1.3 OPERATING TIPS

Antenna location and condition are important when operating a portable radio. Operating the radio in low
lying areas or terrain, under power lines or bridges, inside of a vehicle or in a metal framed building can
severely reduce the range of the unit. Mountains can also reduce the range of the unit.

In areas where transmission or reception is poor, some improvement may be obtained by ensuring that the
antenna is vertical. Moving a few yards in another direction or moving to a higher elevation may also
improve communications. Vehicular operation can be aided with the use of an externally mounted
antenna.

Battery condition is another important factor in the trouble free operation of a portable radio. Always
properly charge the batteries.

1.3.1 Effi cient Radio Operation

Keep the antenna in a vertical position when receiving or transmitting a message.
Do not hold the antenna when receiving a message and, especially, do not hold when transmitting a

message.

Do NOT hold onto the antenna when the radio is powered on!

1.3.2 Antenna Car e and Replacement

Do NOT use the portable radio with a damaged or missing antenna. A minor burn

damaged antenna immediately. Operating a portable radio with the antenna missing
could cause personal injury, damage the radio, and may violate FCC regulations.

La radio portative Harris XG-75P produit de l’énergie électromagn étique des RF
lorsqu’
« Utilisation professionnelle seulement », ce qui signifie qu’elle ne doit être utilisée
que dans le cadre d’
moyens de limiter ceux-ci. Cette radio N’EST PAS conçue pour une utilisation par
la « Population générale » dans un environnement non contrôlé.

La radio portative XG-75P a été testée et est con forme aux limites d’exposition aux RF de la FCC pour
une « Utilisation professionnelle seulement ». De plus, cette radio Harris est conforme aux normes et
directives suivantes quant à l’énergie des RF et aux niveaux d’énergie électromagnétique, ainsi qu’à
l’évaluation de ces niveaux pour l’exposition aux humains :

• Bulletin 65 du OET de la FCC, édition 97-01, supplément C, portant sur l’évaluation de la conformité

aux directives de la FCC quant à l’exposition humaine aux champs électromagnétiques des
radiofréquences.

• American National Standards Institute (C95.1 – 1992), norme de l’IEEE sur les niveaux sécuri taires

d’exposition humaine aux champs électromagnétiques des radiofréquences, 3 kHz à 300 GHz.

14221-1100-2010, Rev. G

AVERTISSEMENT

2.2.1 Direct i ves sur l’exposition aux RF

Pour s’assurer que l’exposition à l’énergie électromagnétique des RF se situe dans les
limites acceptables de la FCC pour l’utilisation p rofessionnelle, respectez toujours les
directives suivantes :

• N’utilisez PAS la radio sans qu’une antenne appropriée y soit connectée, car ceci peut endommager la

radio et également causer un dépassement des l imites d’exposition aux RF de la FCC. Une antenne
appropriée est celle fournie par Harris avec cette rad io, ou une antenne spécifiquement autorisée par
Harris pour être utilisée avec cette radio. (Reportez-vous à Table 7-1.)

• Ne transmettez PAS pendant plus de 50 % de la durée d’utilisation totale de la radio (« cycle de

service de 50 % »). La transmission pendant plus de 50 % du temps peut causer un dépassement des
exigences de conformité de la FCC en matière d’exposition aux RF. La radio transmet lorsque
l’indicateur « TX » apparaît sur l’affichage. La radi o trans met lorsqu ’on appuie sur le bouton « PTT »
(bouton de microphone).

• Transmettez TOUJOURS en basse puissance lorsque possible. En plus de préserver la charge de la

pile, une faible puissance réduit l’exposition aux RF.

• Utilisez TOUJOURS des accessoires autorisés Harris (antennes, piles, pinces de ceinture, haut-

parleurs/micros, etc.). L’utilisation d’accessoires non autorisés peut entraîner un dépassement des
exigences de conformité pour une exposition aux RF professionnelle ou contrôlée de la FCC.
(Reportez-vous à Tableau 2-1.)

• Tel qu’indiqué dans Tableau 2-1, conservez TOUJOURS l’appareil et son antenne à AU MOINS

1,6 cm (0,63 po) du corps, et à au moins 2,5 cm (1,0 po) du visage pendant la transmission, pour vous
assurer de ne pas dépasser les exigen ces de conformité de la FCC en matière d’exposition aux RF.
Cependant, pour offrir la meilleure qualité sonore aux auditeurs de votre transmission, Harris
recommande de tenir le microphon e à au moins 5 cm (2 po) de votre bouche et légèrement déplacé
sur un côté.

2.4 CONSEILS D’UTILISATION

L’emplacement et l’état de l’antenne sont importants pour l’utilisation d’une radio portative. L’utilisation
de la radio dans des zones de faible élév ation, sous des lignes électriques o u des ponts, à l’intérieur d’un
véhicule ou dans un immeuble à ossature métallique, peut réduire la portée de l’appareil de manière
considérable. Les montagnes peuvent également réduire la portée de l’unité.

Dans les zones où la transmission ou la récep tion est insatisfaisante, certaine s améliorations peuvent être
obtenues en s’assurant que l’antenne est verticale. Se déplacer de quelques mètres dans une autre
direction ou à un emplacement plus élevé peut également améliorer les communications. L’utilisation
d’une antenne fixée à l’extérieur peut faciliter le fonctionnement dans un véhicule.

L’état de la pile est un autre facteur important d’une utili sation sans tracas d’une radio portative. Chargez
toujours correctement la pile.

2.4.1 Util isation Efficace de la Radio

Gardez l’antenne dans une position verticale pendant la réception ou la transmission d’un message.

CAUTION

5. BATTERIES

The XG-75P series portable radios use rechargeab le, recyclable Nickel Metal Hy dride (NiMH), Lithium­Ion (Li-Ion), or Lithium Polymer (Li-Poly) batteries. Please read the battery information provided
carefully to maximize the useful life of each type of battery.

Do not disassemble or modify Lithium batte ry packs. Lithium battery packs are
equipped with built­disabled or tampered with in any way, the battery pack can leak electrolyte,
overheat, emit smoke, burst, and/or ignite.

If the battery is ruptured or is leaking electrolyte that results in skin or eye contact
with the electrolyte, immediately flush the affected area with water. If the battery
electrolyte gets in the eyes, flush with water for 15 minutes and consult a physician
immediately.

5.1 CONDITIONING BATTERY PACKS

5.1.1 Conditi oning NiMH Battery Packs

Condition a new NiMH battery before putti ng into use. This also applies to rechargeable NiMH batteries
that have been stored for long periods (weeks, months, or longer). Conditioning requires fully charging
and fully discharging the battery three (3) times using the tri-chemistry charger. The first time the battery
is put into the charger, this unit will condition Nickel-based battery packs by automatically charging and
discharging (cycling) the battery. Refer to the appropriate charger manual for details.

shortened performance by the battery.

