NOTE:
Oren.
Any
change
in
powerline
frequency
will
cause
a
change
of
the
fluctuation
rate
of
the
neon
or
fluorescent
lamp
used
for
the
illumination
of
the
strobe
dots.
In
such
acse
the
strobe
dots
will
start
to
move
very
slightly.
Under
normal
conditions
the
powerline
frequency
from
Electric
Utility
Companies
is
extremely
stable.
Under
certain
abnormal
conditions,
however,
changes
in
line
frequency
have
been
observed,
averaging
to
about
0.2
%
when
measured
over
a
period
of
time.
|
Such
change
in
line
frequency
will
in
no
way
affect
the
quality
of
the
sound
