2 RF ENERGY EXPOSURE INFORMATION
2.1 RF ENERGY EXPOSURE AWARENESS, CONTROL INFORMATION,
AND OPERATION INSTRUCTIONS FOR FCC OCCUPATIONAL USE
REQUIREMENTS
Before using your mobile two-way radio, read this important RF energy awareness and control
information and operational instructions to ensure compliance with the FCC’s RF exposure
guidelines.
This radio is intended for use in occupational/controlled conditions, where users have full
knowledge of their exposure and can exercise control over their exposure to meet FCC
limits. This radio device is NOT authorized for general population, consumer, or any
other use.
CAUTION
Changes or modifications not expressly approved by Harris Corporation could void the
user's authority to operate the equipment.
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses RF energy or radio waves to send and
receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited
to, electric power, sunlight, and x-rays. RF energy, however, should not be confused with these other
forms of electromagnetic energy, which, when used improperly, can cause biological damage. Very high
levels of x-rays, for example, can damage tissues and genetic material.
Experts in science, engineering, medicine, health, and industry work with organizations to develop
standards for exposure to RF energy. These standards provide recommended levels of RF exposure for
both workers and the general public. These recommended RF exposure levels include substantial margins
of protection. All two-way radios marketed in North America are designed, manufactured, and tested to
ensure they meet government established RF exposure levels. In addition, manufacturers also recommend
specific operating instructions to users of two-way radios. These instructions are important because they
inform users about RF energy exposure and provide simple procedures on how to control it. Please refer
to the following websites for more information on what RF energy exposure is and how to control your
exposure to assure compliance with established RF exposure limits.
http://www.fcc.gov/oet/rfsafety/rf-faqs.html
http://www.osha.gov./SLTC/radiofrequencyradiation/index.html
2.2 FEDERAL COMMUNICATIONS COMMISSION REGULATIONS
Your Harris Corporation M7300 mobile two-way radio is designed and tested to comply with the FCC RF
energy exposure limits for mobile two-way radios before it can be marketed in the United States. When
two-way radios are used as a consequence of employment, the FCC requires users to be fully aware of
and able to control their exposure to meet occupational requirements. Exposure awareness can be
facilitated by the use of a label directing users to specific user awareness information. Your Harris
Corporation M7300 two-way radio has an RF exposure product label. Also, the M7300 Installation and
Operator’s Manuals include information and operating instructions required to control your RF exposure
and to satisfy compliance requirements.
MM-014716-001, Rev. H
10
2.3 COMPLIANCE WITH RF EXPOSURE STANDARDS
Your Harris Corporation M7300 mobile two-way radio is designed and tested to comply with a number of
national and international standards and guidelines (listed below) regarding human exposure to RF
electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure limits for
occupational/controlled RF exposure environment at duty factors of up to 50% talk-50% listen and is
authorized by the FCC for occupational use. In terms of measuring RF energy for compliance with the
FCC exposure guidelines, your radio antenna radiates measurable RF energy only while it is transmitting
(talking), not when it is receiving (listening) or in standby mode.
Your Harris Corporation M7300 mobile two-way radio complies with the following RF energy exposure
standards and guidelines:
• United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR §§
2 sub-part J.
• American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE)
C95.1-2005.
• Institute of Electrical and Electronic Engineers (IEEE) C95.1-2005.
• IC standard RSS-102, Issue 2, 2005: “Spectrum Management and Telecommunications Radio
Standards Specification. Radiofrequency Exposure Compliance of Radiocommunication Apparatus
(All Frequency Bands).
CAUTION
Table 2-1 lists the recommended minimum lateral distance for a controlled environment
and for unaware bystanders in an uncontrolled environment, from transmitting types of
antennas (i.e., monopoles over
a ground plane, or dipoles) at rated radio power for
mobile radios installed in a vehicle. Transmit only when unaware bystanders are at least
the uncontrolled recommended minimum lateral distance away from the transmitting
antenna.

3 OPERATION SAFETY RECOMMENDATIONS
3.1 TRANSMITTER HAZARDS
WARNING
The operator of any mobile radio should be aware of certain hazards common to
the operation of vehicular radio transmitters. A list of several possible hazards is
given:
• Explosive Atmospheres – Just as it is dangerous to fuel a vehicle with the motor running, similar
hazards exist when operating a mobile radio. Be sure to turn the radio off while fueling a vehicle. Do
not carry containers of fuel in the trunk of a vehicle if the radio is mounted in the trunk.
Areas with potentially explosive atmosphere are often, but not always, clearly marked. Turn off your
radio when in any area with a potentially explosive atmosphere. It is rare, but not impossible that the
radio or its accessories could generate sparks.
• Interference to Vehicular Electronics Systems – Electronic fuel injection systems, electronic anti-
skid braking systems, electronic cruise control systems, etc., are typical electronic systems that can
malfunction due to the lack of protection from radio frequency energy present when transmitting. If
the vehicle contains such equipment, consult the dealer and enlist their aid in determining the
expected performance of electronic circuits when the radio is transmitting.
• Electric Blasting Caps – To prevent accidental detonation of electric blasting caps, DO NOT use
two-way radios within 1000 feet of blasting operations. Always obey the “Turn off Two-Way
Radios” signs posted where electric blasting caps are being used. (OSHA Standard: 1926-900)
• Liquefied Petroleum (LP) Gas Powered Vehicles – Mobile radio installations in vehicles powered
by liquefied petroleum gas with the LP gas container in the trunk or other sealed-off space within the
interior of the vehicle must conform to the National Fire Protection Association standard NFPA 58
requiring:
The LP gas container and its fittings.
Outside filling connections shall be used for the LP gas container.
The LP gas container shall be vented to the outside of the vehicle.
3.2 SAFE DRIVING RECOMMENDATIONS
(Recommended by AAA)
• Read the literature on the safe operation of the radio.
• Keep both hands on the steering wheel and the microphone in its hanger whenever the vehicle is in
motion.
• Place calls only when the vehicle is stopped.
• When talking from a moving vehicle is unavoidable, drive in the slower lane. Keep conversations
brief.
• If a conversation requires taking notes or complex thought, stop the vehicle in a safe place and
continue the call.
• Whenever using a mobile radio, exercise caution.
MM-014716-001, Rev. H

4 OPERATING RULES AND REGULATIONS
Two-way FM radio systems must be operated in accordance with the rules and regulations of the local,
regional, or national government.
In the United States, the M7300 mobile radio must be operated in accordance with the rules and
regulations of the Federal Communications Commission (FCC). As an operator of two-way radio
equipment, you must be thoroughly familiar with the rules that apply to your particular type of radio
operation. Following these rules helps eliminate confusion, assures the most efficient use of the existing
radio channels, and results in a smoothly functioning radio network.
When using your two-way radio, remember these rules:
• It is a violation of FCC rules to interrupt any distress or emergency message. As your radio operates
in much the same way as a telephone “party line,” always listen to make sure that the channel is clear
before transmitting. Emergency calls have priority over all other messages. If someone is sending an
emergency message – such as reporting a fire or asking for help in an accident – KEEP OFF THE
AIR!
• The use of profane or obscene language is prohibited by Federal law.
• It is against the law to send false call letters or false distress or emergency messages. The FCC
requires that you keep conversations brief and confine them to business. To save time, use coded
messages whenever possible.
• Using your radio to send personal messages (except in an emergency) is a violation of FCC rules.
You may send only those messages that are essential for the operation of your business.
• It is against Federal law to repeat or otherwise make known anything you overhear on your radio.
Conversations between others sharing your channel must be regarded as confidential.
• The FCC requires that you identify yourself at certain specific times by means of your call letters.
Refer to the rules that apply to your particular type of operation for the proper procedure.
• No changes or adjustments shall be made to the equipment except by an authorized or certified
electronics technician.
NOTE
Under U.S. law, operation of an unlicensed radio transmitter within the jurisdiction of
the United States may be punishable by a fine of up to $10,000, imprisonment for up to
two (2) years, or both.
5 OPERATING TIPS
The following conditions tend to reduce the effective range of two-way radios and should be avoided
whenever possible:
• Operating the radio in areas of low terrain, or while under power lines or bridges.
• Obstructions such as mountains and buildings.
• In areas where transmission or reception is poor, some improvement can be obtained by moving a few
yards in another direction or moving to a higher elevation.