5.1.2 Conditioning Li-Ion or Li-Poly packs

Lithium battery packs do not suffer from memory effect and do not require conditioning.

5.2 STORING LI-ION BATTERY PACKS

If a battery pack is expected to be idle fo r a month or more, i t should be properly prepared. Li-Ion battery
packs should not be stored fully charged. Before storing the battery pack, discharge it to 40% capacity. If
the battery is not discharged prior to storage, its overall capacity may be reduced. Although all battery
packs experience some capacity loss during storage, the shelf life for Li-Ion battery packs is about 3
months. However, note that any capacity drop which occurs during storage is permanent and cannot be
reversed. Li-Ion battery packs should be purchased and used immediately. They should not be stock­piled without a rotating stock plan.

26

14221-1100-2010, Rev. G

5.3 CHARGING BATTERY PACKS

Battery chargers are available fro m Harris with nominal charge times. Combinations i nclude single and
multi-position charge units.

Harris chargers are specifically designed for charging nickel-based and lithium battery packs. The
chargers are chemistry-specific for the battery packs and automatically adjust the charging profiles
accordingly. Refer to the appropriat e charger manual for specific operating instructions.

Observe the following guidelines when charging a battery pack:

• Avoid high temperature during charging.

• Discontinue use if the charger is overheating.

• Only charge Harris battery packs using a charger approved for use by Harris.

• Do not leave batteries in the charger indefinitely. For best result s, leave the battery in the charger for

two to six hours after the Green Ready LED comes on. Then place the battery pack into service and
fully discharge (as indicated by the radio lo w battery warning) before re-charging.

If any faults are encountered while charging the battery pack, con sult the charger’s manual to deter mine
the cause and possible corrective action.

5.4 BATTERY PACK USAGE

NiMH, Lithium-ion, and Lithium Polymer batteries vary in capacity and life cycle. NiMH, Lithium-Ion,
and Lithium Polymer batteries require that basic usage guidelines be followed in order to optimize the
battery runtime or shift life.

The following guidelines will help optimize the battery runtime or shift life:

• Ensure Nickel-based battery packs are fully discharged (as indicated by the radio low battery

warning) before re-charging. Full discharge is not required for Lithium battery packs.

• Periodically condition Nickel-based battery packs. The frequency should be determined based on

usage patterns (refer to ECR-7367). If the battery is fully discharged (to radio Low Battery warning)
during routine use, the frequency of conditioning may be reduced. Lithium-ion and Lithium Polymer
batteries do not suffer from memory-effect and therefore do not require conditioning.

Do not leave any Harris rechargeable bat teries in a charger for more than a few days.

6. INTRODUCTION

The XG-75P is available in two models: the Scan model with a limited 6-button front-mounted keypad
and the System model with a 15-button DTMF front-mounted keypad. The Harris XG-75P portable radio
delivers end-to-end encrypted digital voice and IP data communications. It is designed to support
multiple operating modes including:

• EDACS

• P25 Trunked Mode

• P25 Digital Conventio nal Mode

• OpenSky

• Conventional Analog Mode

The XG-75P portables can include all of these modes or just one. Additional modes of operation can be
added with software updates.

The XG-75P supports a full range of advanced digital trunking features, including talk group calls,
priority scanning, emergency calls, late call entry, and dynamic reconfigu ration. It performs autonomous
roaming for wide area applications. High quality voice coding and robust audio components assure
speech clarity.

®

(Enhanced Digital Access Communications System) or ProVoice™ Trunked Modes

®

Trunked Protocol (700/800 MHz radio only)

In the trunked modes, the user selects a communicati ons “operating” system (i.e., EDACS, ProVo ice, or
P25) and group. While communicating in a trunked mode, channel selection is transparent to the user and
is controlled via digital communication with the system controller (e.g., a CSD in an EDACS system).
This provides advanced programmable features and fast access to communication channels.

In Conventional Analog mode, the user selects a ch annel and communicates directly on that channel. A
channel is a transmit/receive radio frequency pair.

The exact operation of the radio will depend on the operating mode, the radio’s programming, and the
particular radio system. Most features described in this manual can be enabled through programming.
Consult your System Administrator for the particular features programmed into your XG-75P. Then refer
to the corresponding section(s) within this manual for feature and operation information.

The XG-75P series portable radios operate reliably even under adverse conditions. These radios meet
MIL-STD-810G specifications for wind driven rain, humidity, and salt fog.

9.2 TRI-COLOR LED

Figure 9-6: Tri-Color LED

The Tri-Color LED changes color to indicate radio status and is visible from both the front and top of the
radio (see Figure 9-6).

In OpenSky mode the following radio states are reflected by the LED and the status they represent are:

Green: Receiving
Red: Transmitting
Orange: If the LED is flashing rapidly, the radio is receiving an emergency call. If the

LED is flashing every ½ second, the selected Talk Group is in the emergency
state (although not transmitting). If the selected Talk Group is in the emergency
state, an asterisk will be displayed next to t he Talk Group name.

9.3 LOG-IN TO THE NETWORK

Log-in occurs either automatic ally (auto registration) if the radio has a valid registration or, if enabled,
requires the user to enter a User ID and password.

The user will be prompted with “Pls Login” if one Talk Group in the selected profile
can be encrypted. The user has to log-in to use that Talk Group in encrypted mode.

1. Press *1 keys (Log-in command).

2. Enter the full 10-digit User ID.

3. Press the key.

4. Enter the password.

5. Press the key.
The User ID may be remembered from the previous log-in. (Refer to Section 9.4 for further details

regarding log-off commands.) The password will be established before the radio is put into operation.
Contact the local OpenSky network administrator for more information.

38

If necessary, contact radio system admi nistration personnel for log-in assistance and/or
radio-specific log-in instructions.

9.4 LOG OFF THE NETWORK

The *0## command de-registers the radio. Typically, this is automatically performed when powering
down the radio. Using this method, the User ID is remember ed by the radio, so only the password is
needed at next log-in. If a user is logged in, it is necessary to log-off.

9.5 PERSONALITY

As illustrated in Figure 9-7, a personality defines the profiles and Talk Groups available to the user. It is
the structuring of a collection of profiles and privileges established by the OpenSky network administrator
to provide the user with a comprehensiv e set of profiles to communicate effectively with the necessary
Talk Groups or individuals.

Personalities are stored on the network and downloaded over-the-air to the radio. This process is called
“provisioning.” Provisioning occurs at radio power-up (if the personality is not already stored in the
radio’s memory) and at user log-in (if the radio has been deregistered). When changes are made to the
personality, the radio is automatically re-provisioned. Each personality can contain up to 16 profiles and
each profile can contain up to sixteen Talk Groups.

