WARNING
: The Samsung DS 616 system contains many static sensitive
components. To reduce the incidence of premature equipment failure, observe the
following precautions.
•
Always discharge static from yourself before handling any Printed Circuit Boards
(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
installed.