7 PRODUCT DESCRIPTION
The M7300 mobile is a state-of-the-art radio designed to meet the critical demands of its users. The
M7300 mobile supports multiple operating modes, including OpenSky® digital trunked operation
(700/800 MHz radios only), Enhanced Digital Access Communications System (EDACS®) or ProVoiceTM
trunked modes, P25 digital trunked mode, P25 digital conventional mode, and analog conventional mode.
The optional Global Positioning System (GPS) receiver module can provide standard GPS formatted data
over the air for vehicle tracking systems.
Data Encryption Standard (DES) and the optional Advanced Encryption Standard (AES) are available for
maximum communications security.
The M7300 radio uses the CH-721 Control Head which is available in two models: System and Scan. The
display is designed to maximize readability and ease of use. The CH-721 utilizes a 3-line 12-character
alphanumeric display with large buttons, volume knob, and channel knob, providing a user-friendly
interface.
The CH-721 control head can be mounted with the radio (Front Mount) or it can be mounted and operated
remotely. For remote mount installations configured with a CH-721 control head, all normal radio
operations and interfaces can be handled via the control head connected to the radio unit via a 3-wire
Controller Area Network (CAN) cable. Two control heads may be attached to a radio. Each control head
provides a serial access point for data and any one (only one at a time) can be connected to a data device
such as a personal computer.
Where multiple control heads are connected or where a dash-mount radio is installed with an additional
remote control head, the following features are available from each position:
• Outgoing voice calls can be initiated. Either control head can initiate a call but only one can talk at a
time. The other connected control head hears both sides of the conversation.
• Incoming and outgoing audio can be heard. (Outgoing audio is not broadcast at the source position.)
• Independent audio control is available.
• Radio settings such as talk group, scan mode etc., can be controlled. (Any connected control head can
override the radio settings of another connected control head.)
• Comfort settings, such as volume and display brightness that are applicable to the individual control
head can be adjusted and cannot be overridden by another control head.
• An optional intercom function is available between control units. Audio is broadcast to ALL
connected control heads.

9.2 POWER UP AND VOLUME CONTROL
9.2.1 Power Up
1. Rotate the Power On-Off/Volume Control knob clockwise to power on the radio. The display
illuminates when the radio powers up.
2. Wait for the power-up sequence to complete, which takes approximately ten (10) seconds.
During this time, if enabled for auto registration, the radio is provisioned with a customized user
personality designed for the user’s specific needs by the OpenSky network administrator.
If this personality contains encrypted talk groups or if the user is authorized for, and intends to use,
manual encryption, User Login must be performed unless the radio has been programmed to auto-
login. This requires a system model control head so that the User ID and password can be entered.
3. When provisioning is complete, the radio displays the Dwell Display.
If User Login is required, the bottom line of the Dwell Display flashes the message “Pls Login.”
9.2.2 Volume Control
Turn the Power On-Off/Volume Control knob clockwise to increase the volume and counter-clockwise to
decrease the volume. The radio sounds a tone to indicate the current volume level.
9.3 SELF-TEST
After power-up, the M7300 radio undergoes a multi-function automatic registration procedure. As many
as sixteen (16) possible radio profiles are downloaded to the radio from the network in response to the
User’s ID.
9.4 LOGIN TO THE NETWORK
Login occurs either automatically (auto registration) if the radio has a valid registration or, if enabled and
authorized for encryption (Section 9.32), requires the user to enter a User ID and password.
If encryption is enabled and authorized on the radio, the user is prompted to “Pls Login” with the *1 login
command, a User ID, and password [System Model Control Head required].
1. Press *1 (Login command).
2. Enter the full 10-digit User ID.
3. Press the # key.
4. Enter the password.
• If the radio is configured for alpha-numeric passwords and the password has consecutive
duplicate numbers (“MES33” for example), enter # between the consecutive duplicate numbers
so the radio does not interpret the entry as a letter (“D” in this example).
• If the radio is configured for numeric-only passwords, do not enter # between duplicated
numbers.
5. Press the # key twice.
MM-014716-001, Rev. H
29
The User ID may be remembered from the previous login. (Refer to Section 9.5 for further details
regarding log off commands.) The password is established before the radio is put into operation. Contact
the local OpenSky network administrator for more information.
NOTE
If necessary, contact radio system administration personnel for login assistance and/or
radio-specific login instructions.
9.5 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 remembered by the radio so only the password is
needed at next login. Manually log off by pressing *0## (requires System Model).
9.6 TURN THE RADIO OFF
To turn the radio off, rotate the Power On-Off/Volume Control knob counter-clockwise. In multiple
control head installations, turning off the last powered-up control head also automatically turns off the
radio.
If enabled via programming, several user-selected radio settings (i.e., scan mode, pre-set buttons, and side
tone levels) are maintained for the next operational session. At the next radio power-up, maintained
settings automatically restore, along with the network personality settings. In multiple control head
installations, settings are maintained for each control head position.
NOTE
If power is abruptly disconnected from the radio prior to executing the correct turn-off
procedure, user-selected radio settings and last-tuned channel information are lost. This
can extend the time required for the radio to register with the network upon the
subsequent power-up.
9.7 MENU DISPLAY AND CONTROL AREA
Following power-up, the radio display shows the default talk group (Figure 9-3). , OPT/OPTION,
or CLR/CLEAR changes the display to the next available menu. In many cases, the dwell display
automatically re-appears after no menu buttons are pressed for a short period of time (between 10 and 30
seconds). For some menus such as the GPS and User ID menus, this does not occur unless the menu
up/down buttons are pressed.
When the dwell display is active, it changes to reflect the current profile, received talk group/caller ID
(when available), or channel. The second line of dwell menu changes when the user presses the MENU
button.
The radio’s display is highly interactive. It responds in the top and bottom text lines as the user presses
the menu buttons to scroll through the menu loop and the entries for each menu.

9.11 PERSONALITY
As illustrated in Figure 9-4, 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 comprehensive 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 and at user log-in. Each personality can contain up
to sixteen (16) profiles and each profile can contain up to sixteen talk groups.
9.11.1 Profiles
As stated above, each profile can contain up to sixteen (16) talk groups. A profile also defines the radio’s
emergency behavior. All transmissions are made on the selected talk group (displayed on the top line of
the dwell display). The user can change the selected talk group to any of the other talk groups within the
profile.

9.11.2 Talk Groups
A talk group represents a set of users that regularly need to communicate with 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.

9.14 DUAL-TONE MULTI-FREQUENCY
Dual-Tone Multi-Frequency (DTMF) is the system used by touch-tone telephones. DTMF assigns a
specific tone frequency to each key so a microprocessor can easily identify its activation. The radio
supports DTMF with a system model control head (Figure 9-1). This allows for specific tasks such as
entering a user ID and password, or Selective Calling.
When a key on the DTMF keypad is pressed, the DTMF tone is played through the radio’s speaker.

9.16 CHANGE THE ACTIVE PROFILE
The radio can store up to sixteen (16) standard profiles, one of which is the currently active profile. To
change the currently active profile:
1. Scroll through the menu until “ProfileMenu” is displayed.
2. Use to scroll through the list of available profiles.
3. Profile becomes active when selected for longer than two (2) seconds, when the MENU is pressed, or
when the menu is changed.
9.17 ENABLE/DISABLE VOLUME SIDE TONE
The Volume Side Tone sounds when adjusting the volume control.
To enable or disable this tone:
1. Power off the radio.
2. Press and hold the B button while turning the radio on.
9.18 CHECK OR CHANGE THE SELECTED TALK GROUP
Each profile stored in the radio can have up to sixteen (16) talk groups. One talk group within the
currently active profile is set as the “selected talk group.” For the radio user, the selected talk group is
typically the focus of most voice transmissions and receptions. There are two ways to change the selected
talk group:
First Method:
1. Scroll through the menu until “TalkGrpMenu” appears on the bottom line of the display. The
currently selected talk group appears in the top line of the display.
2. Use to scroll through the available list of talk groups in the active profile. This list is
determined by the OpenSky network administrator.
Second Method:
From the dwell display, use the talk group selection knob or to scroll through the available list of
talk groups in the active profile.
9.19 ADJUST DISPLAY AND BUTTON BACKLIGHT BRIGHTNESS
1. Scroll through the menu until “Bright Menu” appears.
2. Use to increase or decrease brightness. Display and button backlight brightness immediately
dims or brightens.
Or
If enabled via programming, increases/decreases brightness.
9.20 STEALTH MODE
For some users, it is important to be able to turn off the radio’s display lights, button backlighting, volume
and side tones, but not radio traffic. For example, in covert operations, lights and sounds could
MM-014716-001, Rev. H
40
inadvertently expose an otherwise unobservable radio user. For this purpose, the radio has a Stealth
feature that disables the radio display light, indicator light, and audible side tones.
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. All buttons are disabled except for PTT, Emergency, 2# and MENU.
Since the screen is blank the user cannot see the result of other button presses.
9.20.1 Enable Stealth Mode
1. Scroll through the menu until “StealthMenu” appears.
2. To immediately turn Stealth Mode on, press (+) or (-) with .
Or
Press quick button command 2# on the System Model control head.
9.20.2 Disable Stealth Mode
To turn Stealth Mode off, press quick button command 2# or the MENU button on the radio’s front panel.
9.21 ADJUST SIDE TONE AUDIO LEVEL
The radio sounds confirming tones called “side tones” when its buttons are pressed. Most users find this
audible confirmation helpful when navigating the menus. Side tone audio level can be adjusted or turned
completely off using the “Side Menu.”
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.
To temporarily disable the side tones that could expose the user’s presence and position, use the menu
buttons to access the “Side Menu” and select “Off” from the menu choices.
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, access the “Side Tone” menu and select a setting
other than “off.”
Use the following procedure to set side tone level:
1. Scroll through the menu until the “Side Menu” appears in the bottom line of the display.
2. Use to change to the desired level (Off, Low, Medium, and High). To turn side tones
completely off, use the “Off” setting.
MM-014716-001, Rev. H

