2 Introduction
This manual provides users with instructions on the operation of the Flightcell DZMx and, if installed, the
Flightcell DZMx Remote Head and cabin phone.
Overview of DZMx Functions
The Flightcell DZMx is a powerful communications system that uses the Iridium satellite and/or 3G cellular
networks to provide:
2.1.1 Voice calling
The DZMx provides a global phone service, enabling calls to virtually any phone in the world
The DZMx is interfaced to the aircraft audio system, providing all crew connected to the audio system
with access to the available phone networks
A cabin phone may also be installed for passengers’ use
Calls are dialled from the DZMx keypad, or by using the phone directory or speed dial keys to retrieve
and call stored phone numbers
Other parties can call the aircraft by dialling the aircraft’s satellite or cell phone numbers.
2.1.2 Two-way messaging
SMS text messages can be sent to the DZMx over either the satellite or cellular network, from any
SMS-capable phone (a cell phone or another satellite phone)
SMS messages can also be sent to the DZMx over the Iridium network from an Iridium web
application or any email program
Messages from the DZMx’s message library can be sent either to another satellite phone or cell phone,
or to your tracking service provider.
2.1.3 Aircraft tracking
The DZMx can send periodic position reports automatically and manually triggered position reports to one of
a number of tracking service providers. Additionally, the DZMx can be configured to send position reports
that mark specific events, including:
Start-up
Engine start and stop
Take-off and landing
Course change
Manual position
Emergency (mayday)
Other special purpose events.
In addition to GPS flight tracking, the DZM also has Automated Rescue Monitoring (ARM, also known as
Automated Flight Following, AFF) capabilities. Used in conjunction with an appropriately configured receiving
server and a compatible computer mapping system, ARM provides automatic surveillance over an aircraft or
vehicle's mission. While activated, ARM monitors position reports and automatically raises alerts if no
position data has been received from the aircraft for a specified time period (set on the receiving server). This
ARM feature is only available with some mapping systems, for example TracWatch, Automated Monitoring
Service by TracPlus. Please contact your mapping service provider about availability of the ARM/AFF service
on their network and to register for this service.

DZMx Hardware Configurations
The DZMx can be supplied in different hardware configurations to suit the type of aircraft and the operator’s
requirements. A range of software applications provide additional functionality for specific types of
operations. The features available on the DZMx will depend on the hardware and software configuration.
2.2.1 Transceivers
The DZMx has a modular design which allows installation of different transceivers, enabling use of the Iridium
satellite and/or cellular phone networks.
Any one or two of the following transceivers can be installed in the DZMx’s internal transceiver slots:
A Flightcell Iridium transceiver card
A Flightcell cellular transceiver card.
The following external transceiver options may also be installed:
A Flightcell Iridium module
A Flightcell cellular module
An Iridium phone in a Flightcell Iridium phone cradle; cradles are available for the Iridium 9505/A,
9555 and Extreme handsets.
2.2.2 Remote access configurations
The DZMx is usually installed in the pilot’s panel or pedestal, where it can be operated only by the pilot(s).
The DZMx may also be connected to additional equipment to enable other crew members to make and receive
calls and messages:
A Flightcell DZMx Remote Head; installation of one or more remote heads allows crew or passengers
in the cabin to access all the functions of the DZMx
A cabin phone; installation of a cordless or corded phone allows passengers to make and receive calls
without needing a headset. The cabin phone can also be used with the DZMx to provide an intercom
between cockpit and cabin.

3 Using the DZMx
The DZMx keypad is designed to provide the most common functions via the least number of key presses.
Within one or two key presses, the DZMx can initiate phone calls, answer calls, access the phone book, mark a
position, toggle Automated Rescue Monitoring, send text messages, view received messages and activate
emergency mode.
Other less commonly used functions are available via the menu system, which also provides for configuration
of the DZMx.
If a DZMx Remote Head is fitted, either the DZMx or the remote head can be used to carry out all available
keypad functions, and all screens will show the same information.
The DZMx keypad
The keys on the DZMx 16-key keypad are used for dialling calls, sending
messages and accessing a number of other functions.
The DZMx keys have different functions depending on what screen is
currently being displayed, and whether the DZMx is in a call or not.
Due to the limited number of keys, and the many functions available,
some keys on the keypad have more than one function. For example,
pressing a key can have a different function to pressing and holding a
key.
The following describes the functions of the different keys. The “Key Name” lists the names used in the text
when referring to this key.

