Additional Performance Enhancement

The following are some of the latest creations designed to
enhance the security, quality and efficiency of APX mobile
radios.

Dynamic System Resilience (DSR)

DSR ensures the radio system is seamlessly switched to a
backup master site dynamically in case of system failure.
DSR also provides additional indication e.g. failure detection,
fault recovery, and redundancy within the system to address to
the user in need. Mechanisms related to the Integrated Voice
and Data (IV & D) or data centric are all supported by DSR.

ASTRO 25 Enhanced Data

ASTRO 25 Enhanced Data is optimized to handle different
message sizes and variable update rates from different
applications of the radio. Add Enhanced Data to the Integrated
Data system with a software installation to improve data
channel efficiency and enable denser network traffic.

CrossTalk Prevention

This feature prevents crosstalk scenario from happening,
especially when a wideband antenna is used. This feature
allows the adjustment of the Trident Transmitting SSI clock rate
in the radio to be varied from the Receiving Frequency. This
subsequently reduced the possibilities of radio frequency
interfering spurs and prevents the issues of crosstalk.

Encrypted Integrated Data (EID)

EID provides security encryption and authentication of IV & D
data bearer service communication between the radio and the
Customer Enterprise Network.

SecureNet

SecureNet allows user to perform secured communications on
an Analog or Motorola Data Communication (MDC) channel.
The MDC OTAR feature will allow users to perform OTAR
activities on an MDC channel.

P25 Digital Vehicular Repeater System (DVRS)

Motorola Solutions offers an MSI Certified APX compatible, 3rd
Party, P25 Digital Vehicular Repeater System (DVRS) that
provides low cost portable radio coverage in areas where only
mobile radio coverage is available and portable radio coverage
is either intermittent or non-existent.

Monitoring Features

Radio users who switch from analog to digital radios often
assume that the lack of static on a digital channel is an
indication that the radio is not working properly. This is not the
case.

Digital technology quiets the transmission by removing the
“noise” from the signal and allowing only the clear voice or data
information to be heard.

Monitor a channel to ensure the channel is clear before
transmitting.

Monitoring a Channel

Procedure:

Lift the microphone off hook.

Conventional Modes Only:

1 Listen for activity on that channel.

2 Adjust the volume by rotating the MFK if necessary.

3 If you hear no activity, press and hold the PTT button to start

your conversation.

OR

Trunked Modes Only:

1 Press the PTT button.

2 If you hear two, short, high-pitched tones, or if you hear no

tone and the t indicator lights steadily, then proceed with

• Select-enabled radios are free to change to any available
channel, including the dynamic-regrouping channel, once the
user has selected the dynamic-regrouping position.

• Select-disabled radios cannot change channels while
dynamically regrouped. The dispatcher has forced the radio
to remain on the dynamic-regrouping channel.

The Scan or Private Call feature cannot be selected while your
radio is Select Disabled.

Contacts

This feature provides “address-book” capabilities on your radio.
Each entry corresponds to an alias (name) or ID (number) that
you use to initiate a call.

Contact entries are alphabetically sorted according to entry
alias. Each alias can have up to 5 IDs of different call types
associated with it.

Additionally, each entry, depending on context (conventional,
trunking, or phone), associates with one or more of the four
types of calls: Phone Call, Selective Call, Private Call, or Call
Alert.

Each entry within Contacts displays the following information:

• Call Alias (Name)

• Call ID (Number)

conventional, then the encryption keys are strapped to the
talkgroups.

• Trunked Multikey – If you use your radio for both
conventional and trunked applications, you have to strap your
encryption keys for trunking on a per-talkgroup or
announcement-group basis. In addition, you may strap a
different key to other features, such as dynamic regrouping,
failsoft, or emergency talkgroup. You can have operator­selectable key erasure.

Press the PTT button again, or the H or Emergency button,
to exit the feature and transmit in normal mode.

4 If the rekey operation fails, a bad-key tone sounds and the

display shows Rekey fail.

Note: The rekey operation failure indicates that your radio

does not contain the Unique Shadow Key (USK). This
key must be loaded into the radio with the key-variable
loader (KVL) before the rekey request can be sent.

Refer to your local key management supervisor for
more information.

