Safety Warnings

Warning: Operating the DNA Engine
constitute a personal injury hazard. Only qualified laboratory personnel
trained in the safe use of electrical equipment should operate these
machines.
Warning: Do not open or attempt to repair the DNA Engine or any Alpha
unit, or other DNA Engine accessory. Doing so will void your warranties and
can put you at risk for electrical shock. Return the DNA Engine instrument to
the factory (US customers) or an authorized distributor (all other customers) if
repairs are needed.
Warning: All Alpha unit blocks can become hot enough during the course of
normal operation to cause burns or cause liquids to boil explosively. Wear
safety goggles or other eye protection at all times during operation.
Warning: The DNA Engine instruments incorporate neutral fusing, which
means that live power may still be available inside the machines even when a
fuse has blown or been removed. Never open the DNA Engine or DNA Engine
Tetrad base; you could receive a serious electrical shock. Opening the base
will also void your warranties.
Caution: Never remove an Alpha unit from the DNA Engine with the power
turned on and a program running. Doing so can cause electrical arcing that
can melt the contacts in the connector joining the Alpha unit to the DNA
Engine.
