Troubleshooting
Chapter

will
help
you
identify
the
source
of
most
problems
that
can
occur
with
the
Mobile
Digital
Power
Inverter.
If
you
have
a
problem
with
the
inverter,
please
review
this
chapter
before
contacting
your
dealer.
Buzz
in
Audio
Equipment
Some
inexpensive
stereo
systems
may
emit
a
buzzing
noise
from
their
loudspeakers
when
operated
from
the
Mobile
Digital
Power
Inverter.
This
occurs
because
the
power
supply
in
the
audio
system
does
not
adequately
filter
the
modified
sine
wave
produced
by
the
inverter.
The
only
solution
is
to
use
a
sound
system
that
has
a
higher
quality
power
supply.
Television
Reception
When
the
Mobile
Digital
Power
Inverter
is
operating,
it
can
interfere
with
television
reception
on
some
channels.
If
interference
occurs,
try
the
following:
1.
Make
sure
that
the
television
antenna
provides
an
adequate
(“snow
‐
free”)
signal,
and
that
you
are
using
good
quality
cable
between
the
antenna
and
the
television.
2.
Keep
the
cables
between
the
battery
and
the
Mobile
Digital
Power
Inverter
as
short
as
possible,
and
twist
them
together
with
two
to
three
twists
per
foot.
(This
minimizes
radiated
interference
from
the
cables.)
3.
Move
the
television
as
far
away
from
the
Mobile
Digital
Power
Inverter
as
possible.
4.
Do
not
operate
high
power
loads
with
the
Mobile
Digital
Power
Inverter
while
the
television
is
on.