9.22 CHANGE OPERATING MODE
1. Scroll through the menu until “App Mode” appears in the bottom line of the display.
2. Use to choose an available mode. Press MENU and confirm (Y/N) with and press
MENU again.
Or
Preset button C can be configured via programming to reboot the radio into a particular application mode.
Or
Quick Button command 1# transitions the radio to ECP mode. If ECP mode is not loaded in the radio, the
radio displays “No App.”
9.23 RECEIVE AND TRANSMIT VOICE CALLS
As soon as the radio completes the startup/login/provision/self-test sequence and registers on the
OpenSky network, voice calls from talk groups in the active profile are audible.
9.23.1 Receive a Voice Call
NOTE
The Alias/User ID/Talk Group name are only displayed if that dwell display option is
selected using the MENU button. For example, if the user sets the dwell display option
to profile, the profile continues to be displayed when a call is received.
No action is required to receive a voice call. The display responds to incoming voice calls as follows:
• When the dwell display is set to received talk group, the scan mode is Normal or Fixed:
a. If the received talk group matches the selected talk group, 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 talk 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 received, the alias (if available) or the user
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.
NOTE
A radio receiving a System All Call displays “All Call” instead of the alias. A radio
not transmitting on a talk group in emergency status drops all other calls to scan into
an All Call.
Refer to Section 9.27 for detailed information on talk group scanning. Refer to Section 9.32 for detailed
information regarding sending and receiving encrypted calls.
MM-014716-001, Rev. H
42
9.23.2 Transmit a Voice Call
Transmit a voice call as follows:
1. Turn the radio on.
2. If required, login to the network using a user ID and password (see Section 9.4).
3. Select the desired talk group for transmitting on.
4. Press and hold the Push-to-Talk (PTT) button on the hand-held microphone, pause for a moment,
and then speak normally. For maximum clarity, hold the microphone approximately 2 inches from the
mouth and do not shout or whisper into it. If the call is queued by the network, wait for the grant tone
to sound before speaking.
5. Release the PTT button when finished speaking.
Refer to Section 9.32 for detailed information regarding sending and receiving encrypted calls.
9.24 ADJUST AUDIO TREBLE LEVEL
The tone of received signals can be adjusted using the radio’s “Treble Menu” as follows:
1. Scroll through the menu until “Treble Menu” appears. The radio’s current treble level setting
indicates in the top line of the display. There are four levels available: low, medium, medium-high,
and high.
2. Use to increase or decrease treble level.
3. Press the MENU button or wait a few seconds to return to the Dwell Display.
9.25 INTERCOM MODE
The optional intercom mode gives users at multiple control heads connected to the same radio the ability
to communicate with each other without transmitting over-the-air. Turn intercom mode on and off using
the “INTERCOM” menu as follows:
1. Scroll through the available menu items until “INTERCOM” appears in the display.
2. Use to toggle between “On” and “Off.”
When intercom mode is turned on:
• Incoming voice calls override intercom communications for the duration of the voice call. The radio
and associated control heads remain in intercom mode and intercom communications resume when
the voice call ends.
• “TG: INTERCOM” appears in the control head’s display when talking on the intercom. This indicates
microphone audio is not sent out on the selected talk group; rather, it remains localized between the
radio control positions (i.e., the control heads connected to the mobile radio).
• If a call exists on the currently selected talk group when a PTT button is pressed at one of the control
heads, “TG: in use” appears in the display to indicate intercom mic audio cannot preempt the call on
the talk group.
MM-014716-001, Rev. H
43
CAUTION
A user at a radio with only one control head/front panel can turn intercom mode on. In
this case, pressing the microphone’s PTT button does NOT
send microphone audio
anywhere.
9.26 TALK GROUP LOCK OUT
There are two ways of focusing voice communications by suppressing calls from talk groups in the
currently active profile:
1. No Scan. By turning scan off (selecting “No Scan” via the “ScnModeMenu”), only the selected talk
group is audible.
2. Lock Out. By locking out selected talk groups, the “chatter” of the locked out talk groups cannot be
heard. This focuses the user’s scanning resources to calls only on desired talk groups.
Talk group lock out is a scan-related feature. With lock out, one or more talk groups in the active profile
can be temporarily disabled from being scanned. Calls are not received on locked-out talk groups. Lock
out settings are not retained between profile changes or when the radio is power cycled.
NOTE
Lock out is a listening (receive) function and only blocks received calls on locked out
talk groups. Lock out does not affect transmit capability. The above methods 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.
NOTE
P1 and P2 talk 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 is automatically 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.
9.26.1 Lock Out a Talk Group
1. Scroll through the menu until “LockOutMenu” appears in the bottom line of the display. The name of
a talk group in the currently active profile appears in the top line.
2. Use to scroll through the list of talk groups, if any, until the desired talk group for lock out
appears in the top line of the display.
3. Press the MENU button to lockout the displayed talk group. A less than symbol (<) appears next to
the talk group’s name.
4. Repeat steps 2 and 3, as needed, to lock out additional talk groups.
The dwell display re-appears a few seconds after button presses end.
While scrolling through talk groups in the active profile, the only talk groups that appear in the
“LockOutMenu” are those in the active profile.
MM-014716-001, Rev. H
44
9.26.2 Unlock a Talk Group
1. Scroll through the menu until “LockOutMenu” appears in the bottom line of the display. The name of
a talk group in the currently active profile appears in the top line.
2. Use to scroll through the list of talk groups, if any, until the talk group desired for unlocking
appears in the top line of the display. A less-than symbol (“<”) appears next to the name of a talk
group that is currently locked out.
3. Press the MENU button to unlock the talk group. The less-than symbol (“<”) next to the name of the
talk group disappears. The dwell display appears as soon as the radio acknowledges the selection.
NOTE
• Changing the active profile removes any lock outs you have made.
• Turning off the radio removes any lock outs you have made.
9.27 SCANNING
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 radio scans voice calls for all of profiles in the radio personality, no
matter which profile is or becomes active.
As described in Table 9-7, the choice of scanning mode changes the span of communications with all the
talk groups in the radio’s profiles, but does not affect interaction with the talk groups.
Table 9-7: Scan Modes
SCAN MODE EXPLANATION
No Scan
Eliminates distractions.
Full communications (transmit and receive) on selected talk group.
No calls received from other talk groups.
Normal
(Default)
The user can scan all talk groups in the active profile that are not locked out as long as there is
demand on the site.
Priority (P1 and P2) groups are user selectable.
Receive calls from more than one talk group, if available from the current site.
Allows dragging of the selected talk group, P1, P2, and default emergency talk groups to the site on
which the radio is registered. (If other calls are available at the site, they also can be heard but they
are 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.
Fixed
Functions the same as Normal Scan Mode, except the priority groups are fixed to the selected
profile’s pre-defined P1 and P2 groups (configured via the UAS).
MM-014716-001, Rev. H
45
9.27.1 Check or Change Active Scan Mode
The currently active scan mode does not appear in the dwell display. To check it, access “ScnModeMenu”
and observe it in the top line of the display. To change the active scan mode:
1. Scroll through the menu until “ScnModeMenu” appears in the display.
2. Use to scroll through the scan options until the desired mode appears. See Table 9-7.
Or
Use the quick button option 3#.
9.27.2 Scan Priority
The following lists the scanning priority order (from highest to lowest):
• System All Call
• Selected talk group in emergency state
• Default emergency group in emergency state
• Selected talk group
• Emergency capable group in emergency state
• Priority 1 talk group
• Priority 2 talk group
• Other (non-priority)
9.27.3 Change Priority 1 and Priority 2 Talk Groups
Follow this procedure to set talk groups in the current profile as the Priority 1 or Priority 2 talk group:
1. Scroll through the menu until “Priority1” or “Priority2” appears in the bottom line of the display
(Priority 1 group has higher priority than the Priority 2 group. The talk group currently set as the
priority talk group appears in the top line of the display.
2. Use to select a new priority talk group.
3. Press the MENU button to set the newly selected talk group as the priority talk group.
9.28 MAKE SELECTIVE CALLS
Selective Calling is a feature that allows two radio units to obtain and utilize an independent voice path
for a private call. Radios can be configured to both initiate and receive Selective Calls or to only receive
Selective Calls.
In the OpenSky system, a source radio can be configured to initiate Selective Calls through a pre-
programmed list in memory. This method uses the “speed dial list” set up by the OpenSky network
administrator and provisioned as part of the registration process.
In addition, a properly equipped source radio can initiate a Selective Call to any radio in the system by
entering the ten-digit voice user ID (which looks like a telephone number) of the target device. Entering a
Selective Call number without using the speed dial feature requires a system model control head (Figure
9-1). See Section 9.14 for more detail.
MM-014716-001, Rev. H
46
NOTE
Selective Calls are terminated if an emergency is declared. The network limits Selective
Calls to ten (10) minutes maximum.
Table 9-8 lists and defines the messages that may be displayed by the radio during a Selective Call.

