1. The
unit
and the speaker
will
be
damaged
if
there
is
a connet::tion
to
the
ground
(chassis)
from
any speaker wire.
2.
For best result, speakers should
be
rated
to
safely handle the additional power
output
provided
by
the
unit
speakers
with
low
power rating may
be
damaged.
3. This equipment
is
intended
for
use
in
12V
DC negative ground electrical system
only. The
use
of
voltage
or
polarity
converters
is
discouraged.
4. To avoid the possibility
of
short-circuiting the
output
stages
both
radio and
the
amplifier
should
be
switched-off (preferably disconnected
from
the
power
supply) when installing and
wiring
the
speakers.
5.
Use
high
or
low
level inputs
to
the equalizer. Both can-not
be
connected at the
same
time.

CARE AND MAINTENANCE
Your Pyramid 300 Watt Stereo 10-Band
Equalizer/Booster is
an
example of
superior design and craftsmanship.
The following suggestions will help you
care for your equalizer/booster
so
you
can enjoy
it
for years.
Keep
the equalizer/
booster
dry,
If
it
does
get wet, wipe
it
dry im-
mediately. Liquids con-
tain minerals that can
corrode electronic cir-
cuits.
Keep
the equalizer/
booster away from dust
and dirt, which can
cause premature wear
of parts.
@
Wipe the equalizer/
)\
booster with a damp
,I
"'
,"
cloth occasionally to
. . keep
it
looking
new.
Do
not
use
harsh chemi-
cals, cleaning solvents,
or strong detergents to
clean the equalizer/
booster.
(:j

./
'-
I"
'
Use and store the equal-
izer/booster only
in
nor-
mal
temperature envi-
ronments. Temperature
extremes can shorten
the life of electronic de-
vices and distort or melt
plastic parts.
Handle the equalizer/
booster gently and care-
fully.
Dropping
it
can
damage the circuit
boards and can cause
it
to work improperly.