9.5.1 Profiles

As stated above, each profile can contain up to 16 Talk Groups. A profile also defines the radio’s
emergency behavior. All transmissions are made on the sel ected Talk Group (displayed on the top line of
the dwell display). The user can change the sel ected Talk Group to any of the other Talk Groups within
the profile.

Figure 9-7: Personality Structure Example

9.5.2 Talk Gr oups

A Talk Group represents a set of user s that regularly need to communicate wit h one another. There can
be any number of authorized users assigned to a Talk Group. Talk groups are established and organized
by the OpenSky network administrator. An OpenSky Talk Group is similar to a channel within a
conventional FM radio system.

The second line will display information su ch as activ e menu, log-in prompt, emergency status, and dwell
display messages as described in the following section.

9.6.3 Dwell Display

When not engaged in menu selection, the first two lines of the display default to the user-defined display,
known as the “dwell display.” The to p line indicates the curren tly selected Talk Group. The second line
will display the currently selected profile, caller ID/alias
if the channel menu is enabled. Press the button repeatedly to scroll through and view one of these
second line options.

Selection knob on top of the radio or use the Talk Group selection menu.

9.17 ADJUSTING DISPLAY AND BUTTON BACKLIGHT BRIGHTNESS

1. Press the or buttons until Bright Menu is displayed.

2. Use or to brighten or dim the display and button backlighting.

9.18 STEALTH MODE

For some users, it is important to be able to turn off the radio’s display lights and side tones, but not the
radio traffic. For example, in covert operations, lights and sounds could inadvertently expose an
otherwise unobservable radio user. For this purpose, the radio has a Stealth feature that disables the radio
display lights, indicator lights, audible alert, and side tones.

48

When Stealth Mode is on, the radio continues to scan the programmed list of Talk Groups and the user
can key-up on the selected Talk Group.

9.18.1 Enabling Stealth Mode

System Model only: Quick Key combination 2# toggles Stealth Mode on and off.
Both models: Press the or buttons to scroll through menus until “StealthMenu” appears in the

display. To immediately activate Stealth Mode press the or button once. This activates Stealth
Mode, exits the Stealth Menu, and returns to the Dwell Display.

The display lights, indicator lights, and side tones are disabled. The stealth mode icon is displayed.

9.18.2 Disabling Stealth Mode

System Model only: To re-enable all lighting, side tones and exit Stealth Mode, press Quick Key
combination 2# again. The radio returns to the Dwel l Display.

NOTE

NOTE

Stealth Mode can also be disabled by using the Stealth Menu.

Scan Model only: To re-enable all lighting, side tones, and exit Stealth Mode, press any k ey other than
PTT or Emergency. The radio returns to the Dwell Display.

The display lights, indicator lights, and side tones are re-enabled. The stealth mode icon disappears.

9.19 ADJUSTING SIDE TONE AUDIO LEVEL

The radio sounds confirming tones called “side tones” when its buttons are pressed. Most user s find this
audible confirmation helpful when navigating the menus. Side tone audio level can be adjusted or turned
completely off using the “Side Menu” or the Quick Key combination #4.

Quick Key combination 4# turns off the backlight in addition to the side tones. Unlike
Stealth Mode, alert tones can still be heard .

For covert operations, it may be necessary to turn off side tones. For safety’s sake, turning off the radio
during covert operations is not recommended.

If the radio is operating properly but side tones are not heard when the menu buttons are pressed, the side
tones are probably turned off. To turn them back on, acces s the “Side Tone” menu and select a setting
other than “off.”

Use the following procedure set side tone lev el:

1. Press the or

buttons to cycle through the menu until “Side Menu” is displayed.

2. Press or to change to the desired level (Off, Low, Medium, and High). To turn side tones off
completely, use the “Off” setting.

9.21 RECEIVI NG AND TRANSMITTING VOICE CALLS

As soon as the radio completes the initializatio n sequence an d registers o n the Open Sky network , the user
will begin to hear calls from the Talk Groups in the active profile, if available.

9.21.1 Receiving a Voice Call

No action is required to receive a voice call. The display responds to incoming voice calls as foll ows:

• When the dwell display is set to received Talk Group and the scan mode is Normal or Fi xed:

a. If the received Talk Group matches the selected Talk Gro up, then the alias (if available) or user

ID of the incoming caller is displayed.

b. If the received Talk Group does not match the selected Talk Group, then the received Tal k Group

name is displayed.

• When the dwell display is set to received Talk Group and the Scan Mode is None, the radio only
receives voice on its selected Talk Group. When the call is r eceiv ed , t he ali as ( if avail abl e) or t h e u ser
ID of the incoming caller is displayed.

• When the dwell display is not set to received Talk Group, then there is no display indication of an
incoming call.

A radio receiving a System All Call, Regency All Call, or an Agency All Call displays
“All Call” instead of the alias. A radio not transmitting on a Talk Group in emergency
status will drop all other calls to scan into an All Call.

9.21.2 Transmitting a Voice Call

1. Select the desired Talk Group.

2. Depress and hold the PTT button, wait a couple of seconds. If programmed by the administrator, a
grant tone will be sounded.

3. Begin speaking into the microphone in a normal voice.

4. For maximum clarity, hold the radio approximately 2 inches from your mouth. Take care not to cover
up the microphone while speaking.

5. Release the PTT button to terminate an outgoing voice call.

9.23 TALK GROUP L OCK OUT

There are two ways to focus voice communic ations by suppressing calls from Talk Groups in the active
profile.

• No Scan. By changing the Scanning Mode to “No Scan” only the selected Talk Group is scanned.

• Lock Out. By locking out selected Talk Groups, background noise or chatter can be eliminated, and

scanning resources can be focused on just those groups whose calls you wish to monitor.

Lock out is a listening (receive) function and only blocks received calls on locked out
Talk Groups. Lock out does not affect transmit capability. “No Scan” and “Lock Out” do
not apply to recent emergency lock outs.

Only Talk Groups in the active profile can be locked out, since they are the only Talk Groups whose
voice calls can be heard on the radio. Talk group lock out is a scan-related feature. With lock out, one or
more Talk Groups in the active profile can be temporarily disab led from being scanned. Calls are not
received on locked-out Talk Groups. Lock out settings are not retained between profile changes.

P1, P2, and P3 groups CANNOT be locked out.

The default emergency and emergency-capable Talk Groups can be locked out if they are NOT in an
emergency state. If a Talk Group is locked out and is subsequently changed to the currently selected Talk
Group, it will automatically be unlocked by the radio so the user can hear calls on the Talk Group. The
radio may be configured so all Talk Groups are automatically locked out by default. In this case, they
must be manually unlocked, if desired.

