SYSTEM OVERVIEW
The Sigma7 telephone is an aeronautical Communications Center handset. The Sigma7 retractor-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 Sigma7 requires 28 VDC to power the printed circuit board.
The Sigma7 can 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 Sigma7 has 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.

BASIC USE
Note
Throughout this section, the bulleted statements (¾)
indicate specific instructions for
performing an action.
The Sigma7 is similar in operation to a standard office or residential telephone handset. Functions
such as initiating calls, answering calls, and disconnecting calls are accomplished using familiar
procedures. The handset also features a special-function key to provide enhanced features such as
flash transfer and access to programming menus.
1. Making a Call
n Remove the handset from the cradle and press the <On> button to place a call.
n Dial the destination telephone number and wait for the call to connect. This button allows the
phone to operate out of the cradle so it can remain on a desk or other convenient location for
easy access.
2. Answering a call
The telephone handset will ring on an inbound call.
n To answer the call, simply remove the handset from the cradle.
n Press the <On> button and the calling party will be on the line.
3. Putting a Call on Hold
n Press the <Flash> button to place a call on hold and mute the audio so no communication is
possible between the handset and the other party.
n To release the hold feature and restore the call, press the <Flash> button again.
4. Adjusting Ear-Piece Volume
The volume-up button (5) and volume-down button (6) located just below the keypad permit
increasing or decreasing the earpiece volume.
n To increase volume, press the 5 key while the telephone is off hook. Maximum amplification is
earpiece level 4 in the LCD display. The audio level only applies to each call and is reset to the
default level (configurable) when the handset is returned to its cradle.

The Sigma

operates much like a standard telephone device. Functions such as initiating calls,
1. On/Answer
The <On> button will permit the user to answer an incoming call or take the phone off-hook to place
a new call. This button allows the phone to operate out of the cradle and allows the user to set the
phone on a desk or other convenient location for easy access.
2. Off
The <Off> button allows the user to terminate a call that has been answered when the handset is
out of its cradle. This button terminates the call and turns off the phone, allowing the phone to be
set down without replacing it in the cradle. Any time the handset is returned to the cradle, any
existing call will be disconnected and the handset hung up.
3, Flash
The <Flash> button provides a momentary line interruption of about one-half second (500 ms). This
in most cases allows the caller to transfer or set up a conference call with others. This, however,
does not terminate the current call; instead, it places the call on hold until the user finishes his
commands to transfer, conference, or repeat the <Flash> signal again.
4. Digits 0–9, *, and #
The digits 0–9, *, and # allow the user to dial Dual-Tone Multi-Frequency (DTMF) digits. This allows
the user to dial a destination number, cabin number, or other destination easily. The phone will
provide a DTMF digit to the line for as long as the caller presses the key on the keypad.

INTRODUCTION
1. General
This section presents instructions for installing the International Communications Group, Inc. (ICG)
Sigma7 handset. It offers special features while replicating the convenience and simplicity of a
conventional telephone.
Note
The material in this document may be updated at any
point. Therefore, before installing the
Sigma7, please check with ICG at www.icg.aero to
determine whether revisions have been issued to all or
parts of this installation manual.
The Sigma7 unit meets all operational and environmental standards for telephonic devices, as
indicated in the section, System Specifications. In case of question regarding these issues, contact
ICG at the following address:
Customer Support
International Communications Group, Inc.
Newport News, VA 23603
Phone: 1-757-947-1030
2. Planning
(A) Preparation
Review industry-established electronic equipment practices to prepare for installing the Sigma7.
Those practices include reviewing the procedures in this manual; carefully choosing the

