HARDWARE VARIATIONS AND COMPATIBILITY
The 2000-DSS Combined Sonar contains both standard 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 parts will generally be interchangeable.
EdgeTech will make every effort to see that replacement components are interchangeable and use the
same software drivers (if applicable). At times, however, direct replacements may not exist. When this
happens, EdgeTech will provide the necessary drivers with the replacement part, if applicable.
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 time of delivery. Upgrades will be
made available when these features are implemented.
Contact EDGETECH CUSTOMER SERVICE with any questions relating to compatibility.

RETURNED MATERIAL AUTHORIZATION
Prior to returning any equipment to EdgeTech, a Returned Material
Authorization (RMA) Number must be obtained from CUSTOMER SERVICE.
RMA Purpose
The RMA Number identifies returned equipment when it arrives at our receiving dock and enables tracking
while at our facility. Refer to RMA number on all documentation and correspondences.
All returned materials must be shipped prepaid. Freight collect shipments will not be accepted. All
equipment should be adequately insured for shipping, but equipment belonging to EdgeTech must be
insured for full value.
If there is more than one item per consignment, include a packing with the shipment. An invoice can
double as a packing slip only when the contents are clearly numbered and identified on the invoice.
CAUTION! Never attempt to ship a Portable Topside in its Storm CaseTM
alone. Although rugged, these cases are not intended to be used as
shipping containers and the delicate internal components could be
damaged. Shipping in this manner will void any warranties.
NOTE: All shipping charges shall be the responsibility of the customer,
unless under warranty, as EdgeTech will pay for return shipping.
NOTE: For International Shipments valued over $1000, the following
