H.F. RADIATION
can cause
interference.
High-frequency (H.F.)
can
interfere with radio
navigation, safety
services, computers,
and
communications
equipment.
Have
only qualified
persons familiar with
electronic
equipment perform
this installation.
The
user
is
responsible
for
having
a
qualified
electrician
promptly
correct
any interference
problem resulting
from the
installation.
If
notified
by
the FCC about
interference, stop
using
the
equipment
at
once.
Have the installation
regularly
checked and maintained.
Keep high-frequency
source
doors and
panels tightly
shut,
keep spark
gaps
at correct
setting,
and
use
grounding
and
shielding
to minimize
the
possibility
of interference.
ARC WELDING
can cause
interference.
Electromagnetic
energy
can
interfere with
sensitive
electronic
equipment
such
as
computers
and
computer-driven equipment
such
as
robots.
Be
sure
all
equipment
in the
welding
area
is
electromagnetically compatible.
To reduce
possible
interference, keep
weld cables
as
short
as
possible,
close
together,
and down
low,
such
as
on
the floor.
Locate
welding operation
100 meters from
any
sensitive elec
tronic
equipment.
Be
sure
this
welding
machine is installed and
grounded
according
to
this manual.
If interference still
occurs,
the
user
must take extra
measures
such
as
moving
the
welding
machine,
using
shielded
cables,
using
line
filters,
or
shielding
the work
area.