9.29 SELECTIVE ALERT
Selective alert messaging is an OTP feature allowing one of up to eight (8) pre-programmed text
messages (refer to Section 9.29.3) to be sent from one radio to another. The user specifies a destination
radio’s User ID, selects one of the pre-programmed text messages, and then transmits it to the destination
radio. The message delivery system adds 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. Refer to Table 9-9 for a list of possible status messages.
The first few characters of a message are part of the message text entered when the message is
programmed. This programming is performed by the system or network administration personnel.
Messages successfully received by the destination radio are stored until deleted or until the radio is power
cycled.

Press the # button or (-) using to reject an incoming Interconnect Call.
9.31 EMERGENCY COMMUNICATIONS
The M7300 mobile radio can transmit both emergency voice calls and emergency alerts over the entire
network. OpenSky handles emergency calls and alerts with the highest priority.
For critical voice communications, an emergency call can be raised on the default talk group or the
currently selected talk group by “declaring” an emergency on the talk group. The exact talk group is
determined by the currently active profile. After successfully declaring an emergency on a talk group, the
declaring radio’s microphone remains “hot” for a predetermined amount of time. In other words, the radio
transmits audio for a period of time even when the microphone’s PTT button is not pressed. An
emergency talk group is provided greater priority and infinite hang-time by the radio system’s
infrastructure. Hang-time is the maximum duration of quiet time between transmissions on the talk group
before the infrastructure assets are automatically taken away. Because an emergency call is handled on a
talk group, it is received by all radios and consoles monitoring the talk group.
An emergency alert is a data message sent by the radio to the MIS console (or any console capable of
receiving it). It identifies the radio declaring the emergency, and the radio’s location (if the radio is
equipped with a GPS receiver). Voice audio is not automatically transmitted during the emergency if the
administrator configures the radio for alert notification only.
9.31.1 Declare an Emergency Call or Alert
1. Press the red emergency button on the radio to enter emergency mode. The emergency is raised after
the emergency raise delay [default is one (1) second].
• If the active profile of the unit initiating the emergency is configured for Emergency Alert, the
emergency alert signal is sent to registered alert servers, such as the dispatcher console.
• If the active profile of the unit initiating the emergency is configured for Emergency Call, the
talkgroup is placed into emergency status notifying other radios and the emergency alert signal is
sent to the dispatcher console.
• If the emergency behavior of the active profile is Current, the active, selected voice group
becomes the default emergency voice group.
• If the emergency behavior of the active profile is Default, the radio moves to the default
emergency voice group of the profile and this talk group becomes the select talk group.
2. The display alternates between “Emergency” and whatever option is selected for the 2nd line of the
dwell display.
If the attempt is unsuccessful, “E-PEND” flashes periodically and a retry is queued for 10 seconds. If
unsuccessful because of lost sync, retry occurs immediately upon reacquiring sync. On each retry attempt,
radio temporarily displays “E-RETRY.” This process repeats until the emergency is successfully
declared.
9.31.2 Silent Emergency
When this feature is enabled and an emergency call or alert is declared by pressing the emergency button,
the radio does not play a tone and displays an abbreviated emergency message (default is EBA). This
feature is enabled or disabled via programming or via the menu.
MM-014716-001, Rev. H
51
If the Silent Emergency feature is enabled or disabled via programming, the setting
survives power cycle. Enable/Disable selection via the menu does NOT survive power
cycle and the enable/disable state reverts to the programmed setting at power up.
9.31.3 Clear an Emergency Call or Alert
Check with the system administrator to ensure that the radio is programmed to allow an
emergency to be cleared.
If enabled via programming, clear an emergency by:
1. Pressing and holding the CLR/CLEAR button and simultaneously pressing the emergency button.
2. After the Emergency Cleared Tone sounds, release both buttons.
If the radio is in Stealth Mode, clearing the emergency takes the radio out of Stealth Mode.
9.31.4 Receive an Emergency Call
Upon receiving an emergency call declared by another radio:
• An emergency tone sounds in the radio’s speaker/headset (three short high-pitched beeps).
• “EMERGENCY” flashes in the display if the radio is not in stealth mode. When receiving voice in an
active emergency, the flashing “EMERGENCY” is inhibited so that the alias of the sender can be
seen.
• On receiving radios with the emergency talk group selected, the alias of the sending party is displayed
for 5 seconds during the open-mic period, then the word “Emergency” flashes on the second line of
the display and continues until the emergency state ends.
• If scan mode is set to “No Scan” and the emergency was declared on the selected talk group, audio on
the emergency talk group is heard in the speaker/headset. See page 44 for additional information on
“No Scan” operation.
• If scan mode is set to “No Scan” and the emergency was declared on a talk group other than the
selected talk group, the emergency talk group (identified by an “*”) must be selected before audio on
it is heard in the speaker/headset.
• If scan mode is set to “Normal” and the emergency was declared on the selected talk group, the
selected/emergency talk group’s name remains in the top line of the display. Audio on the emergency
talk group is heard in the speaker/headset.
• If scan mode is set to “Normal” and the emergency was declared on a talk group other than the
selected talk group, the emergency talk group’s name appears in the bottom line of the display. Audio
on the emergency talk group is heard in the speaker/headset.
• The declaring radio's alias appears in the bottom line of the display when the emergency talk group is
selected.
• An emergency call can be dismissed as described in the following section.
MM-014716-001, Rev. H
52
NOTE
A radio declaring an emergency on a talk group has a “hot” mic time period of typically
ten (10) seconds just after it declares the emergency. This time period may be adjusted
by system or network administration personnel on a per radio basis.
9.31.5 Dismiss an Emergency Call
NOTE
An emergency is dismissed for a configurable amount of time only (default = 5 minutes).
To ignore an emergency call declared by another radio user:
1. Scroll through the menu until “EmgDismiss” appears in the display.
2. Press until the talk group in the emergency state appears, as indicated by an asterisk (*)
following the talk group’s name.
3. Press the MENU button.
NOTE
The emergency dismiss timer is cleared when the emergency is cleared.
9.32 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., M7300 mobile radio). This form of encryption provides air-link 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 user.
Manual encryption is initiated by two or more radio users and requires system model control heads. Both
methods of encryption are discussed in the following sections.
9.32.1 Automatic Encryption
For automatic encryption, a network administrator selects the talk group to be encrypted at the interface to
the UAS. Once the talk groups have been selected and identified as secure, credentials for key generation
are generated automatically by the system and provisioned to authorized users. This process requires that
authorized users login to the network and be authenticated. Encryption keys require no manual handling
and are never sent “in the clear” over any network interface or air-link.
1. “Pls Login” appears displayed in the bottom line of the dwell display.
2. Login normally using the keypad on a system model control head to enter User ID and Password.
If a user is engaged in a call on a talk group encrypted at the network administrator level, “Secure Call”
appears in the bottom line of the dwell display if the user is logged in to that talk group.
If a secure call is in progress elsewhere and the user has not logged in, the bottom of the dwell display
alternates between “No Access” and the alias of the radio that is currently engaged in the secure call.
MM-014716-001, Rev. H
53
NOTE
The radio can also be programmed to automatically login and enable encryption.
9.32.2 Manual Encryption (System Model)
Two or more users can manually encrypt a call, if enabled, without an established encrypted talk group. A
pre-determined key is required at each radio.
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.
If two communicating radios have different (manually-
defined) keys, receive audio at
each radio sounds garbled.
With manual encryption enabled, unencrypted radio users on the talk group can still make standard voice
(unencrypted) calls on the talk group. However, if an unencrypted user attempts to transmit on the talk
group when one of the encrypted users is already transmitting on the talk group, the unencrypted radio
sounds a deny tone and “No Access” appears in the display. Also, the encrypted user can hear standard
unencrypted calls, but cannot respond while still manually encrypted.
CAUTION
Do not set a talk group for manual encryption if
it has been set for encryption by the
network administration personnel.
Perform the following to transmit or receive manually encrypted calls:
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 the # key.
4. To end manual encryption, press *33#.
If a user is engaged in a call on a talk group that has been manually encrypted at the radio level, the user
sees “Secure Call” on the bottom of the dwell display.
If a secure (encrypted) call is in progress, and the user has not entered the key, the bottom of the dwell
display alternates between “No Access” and the alias of the radio that is currently engaged in the secure
call.
Once the user has terminated manual encryption, “UnSecure” appears temporarily in the bottom line of
the dwell display.