MDC Over-the-Air Rekeying (OTAR) Page

This feature allows to view or define MDC Over-the-Air
Rekeying (OTAR) features.It is applied only when operating in
secure encrypted mode and only for conventional
communications. In additional to Rekey Requests, OTAR
transmissions include Delayed Acknowledgements, and Power­up Acknowledgements.

Some of the options selected may also need to be set up at the
Key Management Controller (KMC) site to work properly.

Note: This feature must be preprogrammed by a qualified

radio technician. Check with your dealer or system
administrator for more information.

Infinite UKEK Retention

This feature enables Unique Key Encryption Key (UKEK) to be
permanently stored in the radio even when all of the encryption
keys is erased. Without this UKEK key, the radio could not be
over the air rekeyed.

Note: This feature must be preprogrammed by a qualified

radio technician. Check with your dealer or system
administrator for more information.

Hear Clear

There are two components of Hear Clear.

1 Companding:

Reduces the channel noise, e.g. OTA transmission, that is
predominantly present in UHF2 and 900 MHz channel with
the following features.

• Compressor – reduces the background noise flow and the

speech signal at transmitting radio.

• Expander – expands the speech while the noise flow

remains the same at receiving radio.

2 Random FM Noise Canceller (Flutter Fighter):

Reduces the unwanted effects of random FM noise pulses
caused by channel fading under high Signal-to-Noise (S/N)
conditions such as in a moving in a transportation. The fading
effects, heard as audio pops and clicks, are cancelled without
affecting the desired audio signal.

The Random FM Noise Canceller operates only in receive
mode.

Note: This feature must be preprogrammed by a qualified

radio technician. Check with your dealer or system
administrator for more information.

The Global Positioning System (GPS)

This feature uses information from the Global Positioning
System (GPS) satellites orbiting the Earth to determine the
approximate geographical location of your radio, expressed as
latitude and longitude. The availability and accuracy of this
location information (and the amount of time that it takes to
calculate it) varies depending on the environment in which you
are using the GPS feature.

For example, GPS location fixes are very difficult to obtain
indoors, in covered locations, between high buildings, or in
situations where you have not established a clear broad view of
the sky.

Understanding the GPS Feature

The GPS technology uses radio signals from earth orbiting
satellites, to establish the location co-ordinates, maximizing
your view of clear unobstructed sky is essential for optimum
performance.

Where adequate signals from multiple satellites are not
available (usually because you cannot establish a view of a
wide area of the sky), the GPS feature of your radio will not
work. Such situations include but are not limited to:

• In underground locations

• Inside of buildings, trains, or other covered vehicles





Advanced Features

82

• Under any other metal or concrete roof or structure

• Between tall buildings or under dense tree-cover

• In temperature extremes outside the operating limits of your
radio

Even where location information can be calculated in such
situations, it may take longer to do so, and your location
estimate may not be as accurate. Therefore, in any emergency
situation, always report your location to your dispatcher.

Note: Even where adequate signals from multiple satellites

are available, your GPS feature only provides an
approximate location, usually within 20 meters from
your actual location, but sometimes further away.

Keep in mind that the accuracy of the location information and
the time it takes to obtain it varies depending upon
circumstances, particularly the ability to receive signals from an
adequate number of satellites.

Note: The satellites used by the GPS feature are controlled

by the U.S. government and are subject to changes
implemented in accordance with the Department of
Defense GPS user policy and the Federal Radio
Navigation Plan. These changes may affect the
performance of the GPS feature on your radio.

Enhancing GPS Performance

Sometimes, the GPS feature may be unable to complete a
location calculation successfully. You then see a message
indicating that your radio cannot connect to enough visible
satellites.

To maximize the ability of your radio to determine a fix, please
note the following guidelines:

• For your initial fix, hold the radio in the face position.

• Stay in the open. The GPS feature works best where there is
nothing between your radio and a large amount of open sky.

The Outdoor Location Feature (Using GPS)

This feature allows you to determine your current location using
a location menu, as well as your current distance and bearing in
relation to another location. Radio location may be requested
and reported over-the-air.

Your radio stores up to a maximum of sixty (60) programmable
location coordinates, also known as waypoints. When the
memory is full, the next waypoints automatically replaces the
oldest waypoints in the radio.
