Mi OPERATION
Note: Turn the amplifier on, and set it for listening to the sound.
(Refer to the operating instructions of the amplifier.)
Because as many as six types of equalization curves can be stored in the memory of this unit, tone quality adjustments according to each
tune can
be made
in fine detail and very easily.
1
Reduce the volume level of the
amplifier.
Set the amplifier's tone controls to the center
(rston and set the super bass switch to
"QFF".
2
Set the power switch to '"ON''.

"MOST RECENT" memory
If, after the buttons and equalization levels of this unit have been
set, the power is switched to STANDBY
and then switched ON,
the setting of each
button and the equalization
levels will be
entered into the memory, and these settings will return when the
power
is switched
ON.
Memory back-up
Lithium
batteries are used to retain the data stored
in the
memory,
thus safeguarding the memory entries made by the
various
buttons,
as well as the equalization
curves
of the
equalization display, or curves
stored in the memory,
even
if
there is no power
to this unit.
A word about the lithium batteries
This unit employs lithium batteries for back-up of the memory if a
power failure occurs, but these batteries will no longer provide
that back-up
if they become
weak.
If battery replacement is necessary, consult with the store where
the unit was purchased, or any store where Technics products
are sold, or an authorized
Service Center (see enclosed
list).

graphic equalizer.
First, display the curve
used when the
recording was made.