Press to cancel RTT message selection.
9.36 DYNAMIC REGROUPING
Dynamic regrouping requires that the network administrator determine which radio users should be
formed into an impromptu talk group to respond to particular emergency conditions.
The administrator edits the personalities of the affected radios to include an emergency profile and then
pages the affected radios to re-register with the network to receive their edited personalities.
In response, affected radios automatically re-register to receive their edited personalities. During re-
registration, subscriber equipment defaults to the emergency profile selected by the administrator.

10.9 SYSTEM/GROUP/CHANNEL SELECTION
The M7300 SYSTEM/GROUP/CHANNEL knob and the ramp control are programmable for
maximum flexibility. If the SYSTEM/GROUP/CHANNEL knob is assigned to select groups or channels,
then the ramp control is assigned to select systems. If the SYSTEM/GROUP/CHANNEL knob is
assigned to select systems, then the ramp control is assigned to select groups or channels. System,
group, and channel selection is the primary function for these controls.
Systems or groups can also be selected by pressing SYS or GRP and using the ramp control to
scroll through available options.
10.9.1 System Selection
Several methods, some of which depend on programming, can be used to select a new system. These
procedures are presumed to be starting from the normal receive display.
METHOD 1: If system selection is programmed to the
SYSTEM/GROUP/CHANNEL knob, select a
system by turning the SYSTEM/GROUP/CHANNEL knob to the desired system
position. The display registers the new system name on line 1. If the wrap option is OFF

10.10 LAST SYSTEM/GROUP/CHANNEL RECALL
This feature, enabled through programming, allows the user to recall the last selected system/group after
an emergency or home function or system/group key function. For example, if the Home button (pre-
programmed) is pressed, the radio goes to the designated Home system/group or channel. If the Home
button is pressed again, the radio returns to the previous system/group or channel. At this time, the user
can toggle between the Home system/group or channel and the previous system/group or channel. The
operation is the same for the SG1-SG16 buttons.
10.11 ENCRYPTION
The M7300 mobile radio supports AES and DES encryption. When operating on a group or channel
programmed for encryption, all transmissions are private and the radio receives clear and private signals.
is displayed when encryption is enabled. If the selected group or channel is programmed for auto-
select capability, the mode may be toggled between encrypted and unencrypted by pressing the MENU
key, and then selecting the PRIVATE menu option. Radios programmed for forced encryption do not
allow a change of the transmit mode.
10.11.1 Displaying the Currently Used Cryptographic Key Number