9.23.1 Lock Out a Talk Group

1. Use the or buttons to scroll through the menu choices until “LockOutMenu” appears in the
display.

2. Use the or keys to scroll through the list of Talk Groups, if any, until the user group you want to
lock out appears in the display.

3. Press the key to select the lo ckable Talk Group.

4. “<” appears next to the locked out Talk Group.

9.23.2 Unlock a Talk Group

1. Use the or buttons to scroll through the menu choices until “LockOutMenu” appears in the
display.

2. Use the or keys to scroll through the list of Talk Groups, if any, until the user group you want to
unlock appears in the display.

3. Use the key to unlock the displayed Talk Group.

• Changing the active profile removes any lockouts you have made.

• Turning off the radio removes any lockouts you have made.

9.24 SCANNING

9.24.1 Selecting Scan Modes

Three scanning modes are available for the radio, but only one can be active at any time. Changing the
scanning mode changes the way the radi o scans voice calls for all of the profiles in the radio personality,
no matter which profile is or becomes active.

The choice of scanning mode broadens or narrows the span of communications with all the groups in
profiles you listen to, but does not affect your interaction with those groups you talk with. The scanning
modes available for selection may be limited by the administrator to a subset of the three scanning modes.

Receive calls from more than one Talk Group, if available from the current site.
Allows dragging of the selected Talk Group, P1, P2, P3, and emergency Talk Group (in emergency state) to

the site on which the radio is registered. (If other calls are available at the site, they also can be heard but they
will not be actively dragged.)

The default emergency Talk Group, as well as any emergency-enabled Talk Groups, is only dragged if it is in
emergency mode.

Functions the same as Normal Scan Mode, except the priority groups are fixed to the selected profile’s pre­defined P1 and P2 groups (configured via the UAS).

EXPLANATION

The scanning mode choice remains in effect until it is changed. Even if the radio is turned off, the current

9.25 MAKING SE LECTI VE CA LL S

Selective calling is the capability for two voice radio units to obtain and use an independent talk path for a
unit-to-unit call. A properly equipped radio can initiate a selective call to any radio in the system that is
also programmed for selective calls.

In the OpenSky system, a radio can be co nfigu red to in itiate selective calls through a pre-programmed list
in memory called a speed dial list. Alternatively, a properly equipped radio can initiate a selective call to
any radio in the system by enterin g the ten-digit User ID (similar to a telephone number) of the target
radio. Some radios are configured to only receive (not initiate) selective calls.

Selective calls are terminated if an emergency is declared. The network limits selective
calls to ten (10) minutes maximum.

If a Selective Call is attempted without registration, “No Priv” is displayed.

9.25.1 Manually Dialing a Selective Call (System Model Only)

1. Enter *8, the User ID number of the user being called, and the # key (no dashes or spaces). This
feature must be enabled by the administrator.

*8<destination user id>#
A shortened User ID number can be dialed using the following guidelines:

• If the radio being called is in the same region and agency – enter only the last four digits.

• If the radio being called is in the same region, but a different agency – enter only the last seven

digits.

• If the radio being called is in another region or if the area is unknown – enter all ten digits.

2. Press the PTT (and release) to ring the o ther user.
The ring tone is sounded.
If the other user accepts the call, the called user’s alias will appea r in initiating caller’s display. The

two are now in a unit-to-unit call until one ends the call, the call is terminated due to an initiated
emergency, or the maximum time limit of ten ( 10) minutes is reached.

If the called radio is busy, “BUSY” will appear in the second line of the display.

9.26 SELECTIVE ALER TS

Selective alert messaging is an OTP feat ure that allows one of up to eight (8) pre-programmed (canned)
text messages to be sent from one radio to another. The sender speci fies a destination (receiving) radio,
selects one of the pre-programmed text messages, and then transmits it to the destination radio. The
message delivery system adds sender and time-of-day information and forwards the message to the
destination (receiving) radio. The sending radio receives a brief message noting the status of the
transmission.

Received messages are stored in th e radio until deleted or until the rad io is rebooted. Received messag es
do not survive a reboot.

9.26.1 Defining Messages

All selective alert messages are pre-defined. The messages are programmed and provisioned remotely by
your OpenSky system administrator. Th e radio user cannot create selective alert message content. The
entire selective alert message, including the abbreviation, can be up to 99 characters long .

9.29 OPENSKY ENCRYPTION

In the OpenSky network, both data and voice use a 128-bit or 256-bit key encryption standard published
by the Federal Information Processing Service (FIPS), called Advanced Encryption Standard (AES).
AES is approved by the U.S. Department of Commerce for encryption of classified materials.

When encryption is enabled on the network, data is encrypted from the MDIS to the Mobile End System
(MES) (e.g., XG-75P portable radio). This form of encryption provides airlink security.

Voice encryption is handled either automatically or manually. Automatic encryption is initiated through
the Unified Administration Server (UAS) for a specific Talk Group and requires nothing from the radio
user. Manual encryption is initiated by two or more radio users. Both methods of encryption are
discussed in the following sections.

When a user transmits encrypted voice, any listening users with different encryption keys
hear distorted voice and “No Access” appears in the radio display.

9.29.1 Automatic Encryption

For automatic encryption, a system administrator will select the Talk Group to be encrypted at the
interface to the UAS. Once the Talk Groups have been selected and id entified as secure, credentials for
key generation are generated automatically by the system and provisioned to authorized users. This
process requires that authorized users log-in to the network and be authenticated. Encryption keys require
no manual handling and are never sent “in t he clear” over any network interface or airlink.

1. Locate the Talk Group that has been encrypted at the system administrat or level.

2. “Pls Login” appears in the display (unless the keypad was used to log-in).

3. Log-in normally by entering your User ID and Password.

If a user is engaged in a call on a Talk Group encrypted at the net work administ rator level, “Secu re Call”
will appear in the second line of the dwell display if the user is logged into that Talk Group.

If a secure call is in progress elsewhere and the user has not logged in, the bottom of the dwell display
will alternate between “No Access” and the alias of the radio that is currently engaged in the secure call.

9.29.2 A/B Switch

If configured, the A/B switch can be used to enable or disable encryption.

9.29.3 Manual Encryption (System Model Only)

Two or more users can manually encrypt a call, if enabled, witho ut an established encry pted Talk Group.
A pre-determined “key or code” is req uired. While a user is eng aged in a manually encrypted call, users
within the Talk Group that are not encrypted can still make standard voice calls on th at Talk Group. The
encrypted user can hear the standard unencrypted calls, but cannot respond while still manually
encrypted.

Manual key entry only affects the curren tly selected Talk Group. All available Talk Groups within the
current profile may be independently encrypted.