For systems fitted with three transceivers, two transceivers will be shown beside a soft key, for example, a
system with two satellite devices will show the status of the two devices on the main screen next to soft key A.
When making a call or sending a message, the DZMx will always check if the internal device is available first,
then, if it is busy, disabled for voice calls and/or messages, or has no good signal, the DZMx will then check if
the external device is available. If a transceiver has no signal, or has not been configured for a particular
operation, when the user attempts an operation, they will be informed via a pop-up that the transceiver is
offline or the operation is unavailable.

Flightcell DZMx Users’ Guide Page 13 of 31
Understanding the information on the DZMx Display
During normal operation, the DZMx LCD display shows the Main
Screen.This displays:
On the top line, current GPS position
In the centre of the display, transceiver information:
Transceivers installed in each position in the DZMx
Status of each of the installed transceivers; this changes
depending on the operation currently being performed
Signal strength (up to four bars); if the phone doesn’t
have a connection, it shows
Above the transceiver information, additional information on:
Messaging activity, including number of queued messages
Phone number or name of the other party to an active
phone call
On the bottom line
Tracking status; if the DZMx is not tracking, it shows the
reason
A.R.M status (if A.R.M. is activated).
4.1.1 Transceiver connection status
The transceiver status message will change as the DZMx establishes a connection to the network:
Powering Up is displayed when the DZMx is waiting to connect to the or satellite or cellular
transceiver
Initialising is displayed when the DZMx has established a connection to the transceiver and is in
the process of initialising the device
Ready is displayed when the transceiver is powered on, has been successfully initialised by the
DZM, is registered on the network and is reporting a good signal strength, but it is not in use
No Signal is displayed when the transceiver is not registered on a network and has no signal.
This can happen during a flight as the aircraft passes in and out of coverage. The device cannot be
used for calls or messaging
Low Signal is displayed when signal strength is low. A low signal may cause the DZMx to use the
alternative device for tracking if configured to do so. The device is still available for incoming and
outgoing calls, but be aware it is possible that the call may be dropped due the poor connection.
The display will show an error message if the DZMx can’t be connected for some reason:
No Device is displayed when there is either no external satellite phone in the phone cradle or the
external phone or modem is powered off. If after a minute or two the DZMx has not established a
connection with the device, the DZMx will display a warning screen and beep advising that the
device is not responding and alerting the pilot to check it is in the cradle/connected
No SIM is displayed if there is no SIM card in the connected transceiver. This is also displayed if
the SIM is present, but is unregistered. If the SIM is locked, blocked or requires a PIN, the DZMx
will notify the user of the appropriate status
Incorrect SIM is displayed if the DZMx detects a SIM but it does not have the correct service
centre number, which would normally indicate that the incorrect SIM has been inserted.
4.1.2 Device status during a call
While you are making a phone call, the transceiver status lines will show you which device is currently being
used for the call, and on the line above, who you are calling, or being called by. If the other party is listed in
the DZMx’s phone book, then the information line will display their name.
The phone or modem status message changes as the DZMx establishes a connection with the other party:
Calling... is displayed when the DZMx has dialled the number but a connection has not yet been
established
On Call is displayed when the DZMx has established a connection and the other party has
accepted the call

