The disc is best checked for flatness by
placing it on a smooth, flat surface, such as
a mirror or a pane of glass. Try to slide a
dime underneath the inside and outside
edges. If a dime will slide, the disc is warped
beyond the 3mm tolerance and should be
replaced before it causes you any focus
headaches.
7. Do not operate the disc player outside its
environmental specifications. The big
concerns in laser games are that temper-
ature be between 45 and 95°F, and humidity
does not exceed 80% non-condensing.
This means extra care will be required
during winter cold and summer heat. Some-
times disc players will require hours of
stable environment before condensation
has dissipated and operation returns to
normal. If a disc player or laser game is
moved from cold to hot, or vice versa, give it
plenty of time to become thermally stable
before even attempting to run it.

Next time, the focus will be laserdisc player

8. Try not to let the jargon, or the special
requirements, get you down. These eight
points should clear up perhaps 40% of the
usual disc player complaints. Soon, by
reading these articles, you will be able to
strip a disc player, diagnose the faults with
its innards, and leap tall buildings!
The above list of guidelines is by no means
exhaustive, but short of actual repair, you
should find the guidelines applicable to all
laser games, and that the use of these guide-
lines should make a large dent in the number
of laser game service calls you are performing.
Make sure your operators have a good under-
standing of what's required to keep these
laser games running, and we'll all be happerl