10.11.3 Receive an Encrypted Call
When receiving, the radio automatically switches between clear or encrypted operation. If the
transmission being received is an encrypted transmission, it is decrypted, the receiver unsquelches, and
the message is heard in the speaker. The selected group or channel must be programmed for encryption
and the correct cryptographic key must be loaded into the radio for this to occur.
10.11.4 Transmit an Encrypted Call
1. Select the desired group or channel.
2. Enable encryption by pressing the MENU button and then selecting the PRIVATE menu option, or
press the button on the control head that has been programmed for PRIVATE.
• If the last state of the radio was encryption enabled, then encryption is enabled on power up. In
addition, encryption is enabled if forced operation has been programmed in the radio
• If a group or channel is not programmed for encryption, PVT DIS is displayed if an attempt is
made to enable encryption. It is not possible to operate on this group/channel in encrypted mode.
• If the radio is programmed for forced encryption mode, FRCD PVT is displayed if an attempt is
made to disable encryption. It is not possible to transmit on this group/channel in clear mode.
• If the radio does not have the correct encryption key loaded, NO KEY # is displayed and the call
does not transmit.
3. Continue with standard transmission procedures. An access tone is heard when the PTT button is
pressed.
10.12 MACRO KEY OPERATION
Macro key operation permits the user to accomplish a series of keystrokes with a single "macro"
keystroke. Up to ten (10) macro keys can be defined, each capable of executing up to twenty (20)
keystrokes, to any pushbutton input (i.e., keypad keys, buttons, etc.). Each macro key can be pre-
programmed to activate when pressed or when released. A macro key can also be pre-programmed to
change the keystroke sequence the next time the macro key is activated. For detail operation and
assignment of macro keys, contact your system administrator.
10.13 RECEIVE A CALL
1. Turn the radio on by rotating the POWER ON-OFF/VOLUME knob clockwise (out of detent). A
short alert signal (if enabled through programming) indicates the radio is ready to use.
2. The display shows the last selected or the power up (depending on programming) system and
group/channel names. If the radio is unable to obtain a control channel, line 2 shows CC SCAN.
3. Adjust the volume to the desired level.
4. Select the desired system and group/channel.
5. The radio is now ready to receive calls.
6. When the radio receives a call, it unmutes on the assigned working channel and the BSY indicator
comes on. Line 1 shows GR followed by the logical ID number (if received) of the unit sending the
message, or the associated name if the ID number is found in the individual call list.
MM-014716-001, Rev. H
71
10.14 TRANSMIT A CALL
1. Turn the radio on and set the POWER ON-OFF/VOLUME knob to the desired volume level. Select
the desired system and group/channel.
2. Ensure that conventional channels are not busy by pressing the CLR button to briefly disable any
channel decoding and unmute the receiver, or observe the unlit BSY indicator. If the Channel Busy
Lockout feature is programmed for the selected channel, the radio does not transmit when the channel
is busy.
3. Press and hold the PTT button.
4. When the working channel is assigned, TX and BSY indicators are turned ON and a short beep is
sounded indicating communication can begin.
NOTE
If two or more tones, or a high-pitched tone is heard, the system may be busy and the
call request has been placed in queue or the request has been denied for some reason.
Refer to the Section 10.6 for more details.
5. Hold the microphone approximately 2 inches from the mouth and speak in a normal voice.
6. Release the PTT button when the transmission is complete and listen for a reply.
10.15 CONVENTIONAL FAILSOFT (EDACS)
In the unlikely event of a failure of the EDACS system, communications can take place in conventional
failsoft mode. The radio is automatically directed to a communications channel set up for this purpose.
During this mode of operation, the control unit displays CONV FS in the alphanumeric display. An
increase in activity on the channel during conventional failsoft operation may be noticed, so be careful not
to transmit until the channel is clear.
Operation during conventional failsoft is the same as operation on a conventional system, except that it is
not possible to select a communications channel, or use emergency and special call. When trunking is
restored, the radio is automatically returned to normal operation.
NOTE
Emergency and Special Call are not operational during conventional failsoft. In
addition, the GRP control does not operate.
10.16 EMERGENCY OPERATION
The radio’s emergency behavior varies depending on programming. When an emergency is declared,
scanning stops and only restarts after the emergency is cleared.
10.16.1 Receive an Emergency Call
When receiving an emergency call from the selected group and system, an alert beep sounds and the BSY
indicator illuminates. The message *RXEMER* flashes in the display on line 2 until the emergency
condition is cleared. Follow standard emergency procedures.
MM-014716-001, Rev. H
72
10.16.2 Declare an Emergency
To send an emergency call to the selected system and group (or on an optionally pre-programmed
emergency group), proceed as follows:
1. Press and hold the red emergency button for approximately one second. (This time is programmable
and could be longer or shorter. Check with the system administrator.) The radio transmits an
emergency call request with the radio ID until an emergency channel assignment is received.
2. When the working channel assignment is received, the radio sounds a single beep (Autokey alert
tone) indicating it is ready for voice transmission. *TXEMER* flashes on line 2 in the display until
the emergency is cleared.
3. Press PTT and speak into the microphone in a normal voice.
4. Release PTT when the transmission is complete and listen for a reply.
5. The emergency can be cleared by pressing and holding the CLR button followed by pressing the red
emergency button then releasing both buttons.
10.17 SYSTEM SCAN OPERATION (EDACS AND P25 TRUNKED)
The radio can be programmed with the following System Scan features. These features are automatically
enabled upon radio power up. A key or menu option is also defined to allow the System Scan features to
be toggled during radio operation. This is covered in the Menu Selection and Pre-Programmed Keypad
Key sections. The System Scan state is maintained through system changes but defaults to ON at power
up.
10.17.1 Wide Area System Scan (WA Scan)
The M7300 Series mobile radio can be programmed for Wide Area System Scan operation for multi-site
applications. 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
switches to the new system and sounds an alert tone.
10.17.2 ProScan™
The radio can be programmed for ProScan™ system scan operation for multi-site applications depending
on the version of radio flash code. 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 level. This is
accomplished by enabling 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 adjacency 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’s
signal quality level degrades below a pre-programmed level, the radio begins to look for a better control
channel. Once a control channel that exceeds the pre-programmed parameters is found, the radio changes
to the new system and emits a tone. If the control channel is completely lost, the radio enters Wide Area
System Scanning and searches the programmed adjacent systems until a suitable control channel is found.
10.17.3 Priority System Scan
The radio can also be programmed for Priority System Scan. (To ensure that this feature operates
correctly, the control channel of the priority system must be located on channel one unless you are using
the ProScan algorithm.) The priority system is the desired or preferred system. While receiving the
control channel of the selected system, the radio periodically leaves the selected system and searches for
MM-014716-001, Rev. H
73
the control channel of the priority system at a programmable rate. The programmable rate is defined by
the value in the Priority Scan Time control, (unless the ProScan algorithm is enabled as explained below).
This priority scan timer is reset each time the PTT button is pressed or when a call is received. If the
priority system control channel is found, or meets the predefined ProScan criteria, the radio automatically
switches to the priority system.
10.17.4 When Wide Area System Scan is Enabled
If the radio cannot find the control channel of the selected system and begins Wide Area System Scan, the
radio only scans for the priority system control channel if the priority system is in the WA Scan list.
10.17.5 When ProScan Is Enabled
The radio monitors the priority system and switches to the priority system if the priority system meets the
criteria defined in the “ProScan Options” dialog box. If ProScan is enabled, the rate at which the radio
scans for the priority system is defined by the System Sample Time control.
10.17.6 Menu Selection
Press MENU and then use the ramp control to scroll through the selections until SYS SCAN is
displayed. Then press MENU to toggle the System Scan state. The SYSC ON or SYSC OFF display
message is displayed for two seconds to show the new state.
10.17.7 Pre-Programmed Keypad Key
Press the pre-programmed key and the SYSC ON or SYSC OFF display message is displayed for two
seconds to show the new state.
10.18 SCAN OPERATION
Only groups or channels that are part of the radio's scan list are scanned. Groups/channels are added to the
scan list on a per system basis through programming, the radio keypad, or both, dependent upon
programming. This scan list can be changed by the user from the keypad, unless programmed otherwise.
Each system's scan list is retained in memory when the radio is turned off. The M7300 Series mobile
radio can also be programmed to provide Trunked Priority Group Scan capability, which operates similar
to priority scan in Conventional mode.
The following is a description of programmable scan features that should be helpful in understanding the
scan operation of the radio:
Scan Hang Time - the delay time the radio waits before resuming scan after the push-to-talk is released
or after the carrier has dropped a channel.
TX Select - the group the radio transmits on while scanning. The radio is programmed to transmit on
either the scanned group or the selected group.
Scan List (privileges) - this feature allows or prohibits scan list changes by the user.
P1 Programming - priority group programming is accomplished by one (and only one) of three methods:
• From the keypad, where the Priority programming is not fixed and does not follow the selected
channel.
• Priority 1 group programming follows the selected channel.
• Priority 1 group programming is fixed during PC programming and cannot be changed by the user.
MM-014716-001, Rev. H
74
P1 Always Scan - determines if the Priority 1 Group is always scanned, regardless of the scan state set by
the user.
10.18.1 Add Groups or Channels to a Scan List
1. With scan operation turned off, select the desired group channel to add to the selected scan list.
2. Press (+) or (-) with to display the current priority status of the group on line 1 for a time-out
period.
3. While the status is displayed, press (+) with to add the group/channel to the scan list. is
displayed.
4. Press (+) with a second time to set the group/channel to Priority 2. is displayed.
5. Press (+) with a third time to set the group/channel to Priority 1. is displayed in column 1,
line 1.
The priority level selection sequence only advances the group to the next higher priority level and stops at
priority level 1. To select a lower priority level, the group/channel must be deleted from the scan list and
then added back to the scan list. Each new group/channel added to the scan list starts at the lowest
priority. If the Priority 1 and Priority 2 group/channel are already set and a new group/channel is assigned
as Priority 1 or Priority 2, the previously assigned group/channel changes to non-priority scanning.
10.18.2 Delete Groups or Channels from a Scan List
1. With scan operation turned off, select the desired group/channel to delete from the selected scan list.
2. Press (+) or (-) with . The current scan status of the group/channel is displayed for a time-out
period.
3. Press (-) with to delete the group from the scan list. , or turns off. Any group/channel
that is not in a scan list shows a “blank” when it is the selected group/channel.
10.18.3 Nuisance Delete
A group/channel can also be deleted from the scan list, if it is not the currently selected group/channel, by
pressing (-) with during scan operation while the radio is displaying the unwanted group/channel.
The group/channel is deleted from the scan list in the same manner as if using the steps above. Deletions
performed in this manner do not remain deleted if the radio is turned off and back on.
10.18.4 Turn Scan On
1. Toggle scan operation by pressing SCAN. The SCAN indicator turns on when the radio is scanning.
NOTE
Scanning stops while the microphone is off-hook if the hookswitch feature is enabled
through programming.
2. When a group on the scan list receives a channel assignment, the radio unmutes on the assigned
