CAUTION
As this unit is intended to interface with other electrical/electronic systems, proper
engineering practices must be adhered to during installation and check-out.
All AC power and ground must be installed in accordance with National Electric
Code Standards as to conductor size and limitations (see NFPA 70, articles 200-
280, as amended, if required), and lightning protection must be provided.
All RF interconnections must be properly shielded to prevent ingression or
egression of potential interfering sources to existing services.
Any damage to this unit caused by improper wiring/interconnections will void any
warranty extended.
All Wegener Communications products are warranted against defective materials and workmanship for
a period of one year after shipment to customer. Wegener Communications' obligation under this

About This Manual
This manual was composed in Microsoft Word 97, and is configured to be used most easily as an
electronic document. It can be printed and used as a hard copy, but some features, such as links,
are not accessible in that mode.
If viewing the electronic version, we recommend you safeguard the original version to avoid the
effects of somehow altering your master copy.
1. Cross-references
Cross-references are internally linked for easy access. If you are viewing the electronic version
of this manual, and see text that is blue and underlined, such as APPENDIX A you can “click”
your mouse on that text and “hyperlink” to that section.
When you are ready to return to the previous section, “click” on the web toolbar “back” arrow
and return. The web toolbar should appear automatically when you use a link, but if it does not
you can invoke it from Toolbars on the View menu.
Because many users will print the manual, we have also included the page numbers for most
links.
2. Table of contents
You can also link from the Table of Contents to any listed page. This also applies to the List of
Tables and List of Illustrations. Just “click” on the page number for any section, table, etc., you
want to move to. Returning to the Table of Contents works just as in Number 1 above.
3. Other Viewing Methods
In the electronic Word version, there are several methods of moving about a document.
“Clicking” Document Map or Online Layout on the View menu will open a window showing the
document outline. This is similar to the Table of Contents, and will allow you to move about the
document by “clicking” on a section number. It has the advantage of not going away when you
move to another section. It also has the disadvantage of taking up screen space when it is open.
Another way to better view the document is to “click” on the “Up arrow” icon on the Web
Toolbar. This will minimize most of the other toolbars, allowing you to use more of the screen
for viewing the manual.
See Section 1.9 (Page 14) for more information on manual feedback.