Incoming Call will flash on the DZMx display, an audible ringing tone will sound over the audio
system and the call annunciator light (if installed) will flash if there is an incoming call
Disconnecting is displayed when a phone call is terminated at either end of the call or the phone
or modem loses the connection.
4.1.3 Messaging activity
The transceiver status lines will briefly show information on transmission of tracking messages:
Sending Data... when an SMS or SBD message is being transmitted
SMS failed! or SBD Failed! if transmission has failed, usually because of a low signal; in this case
the DZMx will attempt to resend the message
SMS Sent or SBD sent when an SMS or SBD message has been successfully transmitted.
The line above will also show the number of untransmitted messages in the message queue.
4.1.4 Tracking Status
The tracking status line on the bottom of the display will show aircraft and tracking status:
Tracking: Queuing is displayed if there are more than two messages in the message queue. This
indicates poor cellular and/or Iridium signal strength or that position reports are not being sent
or are being sent at a slower rate than they are being queued
Tracking: Queue Full! is displayed if messages have not been transmitted for quite some time
due to poor signal strength and now the queue is full. Any new position reports will be added to
the queued and the oldest one removed from the queue

4.1.5 Automated Rescue Monitoring (A.R.M.) status
Automated Rescue Monitoring status information is displayed on tracking status line when A.R.M. is
active. Enabling and disabling A.R.M. mode causes the DZMx to send an activate or deactivate message to
the tracking server followed by the DZMx receiving an acknowledgement. The status of this process is
displayed on the status line:
A.R.M. – Requesting is displayed when A.R.M. mode is activated by the user and indicates that
confirmation of A.R.M. operation has been requested from the tracking server
A.R.M. – Active is displayed when the tracking server has responded and confirmed that A.R.M. is active;
the current aircraft status is shown appended to this message: …: On Ground, …: Takeoff, …: In Flight or
…: Landed
A.R.M. – Cancelling is displayed when A.R.M. mode has been disabled by the user and a termination
acknowledgement has been requested from the tracking server
A.R.M. – Terminated is displayed briefly when the tracking server has responded confirming A.R.M. has
been deactivated
No Response. Retry? is displayed when A.R.M. mode activation or termination confirmation has not been
received from the tracking server after several attempts; press ENTER to keep re-trying
No AFF Server Response! Is displayed to advise that confirmation of A.R.M. activation or deactivation
has not been received. No further automated attempts are made.
4.1.6 Emergency mode
When in Distress (Emergency) mode has been activated by the user, Emergency Mode! will flash in the
tracking display line to indicate emergency messages are being transmitted to the tracking provider at
programmed intervals.

6 Making phone calls
The DZMx can be configured with up to two internal transceivers, and one external transceiver. These may be
Iridium and/or cellular transceivers. The available networks and current signal strength are shown on the
main screen.
Calls can be made to virtually any phone number in the world over the Iridium satellite or cellular networks.
Calls may be made from the DZMx or an installed remote head, or from a cabin phone (if installed).
Numbers can be dialled manually or recalled from the 50-number phone book. The DZMx also has three speed
dial keys that call the first three numbers in the phone book.
You can also initiate a call from a received text message if the caller’s number is shown with the message.
The DZMx supports caller ID on the Iridium network and on most cellular networks.

Answering calls from the DZMx or remote head
When the DZMx detects an incoming call, and the pilot is not already in a call, an Incoming call pop-up will
flash on the DZMx. If caller ID is supported by the network, the caller’s phone number, or name, if the number
matches any in the phone book, will also be displayed. A ringing tone will be produced over the audio system
and a call annunciator light (if installed) will flash. If a cabin phone is connected, and is not already in a call,
this will also ring.
Press CALL to answer an incoming call,or press END to reject the call
Press END to hang up.

Other functions during a call
6.3.1 Using touch tone dialling (DTMF) during a call
When calling through a switchboard or call centre, you may be asked to press a number or the star (*) or
hash/pound (#) key. This is called touch-tone or DTMF dialling.
The DZMx provides touch tone dialling when in a call. Simply press the 0 to 9 or * or # keys when prompted
during a call.
6.3.2 Using other DZMx keypad functions when on a call
To use the MARK,A.R.M.,EMER,MSG, or MENU keys during a call, press and hold the applicable key for 1.5
seconds to override DTMF dialling on that key.
6.3.3 Adjusting DZMx audio levels
Only the level of audio from the DZMx to the ICS (ear volume) can be adjusted by the user. An installer will
have access more audio settings, such as keypad beep volume, mic volume, warning tone volume etc, within
the menu system and via the DZMx Manager utility.
Once these are set up correctly, the pilot will only need to adjust the ear volume occasionally to allow for
differing incoming audio levels, or to adjust for different headsets or for ambient noise conditions.
To adjust incoming audio level:
Go to MENU>Audio>ICS>Ear; the DZMx will display the setting
Use LEFT or RIGHT to adjust the audio level
Press ENTER to confirm the setting change and return the the audio menu
Press BACK to abort the change and return to the audio menu.

