4, OPERATIONS
BEFORE PLACING THE POWER SWITCH IN THE
ON OR OFF POSITION OR OPERATING
SWITCHES, ALWAYS TURN THE PREAMPLI-
FIER’S VOLUME (ATTENUATOR) CONTROL
ALL THE WAY DOWN
This is to protect the speakers from damage, that
can occur if the volume level is set high and the
power is turned on.
THERE WILL BE NO SOUND FOR A FEW SEC-
ONDS AFTER YOU TURN ON THE POWER.
THIS IS NOT A MALFUNCTON
This unit is equipped with a power supply muting
circuit which prevents popping noise when the pow-
er switch is turned on or off.
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.
