Foreword
1. About This Manual
This manual presents the instructions for using and installing the Sigma7telephone handset on
aircraft. For convenience and ease of use, this document is divided into two major sections.
General information is in the User’s Guide that follows the front matter; that information targets the
casual user or cabin personnel. Detailed installation instructions can be found in the Installation
Manual section; that information is geared to installation personnel.
A convenient reference guide to abbreviations, acronyms, and symbols used in the text is in the
Glossary at the back of this document. Specialized terms will generally be written out everywhere in
the text to avoid confusion. Standard, well-known electronic terms and circuit signal names will be
abbreviated in the text without being defined. Also, a fairly comprehensive International Country
Code Directory is at the back of this manual.
Customer Support at ICG welcomes your questions, comments, and corrections about this manual.
In any correspondence, we would appreciate the publication number, equipment designations
(found on the Sigma7handset), document page or figure number, and your comments. Please send
your communication to the following address:

2. The Sigma7Handset
The Sigma7telephone is an aeronautical Communications Center handset designed to operate as a
standard and familiar telephone. The Sigma7is similar in operation to an office or residential
telephone. The device accommodates various mounting methods and has features similar to those
found on contemporary telephones. Facilities such as a Liquid Crystal Display (LCD) and built-in
magnetic stripe reader provide convenient operation and support for all types of calling services.
The handset also facilitates data port connectivity for modem or Ethernet as an optional
configuration.

SYSTEM OVERVIEW
The Sigma7telephone is an aeronautical Communications Center handset. The Sigma7retractor-reel
handset is similar to current aeronautical handsets in appearance and form factor but is much simpler and
more conventional in its use. Both the 2-wire and 4-wire handsets have uncomplicated menus and
functions that are easy to learn or understand. The 2-wire version requires no external power other than
a telephone circuit connection; the 4-wire Sigma7requires 28 VDC to power the printed circuit board.
The Sigma7can be recessed into a drink rail or bulkhead. ICG offers an optional data jack (RJ-11) option
located in the cradle. The data jack can be either paralleled with the telephone circuit or it can be
connected to a separate circuit so that both telephone and data calls can be active at any time.
The Sigma7has an internal magnetic stripe reader to support credit card calls and a special-function key
to provide enhanced features such as flash transfer and access to programming menus.
