WARNING – READ THIS FIRST!
All personnel involved with the installation, operation, or maintenance of the equipment described in this
manual should read and understand the warnings and recommendations provided below.
Static Sensitive Devices
This equipment contains devices that are extremely sensitive to static electrical charges and could be
damaged by static electricity present on the body and clothing. Normal handling precautions involve the
use of anti-static protection materials and grounding straps for personnel.
Radiation
This equipment radiates radiofrequency energy that can cause interference with radio communications.
The equipment has not been tested for compliance with the appropriate FCC rules designed to provide
reasonable protection against such interference when operated in a commercial environment. When
operating the equipment in a residential area, the user may be required to take whatever measures are
needed and incur any expenses necessary to eliminate interference. It is the user's responsibility to verify
that the system complies with the applicable FCC emission limits.
High Voltages
Use caution when the electronics are removed from their containers for servicing as high voltage is
present in parts of the system when powered on.
Improper Line Voltage
Operation with improper line voltage may cause serious damage to the equipment. Always ensure that
the proper line voltage is used.

HARDWARE VARIATIONS AND COMPATIBILITY
The 4200 Side Scan Sonar System contains both standard PC and proprietary hardware. At times EdgeTech
may change the standard components due to their availability or performance improvements. Although
the component manufacturers, along with their models and styles may change from unit to unit,
replacement components will generally be interchangeable.
EdgeTech will make every effort to see that replacement components are interchangeable and use the
same software drivers. At times, however, direct replacements may not exist. When this happens,
EdgeTech will provide the necessary drivers with the replacement part.
EdgeTech may also change certain hardware per customer requirements. Therefore, portions of this
manual, such as parts lists and test features, are subject to change. These sections should be used for
reference only. When changes are made that affect system operation, they will be explicitly noted. Also,
some options and features may not be active in the customer’s unit at the time of delivery. Upgrades will
be made available when these features are implemented.