(C) Cleaning
Stray fingerprints, smudges, wire clippings, metal shavings, or other debris on outside surfaces of
the chassis should be removed upon completion of installation or repair work.
If cleaning is necessary, use only mild soap and limit water amount to avoid letting any moisture
reach the internal components.
Lightly moisten a cloth and lightly swab the exterior surface in need of cleaning.
3. Abbreviations and Acronyms
A convenient reference guide to abbreviations, acronyms, and symbols used in the text can be
found 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 are abbreviated in the text without also being written out.
4. Advisories
WARNING:
Observe standard safety precautions and wear SAFETY
GLASSES AND OTHER proper safety gear to prevent personal
injury during installations.
CAUTION:
TURN OFF POWER BEFORE DISCONNECTING ANY
COMPONENT FROM WIRING. DISCONNECTING THE
COMPONENT WITHOUT TURNING POWER OFF MAY
CAUSE VOLTAGE TRANSIENTS THAT CAN DAMAGE THE
COMPONENT.
CAUTION: ELECTRO-STATIC-SENSITIVE DEVICES ARE SUBJECT TO DAMAGE BY
EXCESSIVE LEVELS OF VOLTAGE AND/OR CURRENT, JUST AS ARE
MORE CONVENTIONAL SEMICONDUCTOR DEVICES. HOWEVER, THE
PRECAUTIONS NORMALLY USED TO PROTECT SEMICONDUCTORS
ARE NOT SUFFICIENT FOR THE PROTECTION OF ELECTRO-SENSITIVE
DEVICES BECAUSE OF THEIR VERY HIGH ELECTRICAL RESISTANCE.
THE LOW-ENERGY SOURCE THAT MOST COMMONLY DESTROYS
THESE DEVICES IS THE HUMAN BODY WHICH, IN CONJUNCTION WITH
NONCONDUCTIVE GARMENTS AND FLOOR COVERINGS, GENERATES
AND RETAINS STATIC ELECTRICITY. TO PROTECT ELECTROSENSITIVE DEVICES ADEQUATELY, THE DEVICE AND EVERYTHING
THAT CONTACTS IT MUST BE BROUGHT TO GROUND POTENTIAL BY
PROVIDING A CONDUCTIVE SURFACE AND DISCHARGE PATHS.

THE FOLLOWING PRECAUTIONS MUST BE FOLLOWED before installing the
SIGMA7:
DE-ENERGIZE OR DISCONNECT ALL POWER AND SIGNAL SOURCES AND
LOADS BEFORE INSTALLING THE SIGMA7.
PLACE THE COMPONENT ON A GROUNDED, CONDUCTIVE SURFACE.
GROUND THE INSTALLER THROUGH A CONDUCTIVE WRIST STRAP OR OTHER
DEVICE USING A 470-KILOHM OR 1-MEGOHM SERIES RESISTOR TO PROTECT
THE EQUIPMENT.
GROUND ANY ELECTRICAL TOOLS, SUCH AS SOLDERING EQUIPMENT THAT
WILL CONTACT THE COMPONENT. CONTACT WITH THE OPERATOR'S HAND
PROVIDES A SUFFICIENT GROUND FOR TOOLS THAT ARE OTHERWISE
ELECTRICALLY ISOLATED.
WHEN ESDS DEVICES AND ASSEMBLIES ARE NOT IN THE COMPONENT, THEY
SHOULD BE ON THE CONDUCTIVE WORK SURFACE OR IN CONDUCTIVE
CONTAINERS. WHEN A DEVICE OR ASSEMBLY IS INSERTED OR REMOVED
FROM A CONTAINER, THE OPERATOR SHOULD MAINTAIN CONTACT WITH THE
CONDUCTIVE PORTION OF THE CONTAINER. DO NOT USE PLASTIC BAGS
UNLESS THEY HAVE BEEN IMPREGNATED WITH A CONDUCTIVE MATERIAL.
DO NOT HANDLE ESDS DEVICES UNNECESSARILY OR REMOVE THEM FROM
THEIR PACKAGES UNTIL ACTUALLY USED OR TESTED.

It can be connected to any CTU or transceiver that emulates a 2-wire or 4-wire subscriber circuit.
The device can be mounted in different ways to accommodate a variety of needs. The Sigma7 has
an LCD display and built-in magnetic stripe reader for all types of calling services.
The Sigma7 handset permits a single mode of operation: On/Answer” mode. This mode permits the
handset to be kept out of the cradle, yet be available to place outbound calls and answer inbound
calls. The handset has two special keys: <On> which is used to take the phone off-hook to place a
call or to answer an inbound call, and <End> which is used to terminate a call and hang up the
telephone. Any time a user replaces the telephone into the cradle, the telephone will hang up or
disconnect the line regardless whether the <End> button was pressed. If the telephone is in the
cradle on an inbound call, the call will not be answered until the user removes the handset and
presses the <On> button to answer the call.
Operation is identical for either the 2-wire or 4-wire model of the Sigma7 cabin handset.