The key must be pre-determined by the users prior to making a manually encrypted call on
a Talk Group and is entered into the radio using the keypad. For 128 bit encryption, this
key is between 1 and 16 digits. For 256 bit encryption, this key is between 17 and 32
digits.

9.29.3.1 Using Manual Encryption

1. Press *32 on the keypad.

2. Enter the key (1 – 16 digits for 128 bit encryption; 17 – 32 digits for 256 bit encryption).

3. Press #.

4. To end manual encryption, press *33.
If a user is engaged in a call o n a Talk Group th at has been manually en crypted at the rad io lev el, t he user

If a secure (encrypted) call is in progress, and the user has not entered the key, the bottom of the dwell

display will alternate between “No Access” and the alias of the radio that is currently engaged in the
secure call.

Once the user has terminated manual e ncryption, “UnSecure” appears temporarily in the bottom line of
the dwell display.

9.34 V-TAC OPERA TION

9.34.1 Extended Coverage Modes (XCOV, XCOV-TG, and XCOV-PROF)

In addition to all standard portable radio operating capabilities, Extended Coverage adds the V-TAC’s
bridging (vehicular repeat) function ality for accessing the OpenSky radio network. Each portable radio
connected to the V-TAC using Extended Coverage is considered a “client” on the V-TAC. Extended
Coverage benefits portable radio users since it allows them to get network connectivity using the
V-TAC’s higher transmit output power and better antenna system.

The V-TAC supports three Extended Coverage modes: Extended Coverage for individual users (XCOV),
Extended Coverage for a Talk Group (XCOV-TG), and Profile Extended Coverage (XCOV-PROF).
Typically, Extended Coverage is used a fter the vehicle’s operator has exited the vehicle with a p ortable
radio unit and the portable unit requires this bridging functionality to access the OpenSky radio network.

The V-TAC takes advantage of OpenSky’s T DMA capability to eliminate interference between its lo cal
and network radio links when operating in an Extended Coverage mode, an undesirable characteristic of
many traditional vehicular repeater sy stems. Because the V-TAC employs this technology, interference
on the network and local radio links is minimized.

A V-TAC in Extended Coverage mode sends its alias to cli ents. The alias is displayed in the second line
of the dwell menu of the client, (“VA <alias>”). The client must be connected to a V-TAC running

63

14221-1100-2010, Rev. G

version OTP14.4 or later for the V-TAC to provide the alias to the client. If the client is connected to a V­TAC running version OTP14.3.1 or earlier, the client displays “VA None.”

9.34.2 Change Between Extended Coverage Modes

By default, the specific Extended Coverage mode utilized is determined by settings programmed into the
V-TAC and portable radios from the system administrator or radio installation personnel. These
programmed settings determine which Extended Coverage mode the V-TAC and radios normally use and
determine the access method employed by a portable radio to connect to the V-TAC. After these settings
are programmed to the V-TAC and portable radios, each must be rebooted (powered off and then back
on) before the change takes effect.

See the following sections for instructions on how to override this setting manually. The override is only
successful if the V-TAC operating mode matches the manually selected portable V-TAC mode.

9.34.3 Radio Limitations Using Extended Coverage Modes

Connecting a portable radio to a V-TAC introduces minor functional limitations. See the following
sections for a listing.

9.34.3.1 Limitations Using XCOV, XCOV-TG, and XCOV-PROF

Portable radios connected to the V-TAC u sin g any of the Ex ten ded Coverag e Mo des, XCO V, XCOV-TG,
or XCOV-PROF, will not channel-scan unless they lose radio frequency contact with the V-TAC. If
manually enabled, radios will not scan netwo r k channels.

9.34.3.2 Limitations Using XCOV-TG

The following portable radio keypad functions are disabled when the radio is connected to the V-TAC
using the XCOV-TG mode: log-off, manual log-in, alerts, selective calls, PSTN calls, and speed dial
calls, SOI mode, RTT.

The following portable radio menus are disabled when the radio is connected to the V-TAC using the
XCOV-TG mode: alert destination, alert message, alert received, channel, speed dial, priority 1 Talk
Group, priority 2 Talk Group, priority 3 Talk Group, RTT, Status message, site lock and scan mode. In
addition, the user cannot change Talk Group or profile.

9.34.3.3 Limitations Using XCOV-PROF

The following portable radio keypad functions are disabled when the radio is connected to the V-TAC
using the XCOV-PROF mode: log-off, manual log-in, alerts, selective calls, PSTN calls, and speed dial
calls, SOI mode, RTT.

The following portable radio menus are disabled when the radio is connected to the V-TAC using the
XCOV-TG mode: alert destination, alert message, alert received, priority 1 Talk Group, priority 2 Talk
Group, priority 3 Talk Group and scan mode. In addition, the user cannot change Talk Group or profile.

9.34.4 Use XCOV Mode

The Extended Coverage for individual users (XCOV) mode allows up to eight (8) client radios to connect
to the V-TAC. The radios have full radio functionality including selective calling and mobile data.

64

With the Extended Coverage for individual users’ (XCOV) mode, V-TAC configur ation defines which
portable radios are permitted V-TAC access. The radio will automatically connect to a V-TAC if it
cannot find a network channel. The radio can also be manually connected to a V-TAC as indicated with
the *61# and *62# commands, each determined by the system administrator in the radio configuration.

14221-1100-2010, Rev. G

9.34.4.1 Manually Accessing the XCOV Mode

System Model Radios

1. Press *61# to manually access XCOV mode.

2. Press *60# to manually disconnect from XCOV mode.

Both Model Radios

1. Press or until the Client Mode menu appears.

2. Press or until XCOV is displayed.

3. Press to confirm mode selection. The radio reverts to the dwell display and the V-TAC icon is
displayed.

9.34.5 Use XCOV-TG Mode

When using the XCOV-TG mode, up to thirty (30) client radios can connect to the V-TAC. However,
unlike XCOV, radios connected using XCOV-TG are limited to communicating only on the XCO V-TG
Talk Group. The radio can only raise an emergency if this Talk Group is emergency capable. Advanced
features such as selective callin g and mobile data operations are not available to the XCOV-TG connected
clients. The radio will automatically connect to a V-TAC if it cannot find a network channel.

The Talk Group used for XCOV-TG communications is the Talk Grou p that was selected at the V-TAC
when it entered XCOV-TG mode. Befo re a radio can connect to the V-TAC, the Talk Group must be
selected on the radio. If this Talk Group is not provisioned in the radio’s personality, the radio cannot
connect to the V-TAC via the XCOV-TG mode. While connected to the V-TAC via XCOV-TG, a
different Talk Group or profile cannot be selected.

When a portable radio is connected to the V-TAC via XCOV-TG, the V-TAC forwards only the network
voice traffic on the XCOV-TG Talk Groups.

