Montana (and maybe your state, too)
has problems with not being able to produce good
earth ground connections because of low earth resistivity
What this means is that the AC lines into the
location maybe noisy due to a difference in earth
ground resistMty. Or may be noisy at times of
high atmospheric electrical resistivity. Or may
be noisy at times of high atmospheric electrical
activity 0ightning storms). This, of course, varies
from place to place, as to the severity of the
resistivity problem.
Static Probe (noise inducer) to the AC input of
the CD-100, however, message errors 05-62, 05-
63, 14-05, and "OUT OF ORDER" occurred.
Also, the current song being played would be
rejected randomly during the testing. The modi-
fication Rowe recommended didn't seem to
make a difference (the modification I tried on
location didn't seem to help either).
They also stated, "brown-outs" (AC voltage below
100 volts) are unlikely, but they did not state
that we were protected against them either (an-
other possibility).
RESULTS
Since the Rowe modification didn't seem to help,
we went with a Line Stabilizer/ Conditioner
(spike protector with under-voltage protection).
This has eliminated the problems we were hav-
ing, we even placed the CD-100 at our worst AC
power location with no problems.
TEST RESULTS
All this information seemed obscure and remote
but, it was helpful. After testing a CD-100 in the
shop for a couple of weeks, I found the following
information:
CHOICE
You may want to go cheaper if you can, by buying
just a spike protector ($40.00), instead of the
Line Stabilizer/Conditioner ($130.00). The only
advantage of the Line Stabilizer/Conditioner is
the under-voltage protection. I hope this solves
those annoying problem locations.
The CD-100 ran fine in the shop (3-4 days)
without errors even when exposed to neon light.
No noticeable change in CD-100 performance or
even any errors occurred. When I applied a
