WARNING: The Samsung DS 616 system contains many static sensitive
components. To reduce the incidence of premature equipment failure, observe the
following precautions.

(PCB's) and wear an anti-static wrist strap connected to the KSU earth lug.
• Always handle boards by the edges.
• Never touch PCB tracks or connectors. Contaminants introduced by fingers can
cause corrosion and high resistance connections.
• Never touch or straighten components, especially the ceramic sub-assemblies.
They are physically delicate and finger pressure can fracture component leads
(even if the leads do not actually break).
• To protect PCBs against physical damage and damage due to static discharge,
always wrap them in an anti-static bag and replace them in the packaging provided
with the new item.
WARNING: Power must be switched OFF before any cards are removed or