9.34.5.1 Manually Accessing the XCOV-TG Mode

For the Extended Coverage for a Talk Group mode (XCOV-TG), a portable radio user is granted access
and connects to the V-TAC by simply selecting the same Talk Group that the V-TAC had selected wh en
it entered the XCOV-TG mode. Contact the system administrator for questions regarding these aspects.

During XCOV-TG mode operations, the V-TAC will not disconnect portable radios connected to it. A
portable radio user must manually disconn ect from the V-TAC by pressing *60 # on the radio’s keypad.

However, if the V-TAC is switched out of the XCOV-TG mode, all portable radios will be automatically
disconnected from the V-TAC. The radios will continue to look for another V-TAC until manually
disconnected (*60#).

System Model Radios

• Press *62# to manually access XCOV-TG mode.

• Press *60# to manually disconnect XCOV-TG mode.

Both Model Radios

1. Press or until the Client Mode menu appears.

2. Press or until XCOV-TG is displayed.

3. Press to confirm mode selection. The radio reverts to the dwell display and the V-TAC icon is
displayed.

65

14221-1100-2010, Rev. G

CAUTION

9.34.6 Using XCOV-PROF Mode

In XCOV-PROF mode, client attachment to a V-TAC is based on profile rather than Talk Group.
XCOV-PROF mode allows the transmission an d receip t of voice ca lls on any Talk Group in the profile as
opposed to only one Talk Group. XCOV-PROF allows emergencies on a non-selected Talk Group based
on the emergency behaviors of the profile. XCOV-PROF minimizes data traffic between the client and V­TAC while allowing flex ibility of voice fun ctionality. As a resul t, data services between the client and V­TAC are disabled. The radio will automatically connect to a V-TAC if it cannot find a network channel.

Note the following regarding XCOV-PROF mode:

• The client profile must match the V-TAC.

• The client profile used to connect to the V-TAC must have been previously provisioned to the client

prior to connection. If the profile is not in the client’s personality, the client cannot connect to the V­TAC.

• Neither th e V-TAC nor a client can change the profile once it has entered XCOV-PROF mode. The
Profile menu will be disabled.

• Client global profiles are disabled.

9.34.6.1 Access XCOV-PROF Mode

System Model Radios Only:

• Enter the command *63# to set the radio to use the XCOV-PROF mode.

• Press *60# to disconnect from the XCOV-PROF mode.

9.34.7 Use Scene-of-Incident Mode

The Scene-of-Incident mode (SOI) is user-selectable. Th e SOI mode provides a local repeater function
(V-TAC) with no network connection.

When operating in the SOI mode, the radio is disconnected from the OpenSky network.
Therefore, communications with radios and dispatch personnel on the network is not
possible.

10.5 UNIVERSAL DEVICE CONNECTOR

The Universal Device Connector (UDC) provides co nnections for external accessories such as a head set,
a speaker-microphone, audio test box, audio test cables, and programming cables. The UDC is located on
the right side of the radio, opposite the PTT Button. The UDC facilitates programming and testing the
radio. The UDC pins perform different functions depending on the accessory attached to the UDC.

Figure 10-7: XG-75P 15-Pin Universal Device Connector

10.6 NOISE CANCELLATION

The XG-75P features Harris’ proprietary noise suppression capability to provide clear and crisp voice
quality in high-noise environments for use in any mode, including both analog and digital
communications.

The XG-75P has two microphones; one located on the front (primary) and one on the rear (secondary).
The primary microphone operates in exactly the same manner as a nor mal radio and is the one you talk
into. The secondary microphone is used to pick up the surrounding noise when noise cancellation is
turned on.

In the case where noise cancellation is enabled and a speaker microphone is att ached to the XG-75P, talk
into the speaker microphone. In this mode, XG-75P front microphone is used to pick up the surrounding
noise, and the rear microphone is unused.

If the secondary microphone is blocked, the XG-75P operates as though noise cancellation is turned off.

10.6.1 Turning Noise Cancellation On and Off

A button on the radio or the A/B switch can be programmed to toggle noise cancellation on or off.

OR

1. Press the button.

2. Use the or button to select “NOIS CAN.”

3. Press the again to toggle noise cancellation on or off.
The top line of the display will briefly display “NC ON” or “NC OFF.” When noise cancellation is

enabled, the icon is displayed on the bottom of the display.

73

14221-1100-2010, Rev. G

10.6.2 Using Noise Cancellation

When using the noise cancellation feature, observe the following:

• Talk within two (2) inches of primary microphone (see Figure 10-8).

• Speak clearly, loudly, and with authority.

• If possible, face the noise source when talking into the radio (see Figure 10-8).

• Ensure the primary and secondary microphones are not covered. See Section 10.6.4 for more

information on the primary and secondary microphones.

• In very noisy environments, it is okay to yell into the radio. The radio can handle very loud input
levels.

Figure 10-8: Using the Noise Cancellation Feature

10.6.3 The Effect of Distance from the Microphone

Unlike a normal microphone system, noise cancellation makes the level of your voice diminish quickly as
you move away from the radio. In essence, the radio starts to see your voice as surrounding noise.
Whereas, you may be comfortable speakin g up to a foot away from the front of a normal radio, noise
cancellation requires that you keep it close.

10.6.4 Primary versus Secondary Microphone

10.6.4.1 Without a Speaker Microphone Attached

The primary microphone is located on the front of the radio and the secondary is on the back of the radio.

10.6.4.2 With a Speaker Microphone Attached

When a speaker microphone is attached, the radio electronically switches over to use the radio’s front
microphone as secondary. The microphone on the attached speaker microphone becomes the primary
microphone.

10.22.1 Wide Area System Scanning

The XG-75P series radio c an be p re-programmed through RPM for Wide Area System Scan operation for
roaming across mobile systems. ED ACS radio systems manage the radios assi gned to the system via a
control channel (CC). Upon the loss of the currently selected system's control channel, radios can be
programmed to automatically scan the control channels of other systems. If a new control channel is
found, the radio will switch to the new system and sound an alert tone. The amount of time before the
radio enters Control Channel Scan after losing the control channel is configurable in RPM.

10.22.2 Priority System Scan

The radio can also be pre-programmed for Priority System Scan. The priority syst em is the desired or
preferred system. While receiving the control channel of the sele cted system, the radio will peri odically
leave the selected system and search for the cont rol channel of the priority system. This is done at a pre­programmed rate defined by th e valu e in th e Pri orit y Scan Ti me control, unless the ProScan
enabled, as explained in the following sections. This priority scan timer is reset each time the PTT button
is pressed or when the call is received. If the priority system control channel is found, or meets the
predefined criteria (ProScan), the radio will automatically switch to the priority system.

