SveERSoN1c PAGE ERRORS,
PROGRAMMING AND NEW AMP HEATSINK
Greetings Star Tech readers!
Sorry I missed you last month.
Even us technical types need a
vacation now and then. Actually
I was on the road meeting with
Rock-Ola Distributors and Op-
erators.
This month's first item will cover
an issue brought to my attention
while in Chicago. By the way, if
any of you would like a specific
item or topic covered, contact me
via Star Tech Journal or e-mail. ..
mrjuke@earthlink.net
Meeting with many of you gave
me the opportunity to find out
first hand your concerns and the
kinds of difficulties you guys and
gals run into. In the coming
months I will address many of
these issues.
SYBERSONIC PAGE ERR.ORS
I was also asked to be more de-
tailed when giving programming
instructions. So now whenever
programming issues are dis-
cussed, I will include the "key-
strokes" as well as examples of
what will be seen in the key-
board/ display.
Our service center received sev-
eral calls for replacement
SyberSonic computers due to dis-
play pages not working. In most
cases no problem was found with
the computer. What actually
happened was the Page Options
were programmed while the
page unit was not installed.
Whenever the Page Options
(Quick Find 25, 26 or 27) are set,
the SyberSonic Computer
"looks" for the last page by run-
ning the pages back and forth.
Because the computer senses the
pages are not present (they're
unplugged!), it automatically sets
the Last Page to 0. If set to 0,
the pages will not move when the
Turn Pages buttons are pressed
because the computer believes
that it shouldn't move them.
To correct this, simply plug the
pages back in and set Last Page
(Quick Find 26) to 06 if in a
SyberSonic Legend or to 16 if in
a SyberSonic Rocket. It is not
necessary to set Last Page in a
Nostalgic SyberSonic Jukebox
with version 3.2 and above soft-
ware. (Also see 3.2 Software Up-
date on page 6 of Star Tech Jour-
nal, May 1997.)

This heat has to be dissipated to
prevent overheating of its own
components as well as the elec-
tronic devices that share a cabi-
net with it. In fact, a CD M-12
player can start skipping as low
as 110 degrees F. The more heat
you can vent out of the cabinet
the better the machine will oper-
ate.

With that in mind we designed a
brand new heatsink for our 360
Watt SyberSonic Amplifier. Be-

heavy duty fins, it more effi-
Service Tip: If you want to test the
Syber Sonic computers' response to the
page unit drive motor and opto-sen-
sor, set Last Page to 99 then press
HITS. Once the pages stop moving
check to see if the Last Page reset it-
self to the proper value. If it did not,
check the opto-sensor, opto-sensor
harness and page unit harness.
NEW AMPLIFIER IIEATSINK
Rock-Ola Manufacturing is con-
stantly looking for ways to im-
prove our product line. We've
just introduced another perfor-
mance enhancement that may go
unnoticed but is important none-
theless. I know this news will
have you all jumping out of your
seats! OK, so it's not that excit-
ing, but please read on anyway.
You know that heat is an enemy
to most electronic components.
One of the keys to the long life
of any electronic device is to keep
it as cool as possible. Amplifiers
produce a great amount of heat.
Take advantage of this before
Glenn comes back to his
senses!
ciently removes heat from the
cabinet because it has three more
fins to give it more radiation area
In fact, our new heatsink exceeds
the standard for efficiency and
safety. All this means the cabinet
is cooler and the jukebox will be
even more reliable.
Our original heatsink was ex-
truded aluminum with steel side
brackets to mount the driver
boards and the amplifier to the
cabinet. The new heatsink is a
one piece die-cast aluminum unit.
Designing and building the new
heatsink took a lot of time and
money, over $40,000 for tooling
alone. By making the new part a
one piece design, we were able
to eliminate the two side mount-
ing brackets and hardware. Also,
the amplifier is now mounted
directly to the cabinet.
Fewer components, simpler de-
sign and more efficient are all
parts of the Rock-Ola KISS Prin-
ciple. Talk about a win .. . win situ-
ation!
