Rowe CD-100 AC Noise Proble1ns
Do you have locations that complain about not getting to hear all the songs they played? But,
when you get to the location the CD-100 is playing fine (or maybe a 05-62 or 05-63 error
logged}. You've tried changing the Mech. Controller and the CCC (computer board} and still
they complain. ARE THEY CRAZY, DRUNK, OR STUPID? Maybe not.
SUBJECT
For sometime now
we have been having
random 05-62 or 05-
63 errors occurring
in 4 of our 15 Rowe
CD-100 Jukeboxes.
These errors are
caused by a commu-
nications failure be-
tween CMD-3 (or CD
player) and the Me-
chanical Controller
(or Mech. Control-
ler).
FACTORY SOLUTION
Rowe maintains that
these errors are
caused by a noisy AC
input. This may be
ca used by either
neon lights, com-
pressors, or noisy
AC power from your
local power com-
pany. They recom-
mend a small circuit
to be added to the
wiring harness. This
is suppose to elimi-
nate the 05-62 and
05-63 errors by re-
setting the Mech.
Controller when
there is a voltage
spike on the +5 volt
de line that supplies
L'le CD player.
EARTH GROUND
I also talked with an
engineer at our local
power
company
about noise prob-
lems. Though they
were less than in-
sightful. I did man-
age to ascertain that
Montana
(and
maybe your state,
too) has problems
with not being able
to produce good
earth ground con-
nections because of
low earth resistivity,
or not being able to
drive 8 foot earth
ground spikes.
