool.
Resume operation when the amplifier cools to nor-
mal temperature.