channel, the BSY indicator comes on and the received scan group is displayed.
MM-014716-001, Rev. H
75
• The radio continues scanning if a new group/channel is selected when scan is on.
• Pressing the PTT button when scan is on causes the radio to transmit on the displayed
group/channel or on the currently selected group depending on programming.
• Pressing up with when scan is on causes the radio to recall the scanned group/channel that
was last received. This group/channel is recalled for a period equal to the scan hang time.
10.18.5 Priority Group/Channel Scanning
When scan is enabled and the Priority 1 and Priority 2 groups/channels have been identified, the radio
listens to calls on those groups/channels and the selected group/channel. While receiving a scanned call,
the radio continues to monitor the selected Priority 1 and Priority 2 group/channel and drops the call if the
selected group/channel or other higher priority call becomes active. During a Priority 2 call, the radio
continues to monitor for a Priority 1 group call.
The radio monitors for Agency and Fleet calls that correspond to the Agency and Fleet associated with
the Priority 1 and Priority 2 groups. Priority Agency and Fleet calls are indicated by displaying AGENCY
or FLEET on the System line of the display and associated Priority 1 or 2 group on the Group line of the
display.
10.18.6 Turn Scan Off
Turn scan operation off by pressing SCAN. The radio resumes operation on the selected group/channel.
10.19 INDIVIDUAL CALLS (EDACS AND P25 MODES)
10.19.1 Receive and Respond to an Individual Call
When the radio receives an individual call, it unmutes on the assigned working channel and turns on the
BSY indicator. Line 1 shows “ID” followed by the logical ID number of the radio sending the message,
or the associated name if the ID number is found in the individual call list. The individual call indicator
displays *INDV* on line 2. The radio can be programmed to ring when an individual call is received. If
enabled, the ring begins five seconds after the caller unkeys and continues until the PTT button, the CLR
button, or IND is pressed.
NOTE
Hookswitch functions the same as CLR key in I-CALL, phone call, and menu modes.
If a response is made to the call prior to the programmed call-back time-out, the call is directed to the
originating unit. If a response is not made before the call-back time-out, the radio returns to normal
receive mode, but * WHC * is displayed. If the caller's ID is not received, UNKNOWN displays for the
duration of the call and there is no call-back hang time.
To respond after the call-back time-out, press the IND key. The radio's display shows the callers ID on the
first line and WHCI=1 on the second line. Pressing the PTT button at this point initiates an individual call
back to the original caller. (If the last call was a group call, the display shows WHCG=1. Pressing the
PTT button places the call as an individual call.)
The radio stores the IDs of the last 10 callers in the Calls Received 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.
MM-014716-001, Rev. H
76
To access the list, press the IND key twice. Use to scroll through the list. Press the MENU key to
display the time elapsed since the call was received.
10.19.2 Call Storage Lists
There are two lists available for call storage in the radio; the calls received list (1-10) and the personality
list (1-99 as defined by the user). When the individual call mode is entered by pressing IND, the calls
received list is available. The user can toggle to the personality list by selecting any key other than DIS or
toggle between the two lists by pressing the IND key. If wrap is enabled, the calls received list wraps on
itself and not into the other list.
The saved call list shows all ten storage locations. If no calls have been received, the saved call list is
empty and the pre-stored list is available upon entering the individual call mode.
When in the saved call list, pressing MENU toggles the time stamp ON and OFF. The time stamp
indicates how long ago the call was received. The display indicates this information as HH:MM:SS where
HH = hours, MM = minutes, and SS = seconds.
When in the pre-stored list, pressing MENU toggles the logical identification (LID) ON and OFF.
10.19.3 Send an Individual Call
The following procedures describe how to initiate and complete an individual call:
1. To select a previously stored individual, select the I-Call mode from the menu or press IND followed
by the ramp control to scroll through the list of stored individuals. While in the individual call
list, the MENU key toggles the display between the call name and the unit ID number. If the
individual is not stored in this list but the individual’s unit ID is known, it can be entered directly
from the keypad.
MM-014716-001, Rev. H
77
2. Press the PTT button. The radio performs the necessary signaling to obtain a communication channel.
When the signaling is complete and the radio is clear to transmit, the TX indicator turns ON and the
channel access tone sounds. Line 1 shows the called individual's name if found in the list of stored
individuals or ID followed by the logical ID number of the unit being called. The message *INDV*
displays on line 2. Proceed with the message.
10.20 SCAT™ OPERATION
A SCAT (Single Channel Autonomous Trunking) System operates with the same set of features as a
standard EDACS system. The only significant user change relates to the BSY indicator. Since only one
channel, operating as both control and working channel, exists in a SCAT System, the BSY indicator is
ON when the SCAT channel is in the working channel mode. When the transmission on the channel is
completed, the indicator turns OFF and indicates the return of SCAT control channel signaling.
10.21 TELEPHONE INTERCONNECT CALLS (EDACS AND P25)
10.21.1 Receive a Telephone Interconnect Call
Receiving a telephone interconnect call is identical to receiving an individual call. See the DTMF
Overdial Operation section if access to services requiring "over-dial" is needed. Overdial operations are
available for any special call whether it is an individual call or a telephone interconnect call.
10.21.2 Send a Telephone Interconnect Call
Use the following procedures to initiate and complete a Telephone Interconnect call:
1. To select a previously stored phone number, select phone call mode from the menu, press PHN and
use the ramp control to scroll through the list of stored phone numbers. While in the phone
call list, the MENU key toggles the display between the phone call name and the phone call number.
If the phone number is not stored in this list but the phone number is known, it can be entered directly
from the keypad. If necessary, a pause can be entered by pressing and holding 0-9, (*), or (#) until an
underscore appears in the display.
2. Press and release the PTT button; the radio performs the necessary signaling to obtain a
communication channel. When the signaling is complete and the radio is clear to transmit, the TX
indicator turns on and the channel access tone sounds. Line 1 shows the accompanying name if
selected from the list of stored numbers or the phone number if entered directly. The message
*PHONE* is displayed on line 2. The radio then automatically transmits the programmed number
stored in the special call queue.
3. Telephone ringing is heard. When someone answers the phone, press the PTT button and speak into
the microphone. Release the PTT button to listen to the caller. Unsuccessful interconnect signaling
returns the radio to the normal receive mode and the number remains displayed until the special call is
cleared by pressing the CLR button or the time-out expires or another group or system is selected.
4. To terminate the call, momentarily press the CLR button.
NOTE
The M7300 Series mobile radio is capable of half-
duplex conversation only. The
caller’s message can only be sent if the PTT button is pressed (the radio is
transmitting) and the caller can only be heard by the person being called when the PTT
is released (the radio is receiving).
MM-014716-001, Rev. H
78
10.21.3 DTMF Overdial/Conventional Mode Telephone Interconnect
Once the radio has established a connection to the public telephone system, it may be necessary to "over-
dial" more digits to access banking services, answering machines, credit card calls, or other types of
systems that require DTMF (Dual-Tone Multi-Frequency) access digits. Overdial operation can also be
used to initiate a telephone interconnect call via DTMF signaling if a dial tone has already been accessed
on the system. This is the method that is used for making a telephone interconnect call while operating in
the conventional mode but also functions 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 or stored by the operator in the first ten phone list entries. These numbers are accessed by
pressing PHN.
The following steps are required to dial these numbers:
1. Follow the procedure in Section 10.21.2 to establish a connection to the telephone system or consult
the system administrator for the procedure to access a dial tone on the trunked or conventional
system.
2. Overdial numbers are transmitted using either method as follows:
METHOD 1:
Press and hold PTT while entering the overdial number sequence from the keypad.
This method sends DTMF tones during individual, telephone interconnect, trunked
group, or conventional channel calls. Anytime the PTT button is pressed and held,
the keypad is enabled for DTMF entry.
METHOD 2: Press PHN to access
a stored number from the phone list or to directly enter the
overdial digits. Press PTT to send the overdial sequence once. If the number needs to
be transmitted again it must be selected or entered again (this prevents unwanted
numbers from being sent the next time the PTT button is pressed during the call).
This overdial select/entry mode remains active until the call is dropped, cleared, or MENU is pressed. The
overdial select/entry mode can be re-entered if the call is still active by pressing PHN.
10.21.4 Programmable Entries
Individual call ID numbers, telephone numbers and other number sequences for overdialing are stored in
the special call lists when programming the radio. The first ten entry locations of these lists can be
changed by the radio operator. The keypad is used when adding, changing, and storing numbers in these
entry locations.
Use the following procedure to store a number in one of the first ten entries of a special call list:
1. Press IND or PHN to enter the individual call list or the phone call list.
2. Scroll through the list using the ramp control until one of the first ten (10) entries is reached.
NO ENTRY is displayed if the location is empty.
3. Enter the desired number. If necessary, a pause can be entered by pressing and holding 0-9, (*), or (#)
until an underscore appears in the display. The individual call list entries accept up to 5 digits. The
phone call list entries accept a combination of up to 31 digits and pauses.
4. Press and hold MENU until the display changes indicating that the number has been stored.
5. Repeat the steps above if the number stored in an entry location needs to be changed.
MM-014716-001, Rev. H
79
10.22 MOBILE DATA (EDACS AND P25 TRUNKED)
The M7300 Series mobile radios, when operating in the EDACS or P25 Trunked configuration, permit
either voice or data calls to be transmitted or received. The radio can handle only one type of call at a
time; however, selection of either data or voice is transparent to the operator. Data communications is not
supported in the conventional mode.
The radio can be connected to a Mobile Data Terminal (MDT) or to a host computer. Any RS-232
compatible device that supports the Radio Data Interface (RDI) protocol (Version 1.91 or greater) can be
connected to the mobile radio. Support for MDTs or host computers is a programmable option per radio.
Additionally, radios programmed for host computers can also be programmed for data only operation (no
voice calls transmitted or received).
NOTE
Turn power to the radio OFF before connecting or disconnecting any cables, including
the data cable. Also, turn power to the radio OFF when docking or undocking a
connected laptop computer. Failure to turn the power OFF can damage the radio,
requiring service by a Harris Corporation approved service center.
10.22.1 Displays
The following is displayed on the control unit during the various states of data mode of operation.
TX DATA
Displayed on bottom line of display when the radio is transmitting a data call.
RX DATA
Displayed on bottom line of display when the radio is receiving a data call.
DATA OFF
Displayed on top line of display when the radio is in the data disabled state.
DATA ON
Displayed for two seconds on top line of display when the radio is toggled to the data
enabled state.
10.22.2 DATA OFF Operation
The radio can be placed in the data disabled state by any of the following methods. When the data state is
disabled, the control unit displays "DATA OFF" on the top line. An ongoing data call is allowed to
complete except when an emergency is declared.
• Removing the microphone from the hookswitch (hookswitch option must be enabled by pre-
programming).
• Declaring an emergency (not to be used unless an actual emergency condition exists). Alert tone
sounds.
• Pressing OPT/OPTION (pre-programmed). Alert tone sounds.
• Selecting the function using the MENU button (pre-programmed).
10.22.3 DATA ON Operation
