TSG 90 PATHFINDER Service Manual
The PATHFINDER contains electrical components that are susceptible to dam-
age from static discharge. Static voltages of 1 kV to 30 kV are common in un-
protected environments.
CAUTION.
Static discharge can damage any semiconductor component in this
instrument.
Observe the following precautions to avoid static damage:
H
Minimize handling of static-sensitive components.
H
Transport and store static-sensitive components or assemblies in their
original containers, on a metal rail, or on conductive foam. Label any
package that contains static-sensitive assemblies or components.
H
Discharge the static voltage from your body by wearing a wrist strap while
handling these components. Servicing static-sensitive assemblies or
components should only be performed at a static-free workstation by
qualified personnel.
H
Nothing capable of generating or holding a static charge should be allowed
on the workstation surface.
H
Keep the component leads shorted together whenever possible.
H
Pick up components by the body, never by the leads.
H
Do not slide the components over any surface.
H
Avoid handling components in areas that have a floor or work surface
covering capable of generating a static charge.
H
Use a soldering iron that is connected to earth ground.
H
Use only special antistatic, suction-type or wick-type desoldering tools.
Troubleshooting Aids
The following is miscellaneous information about schematics, circuit board il-
lustrations, component numbering, and assembly numbering.
NOTE
. No repair should be attempted during the warranty period.
The foldout pages at the back of the manual contain block and schematic dia-