10.22.2.1 Enabling the Wide Area System Scan Function

If the radio cannot find the control channel o f the selected system and begins to wide area system scan,
the radio will only scan for the priority system control channel if the priority sy stem is in the wide area
scan list.

10.22.2.2 When ProScan is Enabled

The radio monitors the priority system and will switch to the priority system if the pre-programmed
criteria ProScan options are met. If ProScan is enabled, the rate at which the radio will scan for the
priority system is defined by the Sy stem S ample Time control, set in RPM (refer to RPM On-Line Help).
See Section 10.22.3 for more information on ProScan.

10.22.3 ProScan

The radio may be programmed for ProScan system scan operation for multi-site applications. ProScan is
a multi-site, system-scanning algorithm. ProScan provides the radio with the ability to select a new
system for the radio to communicate on, when the selected system drops below a predefined lev el. This

87

14221-1100-2010, Rev. G

algorithm enables each radio to analyze the signal quality of its current control channel and compare it
with the signal quality of the control channel for each site in its adjacent scan list. The signal quality
metric used for the ProScan algorithm is based on a combination of both Received Signal Strength
Indicator (RSSI) and Control Channel Verification (CCV) measurements. When the selected system
degrades to a pre-programmed level, the radio will begin to look for a better control channel. Once a
control channel that exceeds the pre-programmed parameters is found, the radio will change to the new
system and emit a tone (if enabled through programming). If the control channel is completely lost, the
radio will enter Wide Area System scan ning and search the prog rammed adjace nt systems un til a suitabl e
control channel is found.

10.23 EMERGENCY OPERATION

The radio's ability to declare an emergency , clear an emergency, remain locke d on an emergency system
and group, and the emergency audio and display freeze can each be enabled or disabled through
programming. When an emergency is declared, scanning will stop and restarts only after the emerg ency
has been cleared.

10.23.1 Receiving an Emergency Call

When receiving an Emergency Call on the sel ected group and system, an alert beep is heard and is
displayed. The message *RXEMER* flashes in the display on line two until the emergency condition is
cleared.

10.23.2 Declaring an Emergency Call

Perform the following steps to send an emergency call to a selected system and group (or on an optionally
pre-programmed group).

1. Press and hold the red EMERGENCY button that is on top of the radio in front of the antenna for
approximately one second (this time is programmable and therefore could be longer or shorter; check

10.27 INDIVIDUAL CALLS

10.27.1 Receiving and Responding to an Individual Call

When the radio receives an individual call (a call directed only to the user's radio), it un-mutes on the
assigned working channel and display s . The first line on the display shows the logical ID number of

the unit sending the message, or the associated name if the ID number is found in the individual call list.
The radio can be programmed to ring when an individual call is received. If enabled, the ring begins five
seconds after the caller un-keys and will continue until the PTT button, the button, or the individual
call mode is entered.

The volume of the ring is adjustable through the volume control levels.

If a response is made by pressing the PTT to the call prior to the programmed call-b ack time-out, the call
will automatically be directed to th e originating unit. If a response is not made before the cal l-back time­out, the radio will return to normal receive display, and *WHC* will appear on the first line of the LCD.

To respond after the call-back time-out, press the key. The radio's display will show the callers ID on
the first line and WHCI=1 on the second line. Pressing the PTT button at this point will initiate an
individual call back to the original caller.

The radio stores the IDs of the last 10 callers in the Calls Receiv ed List as shown. Individual calls are
stored in the top half of the list (1-10) and Group calls are stored in the bottom half of the list (1-10). The
most recent call is stored in position 1, the second most recent call is stored in position 2, etc.

Figure 10-14: Calls Received Lists

To access the Calls Received List, press the key twice. Use the or

buttons to scroll through

the list. Pressing the key will d isplay the time elapsed since the call was received. After pressing

the display will appear similar to Figure 10-15.

10.28.3 Dual-Tone Multi-Frequency: Overdial

Once the radio has established a connection to th e public telephone system, it may be necessary to “ov er­dial” more digits to access banking services, answering machines, credit card calls, or other types of
systems that require Dual-Tone Multi-Frequency (DTMF) access digits.

Overdial operation can also be used to initiate a telepho ne interconnect call via DTMF sig naling if a dial
tone has already been accessed on the sy stem. This method makes a telephone interconnect call while
operating in the conventional mode but will also function in trunked mode if a dial tone is directly
accessible.

Telephone numbers and other number sequences for overdialing can be stored in the phone list when
programming the radio. These numbers are accessed by pressing the key, then following the
selection mode rules. Perform the following procedures to access and dial these stored numbers.

DATA OFF

Appears on top line of display when the radio is in the data disabled state.

DATA ON

Appears for two seconds on top line of display when the radio is toggled to the data
enabled state.

10.31 DYNAMIC REGROUP OPERATION (EDACS)

Dynamic Regroup Operation permits multiple Talk Groups (up to eight) to be added to a radio via the
system manager. The radio must be pre-programmed to respond to regrouping. Dynamic regrouping will
not be activated in a radio u ntil the sy stem manager sends an activat ion messa ge. Each r adio that receive s
and acknowledges the regrouping instructions is successfully regrouped.

Pressing and holding the button for 2.5 seconds toggles the user into and out of the dynamic regroup
groupset. A double beep will sound for entry or exit. The display will indicate REGRP_0x where "x" is a
digit of 1 to 8 indicating the group (when dynamic regroup has been enabled by the user). If the radio is in
dynamic regroup and the user selects a group that has not been regrouped, the display will show NO

ENTRY. The radio will be prevented from transmitting and receiving calls in this condition except for

scanned groups.
After the time-out expires or th e key has been pressed, th e status is sel ected and is transmitted to the

site or stored in radio memory where it can be polled by the site at a future time.
If the pre-programmed groupset on the curren tly selected system contains an EMER/HOME group and

the radio is in dynamic regroup, the radio will declare the emergency on the currently selected dynamic
group.

10.32 MACRO KEY OPERATION

Macro key operation permits the user to accomplish a series of keystrokes with a single "macro"
keystroke. Each macro key is capable of executing up to twenty (20) keystrokes, to any push button input
(i.e., keypad keys, option buttons, etc.) . Each macro key can be pre-pro grammed to activ ate when pressed
or when released. A macro key can also be pre-programmed to change the key stroke sequence the next
time the macro key is activated.

For detailed operation and assignment of macro keys, contact your communications supervisor or
administrator.

10.33 DATA COMMUNICATIONS

The XG-75P series portable radi os permit both voice and data calls to be transmitted and received. The
radio can handle only one type of call at a time; howe ver, either data or v oice is selected transparen tly by
the operator through normal usage of the radio.