The data state is enabled by one of the following (depending on how it was disabled). “DATA ON” is
displayed top line of display for 2 seconds then the display returns to normal.
• Replacing the microphone into the hookswitch (going on-hook). Only valid if the “DATA OFF”
operation was entered by removing the microphone from the hookswitch (going off-hook).
• Clearing an emergency, but valid only if an emergency caused “DATA OFF” operation.
MM-014716-001, Rev. H
80
10.22.4 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 conditions
occurs, the data call is immediately terminated and the radio performs the desired function:
• PTT is activated.
• The PTT is in Public Address Mode.
• An emergency is declared by pressing the pre-programmed emergency button.
• A group or system change is made.
10.22.5 Scan Lockout Mode
Following the transmission or reception of a data call, if scan is enabled, scanning stops temporarily
(duration pre-programmed). During this time the scan LED flashes to indicate that scan is enabled but
temporarily suspended. This mode is normally exited when the pre-programmed time expires; however,
the following actions terminate the scan lockout mode before the timeout is completed.
• The CLR/CLEAR button is pressed.
• PTT is pressed.
• A group or system change is made.
• Enter phone call mode.
• Enter individual call mode.
• A new emergency assignment has been received.
• PTT is pressed in Public Address Mode.
• An emergency is declared or cleared.
• Microphone is removed from hookswitch (off-hook).
• Receiving an individual or phone call.
• Receiving an Agency, Fleet or System All Call.
• Pressing the SCAN button to turn scan ON or OFF.
10.22.6 Data Lockout Mode
The data lockout mode is a pre-programmed mode when the radio does not respond to any data channel
assignments and prevents receive data calls from interrupting voice calls. Transmit data calls are still
initiated when needed by the operator. After a pre-programmed time, the radio responds to receive data
calls; however, the following conditions clear the data lockout mode:
• The CLR/CLEAR button is pressed.
• Transmitting a data call.
• Changing a system.
• An emergency is declared.
• Pressing PTT while in Public Address Mode.
• Turning scan ON with the SCAN button.
MM-014716-001, Rev. H
81
10.23 STATUS/MESSAGE OPERATION (EDACS AND P25 TRUNKED)
Status and message operation is possible with either the Scan or System version of the M7300 Series
mobile radio unit. The following procedure is applicable for the System version. For operation with the
Scan version, the four primary keycaps must be reconfigured and pre-programmed for status/message
operation.
10.23.1 Status Operation
Status operation permits the transmission of a pre-programmed status condition to an EDACS or P25
Trunked site.
To send a status condition, press the STS button and then press one of the number buttons (0-9) to select
the pre-programmed status. If no status has been programmed for the selected number button, the radio
displays NO ENTRY and the radio sounds a low tone. A valid selection permits the status text to appear
in the display for a pre-programmed time. After the time-out expires or the MENU button has been
pressed (the MENU button overrides the time-out period), the status is selected and is transmitted to the
site or stored in the radio memory where it can be polled by the site at a future time. If the site receives
the status properly, when transmitted or polled by the site, a high-pitched tone sounds and the keylight
associated with that status remains lit. If the site does not receive the status properly, a low-pitched tone
sounds and the keylight associated with the status blinks.
If an incorrect status is selected or the incorrect number button is pressed, the status can be changed
during the pre-programmed time-out period by pressing another number button. The status selection can
also be cancelled by pressing the CLR button prior to the time-out period.
To view the currently selected status after it has been transmitted, press the STS button. If the status was
not sent successfully to the site, the text associated with the status flashes in the display.
The radio can also be pre-programmed to re-designate the keypad buttons for ST0 thru ST9 to send
status condition. In this configuration the radio status operation operates as previously described except
the STS button is not required. The keylight associated with ST0 thru ST9 indicates which status is
selected.
10.23.2 Message Operation
Message operation permits the transmission of a pre-programmed message text to an EDACS or P25
Trunked site.
To send a message, press the MSG button and then press one of the number buttons (0-9) to select the
pre-programmed message text. If no message text has been programmed for the selected number button,
the radio displays NO ENTRY and a low-pitched tone sounds. A valid selection permits the message text
to appear in the display for a pre-programmed time. After the time-out expires or the MENU button has
been pressed (the MENU button overrides the time-out period), the message text is selected and is
transmitted to the site. If the site receives the message properly when transmitted, a high pitched tone
sounds and the MSG keylight remains lit. If the site does not receive the message properly, a low-pitched
tone sounds and the MSG keylight blinks.
If an incorrect message text is selected or the incorrect number button is pressed, the message text can be
changed during the pre-programmed time-out period by pressing another number button. The message
text selection can also be cancelled by pressing the CLR button prior to the time-out period.
To view the currently selected message text after it has been transmitted, press the MSG button and then
the CLR button prior to the time-out period. If the message text was not sent successfully to the site, the
text associated with the message flashes in the display.
MM-014716-001, Rev. H
82
10.24 EDACS CONVENTIONAL P1 SCAN
This feature permits the radio user to scan a pre-programmed conventional system and channel as a
Priority 1 (P1) channel while the radio is selected for EDACS trunked system. If activity is detected on
the conventional P1 channel, the radio unmutes and remains on this conventional channel for the
programmable hang time. The radio must be pre-programmed to designate a button for scan ON/OFF
operation.
10.25 DYNAMIC REGROUP OPERATION (EDACS)
Dynamic regroup operation permits multiple talk groups (up to eight) to be added to a radio via the
Communications Systems Director (CSD). The radio must be pre-programmed to respond to regrouping.
Dynamic regrouping is not activated in a radio until an activation message is sent by the system manager.
Each radio that receives and acknowledges regrouping instructions is successfully regrouped.
Pressing and holding CLEAR/CLR for 2.5 seconds toggles the user into and out of the dynamic regroup
group set. A double beep sounds for entry or exit. The display indicates REGR_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 shows NO ENTRY. The
radio is prevented from transmitting and receiving calls in this condition except for scanned groups.
If the pre-programmed group set on the currently selected system contains an EMER/HOME group and
the radio is in dynamic regroup, the radio exits dynamic regroup and declares the emergency on the
HOME group. If no EMER/HOME group is present, the radio declares the emergency on the currently
selected dynamic regroup group.
10.26 PAGE (P25 TRUNKED ONLY)
Page sends a PING message to a radio and functions similar to Individual Call. The following procedures
describe how to initiate and complete a Page.
1. To select a previously stored individual, select PAGE from the menu followed by the ramp
control to scroll through the list of stored individuals. While in the individual call list, the MENU key
toggles the display between the call name and the unit ID number. On System model radios, the
individual’s unit ID can also be entered directly from the keypad.
2. Press the PTT button; the radio performs the necessary signaling on the control channel. On the
calling radio, line 1 shows the called individual's name if found in the list of stored individuals or ID
followed by the logical ID number of the unit being called. If the receiving radio receives the Page
and responds, both radios emits three high-pitched tones. The receiving radio also displays PAGE and
the ID of the calling radio.
10.27 SQUELCH ADJUST (CONVENTIONAL)
In the conventional mode of operation, the squelch can be re-adjusted in the MENU or from a front panel
key on the keypad that has been pre-programmed. A default value of 9, or any user level between 1 and
16, can be selected using programming software. The user can change this setting either of two ways from
the front panel keys.
NOTE
A value of 16 requires a strong signal to open squelch, a value of 2 requires a very weak
signal to open squelch, and a value of 1 is open squelch.
MM-014716-001, Rev. H
83
When the squelch adjust feature is activated, Channel Guard, T99 decode, and Scan are
disabled. When the squelch adjust feature is exited, Channel Guard, T99 decode, and
Scan are restored to their previous states.
10.27.1 Menu Selection
1. Press the MENU key and then use the ramp control to scroll through the selections until
SQUELCH is displayed. Then press MENU again.
2. The display shows SQLCH=xx, where "xx" is the value between 1 and 16.
3. Use the ramp control to scroll through the values. Then press MENU to save the new value
after the display time-out (2 seconds). The displayed value is selected and saved.
4. If the MENU or CLR key is pressed before the time-out, the menu feature exits and the squelch level
is not updated. The original value is restored.
10.27.2 Pre-Programmed Keypad Key
1. Press the pre-programmed key and the display indicates SQLCH=xx, where "xx" is the value
between 1 and 16.
2. Use the ramp control to scroll through the values. Then press MENU to save the new value
or wait for the display time-out (2 seconds). The displayed value is selected and saved.
3. If the CLR key is pressed before the time-out, the squelch level is not updated and the original value
is restored.
10.28 TYPE 99 DECODE (ANALOG CONVENTIONAL)
If the Type 99 Decode Option has been pre-programmed, individual Selective Calling is possible. The
radio can now decode individual, group, or supergroup paging calls. Two sets of Type 99 paging codes
must be pre-programmed into the radio. When the radio decodes an appropriate Type 99 code sequence,
an alert tone and visual indicator is provided to the user. The receiver then operates as a noise squelched
unit until Type 99 is reset. Type 99 decode continues to operate during this noise squelched period. The
appropriate Type 99 alert tone sounds again if it detects a valid two-tone sequence.
Type 99 operation can be reset manually or automatically (pre-programmed). Manual reset is achieved by
briefly pressing CLR, if programmed. Automatic reset, if enabled, occurs after a 30 second interval
following the most recent decode of a Type 99 tone sequence. Hookswitch (pre-programmed) can also
enable or disable Type 99 decode. The pre-programmed key light blinks when Type 99 is disabled by the
hookswitch.
Type 99 decode continues to be active while the radio's CLR button is pressed. This allows the user to
monitor calls and still be alerted when a call is directed to the user. While the user continues to press
CLR, the user hears both calls and all Type 99 tone signals. If CLR is pressed for longer than two (2)
seconds, Type 99 decode is either disabled or re-enabled depending upon its present state.
To check the Type 99 enable status, press the Scan Add/Delete ramp control. The current status of
Type 99 decode is displayed for a time-out period.
MM-014716-001, Rev. H
84
If a Horn Alert Option is installed and enabled with the Type 99 Decode Option, the radio can beep the
vehicle horn when a Type 99 call is received. This option permits alerting persons out of the vehicle when
a call is received.
Type 99 is automatically disabled when Scan is enabled.
10.28.1 Menu Selection
Press MENU and then use the ramp control to scroll through the selections until T99 ENAB is
displayed. Then press MENU to toggle the Type 99 decode state. The T99 ON or T99 OFF display
message is displayed for two seconds to show the new state.
10.28.2 Pre-Programmed Keypad Key
Press the pre-programmed key and the T99 ON or T99 OFF display message is displayed for two
seconds to show the new state.
10.29 TALK-AROUND (ANALOG CONVENTIONAL)

any, given by the manufacturer shall apply. Rechargeable batteries are excluded from this warranty but are
warranted under a separate Rechargeable Battery Warranty (ECR-7048).
B. Seller’s obligations set forth in Paragraph C below shall apply only to failures to meet the above warranties
occurring within the following periods of time from date of sale to the Buyer and are conditioned on Buyer’s
giving written notice to Seller within thirty (30) days of such occurrence:
1. for fuses and non-rechargeable batteries, operable on arrival only.

necessary repaired or replacement parts, or (iii) by replacing the failed Equipment with equivalent new or
refurbished Equipment. Any repaired or replacement part furnished hereunder shall be warranted for the
remainder of the warranty period of the Equipment in which it is installed. Where such failure cannot be