7 Making phone calls using the DZMx cabin phone
A corded or cordless phone may be installed in the cabin and connected to the DZMx to provide passengers
with access to the DZMx Iridium sat phone and/or cell phone connections.
Calls are private to the connected party (cockpit or cabin) unless a three-way call is established.
If the DZMx has two transceivers (e.g. one Iridium and one cellular, or two Iridium), the cockpit and cabin may
each use a transceiver to make simultaneous calls.
The cabin phone can also be used with the DZMx as an intercom between cockpit and cabin.
If the cabin phone is in use, the call status is shown on the bottom line of the DZMx display.
The dialling method is similar to that on the DZMx keypad in that a transceiver must be selected first before
dialling the phone number.
To make an internal call between the cabin phone and the pilot, or to transfer a call to the pilot, requires the
use of either the ‘hook/flash’ or ‘flash’ key, or optionally programing of one of the speed-dial buttons on the
cabin handset to ‘701#’. The best method used will depend on your handset type.
Dialling a phone number
Pick up the handset and press the off hook button and wait until you hear the dial tone
Select the desired transceiver by pressing either 1 for transceiver Aor 2 for transceiver B
Dial the phone number
Press # after dialling your number to initiate the call immediately, or wait a few seconds for the DZMx
to recognise no further numbers will be entered, after which it will initiate the call automatically.
Hang up to end the call
If the transceiver selected is already in a call, then the passenger will hear an engaged tone. If the
transceiver selected has no signal, is unavailable (not fitted or not in cradle), or the other party has
hung up, then the passenger will hear a busy tone. In either case, they will need to hang up and try
again later, or try again using another transceiver.
Initiating an intercom call between the cabin and pilot
Pick up the handset and press the off hook button and wait until you hear the dial tone
Press ‘hook flash’, or the appropriate speed-dial key to initiate a call to the pilot. If the pilot is already
busy on a call, then the passenger will hear an engaged tone. If the pilot is available, then a ring tone
will be generated on the ICS until the pilot answers or until either party hangs up the call.
The call will be terminated if either the cabin phone goes on hook, or the pilot presses END
If the pilot hangs up, the passenger will hear the busy tone through the handset
Transferring a call from the cabin phone to the pilot
If the cabin phone is on a call using one of the transceivers, and the pilot is not busy on another call, it is
possible to transfer the call to the pilot. During a call, the cabin phone can invite the pilot into a three-way call
to initiate the call transfer, or once connected, maintain a three-way call between the cabin phone, transceiver
and the pilot.
While on a call, the cabin phone can invite the pilot into the call by pressing ‘hook flash’ or the
appropriate speed-dial key. If the pilot is available, then a ring tone will be generated on the ICS until
the pilot answers or the pilot can reject the invite by pressing END.
Once the pilot has answered, a three-way call is established. The cabin phone party can choose to
hang up at that point, or continue to have a three-way conversation.
Once a three-way call is established, if either the pilot or the cabin phone hang up, the call will turn
into a standard two-party call between the remaining parties. If the party at the transceiver end
hangs-up, the call is terminated.

7.3.1 Transferring a call from the pilot to the cabin phone
If the pilot is on a call using one of the transceivers, and the cabin phone is not busy on another call, it is
possible to transfer the call to the cabin-phone.
While on a call, the pilot can invite the cabin phone into the call by pressing the CALL key. If the cabin
phone is available, then the handset will ring until the cabin phone answers the call.
Once the passenger has answered, a three-way call is established. The pilot can choose to hang up at
that point, or continue to have a three-way conversation.