The radios can be connected to a Mobile Data Terminal (MDT) or to a host computer. Any RS-232
compatible device that supports the Radio Dat a Interface (RDI ) protoco l (Version 1.9 1 or greater) may b e
connected to the radio. Support for MDTs or host computers is a programmable option per radio.
Additionally, radios may also be programmed for data only operation (no voice calls transmitted or
received).

10.33.1 Displays

The following will be displayed during data operation:

96

14221-1100-2010, Rev. G

10.33.2 Data Off Operation

The radio can be placed in the data disab led state by any of the followin g methods. When the d ata state is
disabled, DATA OFF appears on the top line of the display.

• Declaring an emergency (no t to be used unless an actual emergenc y condition exists) . Alert tone will

sound.

• Pressing button (if pre-programmed as “no data” key). Alert tone will sound.

• Pressing t he pre-programmed “no data” key. Refer to previous bullet.

10.33.3 Data On Operation

The data state is enabled by one of the following (dep ending on how it was disabled). DATA ON will
appear on the top line in the display for two seconds; then the display will return to normal.

• Pressing t he pre-programmed “no data” (ND) key toggles data state on or off.

• Clearing an emergency. This is valid only if the emergency caused “DATA OFF” operation.

10.33.4 Exiting Data Calls

Under normal conditions, the radio enters the scan lockout mode and returns to the control channel after
completion of a data call (transmit or receive). If, during a data call, one of the following operations
occurs, the data call is immediately terminated and the radio performs the desired function:

• If the PTT is activated.

• If an Emergency is declared by pressing the pre-programmed emergency button.

• If a group or system is changed.

10.33.5 Scan Lockout Mode

Following the transmission or reception of a data call, if scan is enabled, scanning will stop temporari ly.
There are two independent pre-programmed times associated with this mode; one after a received data
call and one after a transmitted data call. During this time, the scan indicator will flash to indicate that
scan is enabled but temporarily suspended. This condition typically returns to normal scan operation
when the pre-programmed time expires; however, the following operations and conditions will terminate
the scan lockout mode before the timeout has expired.

• Pressing the button.

• Pressing the PTT.

• Changing a group or system.

• Entering Telephone Interconnect mode.

• Entering Individual call mode.

• Receiving a new emergency assignment.

• Declaring or cl ear an emergency.

• Receiving an individual or phone call.

• Receiving an Agency, Fleet, or System All Call.

• Pressing (Scan model) or (System model) to toggle Scan on or off.

97

14221-1100-2010, Rev. G

10.33.6 Data Lockout Mode

During the voice call scan hang time (pre-pr ogrammed) the radio does not receive data calls.

10.34 SELECTIVE SIGNALING (CONVENTIONAL)

Selective signaling controls the muting and unmuting of the receive audio. This allows a user or
dispatcher to selectively call an individual radio or group of radios. The XG-75P portable radios support
selective signaling in Type 99 decode format.

10.34.1 Type 99 Operation

Type 99 is a conventional in-band, two-tone sequential signaling method. This conventional signaling
protocol controls the muting and unmuting of a radio. Type 99 encoded base stations, mobiles, or
portables can selectively call individual units or groups of units in a conventional system. Type 99 is
used in paging operations providing a dispatcher with the ability to selectively call a radio or a group of
radios. If Type 99 is enabled in the radio personality, the radio can decode Individual, Group, and
Supergroup Type 99 calls.

In a selective signaling environment, the XG-75P portable radios operate in one of two states, Monitor
mode or Selective Call mode.

• In Monitor mode, Type 99 “OFF,” the decoder is disabled and all calls are heard by the user.

• In Selectiv e Call mode, Typ e 99 “ON,” t he deco der is enab led and only calls in tended fo r the user are

heard.

10.34.2 Type 99 with or without Channel Guard

Selective signaling operates with or witho ut Channel Guard. If Channel Guard is enabled, the radio can
be programmed with an "And" or an "Or" option, determined by programming with T99 Mute Control.

• If the "And" option is programmed, T99 calls require the correct selective signaling (T99 tone

sequence) AND the correct Channel Guard to nes are heard by the user.

• If the "Or" option is programmed, calls with the correct Channel Guard tones OR calls with the

correct T99 tone sequence and Channel Guard tones are heard by the user.

A radio operating in Selective Call mo de th at rec eiv es a sel ecti ve ca ll swit che s to t he Mo n ito r mode (after
decoding the T99 call) and the TX/RX LED flashes green. The TX/RX LED indicates whether the
channel has a carrier signal.

10.34.3 Resetting Type 99 after a Call

After decoding a Type 99 call, the radio operates in Monitor mode and all traffic on the channel is
audible. If the channel has Channel Guard, only the traffic with the radio's Channel Guard tone will be
heard.

To reset Type 99 operation, use one of the following methods:

• Press the button.

98

• Press the button, if enabled through programming to toggle Type 99 on/off.

• Allow the "Auto-Reset" timer, if enabled through programming, to reset the Type 99 decoder.

14221-1100-2010, Rev. G

NOTE

10.34.4 Type 99 Disable after PTT

The radio may be programmed with the Type 99 Disable after PTT feature, which automatically disables
the Type 99 decoder after a transmission.

Use one of the methods outlined in the Section 10.34.3 to reset Type 99 operation.

10.35 AUDIO PLAYBACK

Every call received by the radio is recorded in internal memory, ov erwriting the last recorded cal l. When
the PLAYBACK key is pressed, the last recording is replayed and any future recordings are stopped.
Pressing PLAYBACK again repeat s the same recorded call. Pressing and ho lding the PLAYBACK key
until the tone sounds erases the recording and starts the recording of incoming calls again. If a call is
received while the recorded call i s playing, the recorded call continues to p lay, rather than the received
audio. However, if a call is received and th e recorded call is played back in close succession received
audio could mute call playback. This feature requires RPM R8A and later, and ECP R15A and later.

The PLAYBACK function must be programmed to a button on the radio via RPM.

10.36 RADIO TEXTLINK OPERATION

10.38 CONTROL AND STATUS SERVICES

The XG-75P supports Control and Status services. These services allow the computer application to
monitor and control a radio. The Control and Status Services can be used from a locally-connected
Mobile Data Terminal (MDT) or a network MDT. In some cases, the radio can support both MDTs
simultaneously. However, priority is given to the local MDT.

The Radio Status Service allows an MDT or Fixed End System (FES) to receive real-time status upd ates
from a radio. An MDT sends Host Att ach/Detach messages to the radio as UDP datagr ams destined for
the UDP Service Address and Serv ice UDP Port of the radio. All respo nses and asyn chronous reports are
returned to the address and port of the requesting host. Refer to the ECP Control and Status Services
Feature Manual, 14221-7200-6040, for more information on this feature.