INSTALLATION PROCEDURES
1. Planning
The ICG Sigma7 is easy to install and test. However, both advance planning and review of this
document are recommended before an installation. A regular toolkit is sufficient for attaching all
hardware to the aircraft.
2. Connections
The 2-wire Sigma7 telephone has a Printed Circuit Board (PCB) with three RJ-11 jacks, an 8-Pin
connector, located on the under side of the cradle, and an RJ-11 jack inside the cradle (optional).
The 4-wire Sigma7 is fitted with a cable assembly terminated with a DB-15 male connector. The
RJ-11 jacks in the 2-wire phone and the DB-15 connector in the 4-wire phone are used for all
connections to the handset. The jacks are labeled J1, J2, J3, J4, and J5. Connections are as
follows:
J1 – Telephone Line
J2 – Retractor Reel Handset Connection
J3 – External Ringer Connection
J4 – 8-Pin Header for connection for LAN system
J5 – Currently, RJ-11 for Data Modem Connection.
(A) Line (J1)
This is the connection to the telephone circuit of a CTU system, transceiver, or other telephone
subscriber circuit. The center two pins of the RJ-11 jack (Pins 3 and 4) are the telephone circuit
for the handset. The adjacent two pins (Pins 2 and 5) can be used for a separate connection for
the data jack, if installed.
An RJ-11 jack can have four or six contact pins. In a four-pin RJ-11 jack, the first and last pins
are not installed (pins at each end). However, although the pins may be absent, they are still
counted in the standard numbering scheme. An RJ-11 jack has pins designated 1 through 6.
The center two pins are always Pins 3 and 4 even if Pins 1 and 6 are not installed

(B) Phone (J2)
This is the connection for the retractor-reel connected to the handset. It is typically factory
installed and must remain in its location.
(C) Ringer/Audio (J3)
This RJ-11 jack permits connection for an external ringer device. As with all RJ-11 connections,
the two inner pins (3 and 4) will provide the ring signal on the telephone circuit during an inbound
ring, to be connected to the external ringer device.
International Communications Group, Inc.
User’s Guide and Installation Manual
Sigma7
Aviation Telephone Handset
Note
External ringer devices connected to the Sigma7
external ringer jack should be of a type that ring
upon application of a standard telephone ring signal.
Telephone circuit ring signals are typically 20–25 Hz
at 40–85 VRMS. Reference ICG P/N 938035 for
external ringer.
CAUTION
DO NOT CONNECT EXTERNAL POWER TO THIS
JACK.
3. Wiring
ICG recommends that 22- to 26-AWG stranded wire be used. The cable should be a single or dual
twisted pair cable (if separate data circuit required) with overall shield and drain wire. The drain wire
should be connected to aircraft ground at the CTU or transceiver end and left un-terminated at the
telephone end.
n Terminate the end at the telephone into an RJ-11 plug.
n Ensure that the RJ-11 plug is of the correct type to accommodate the size of wire used and that it
is designed to accept discreet wires and not telephone flat cord.
Note
ICG can provide the correct RJ-11 plugs
if they cannot be obtained locally.

4. Mounting the Handset
The cord-reel mounting methods for installing the Sigma7 device are standard cradle installation,
remote retractor reel, and handset with coil cord. The mounting methods on the cradle are described
as follows:
The Sigma7 cradle is most commonly mounted flush on a convenient surface. The cradle is fastened
with 4 screws into a cut-out in a drink rail drawer or cabinet. The completion center typically selects
the screw size and length required to fasten the cradle. P/N 500088, 6/32 x ¾-inch captive screws
and nuts are included in the cradle assembly. The handset sits in the cradle. See the section, Fits
and Clearances, for a dimensional drawing of the cradle; that drawing should be used to determine
the dimensions of the cutout required to accept the cradle.
Retractor Reel and Handset may need to be fastened into an enclosure without the cradle or with a
short cradle that does not accommodate fastening of the retractor reel. In this case, the handset is
installed or supported in a custom enclosure or lying loose in a cabinet and the retractor reel is
mounted close but not attached to the cradle.
The mounting screws must not protrude more than 10mm into the
cradle cavity, or damage to the handset may result. The screws
should be of a diameter to fit inside of the holes provided to
Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document.

Phone Does Not Ring
n Remove handset from cradle to ensure that the ringer annunciator is
exposed and unobstructed. Ring handset in an extension-to-extension
call.
¾ If another handset is available, plug the J1 plug into the new handset to
verify that a ring signal is arriving at the handset from a CTU or
transceiver system.
Audio Feedback through the Handset
¾ Typically, this problem is evident when the MICVOL, RXL, or TXL are
set too high, which causes too much amplification in the internal audio
circuits. Decrease these adjustments starting with the one set the
highest until comfortable audio is heard and the feedback is not evident.
