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.

Changes or modifications not expressly approved by M/A-COM, Inc. could void the user's
authority to operate the equipment.

CAUTION

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

2.1.1 Federal Communications Commission Regulations

Your M/A COM, Inc. M7200 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 M/A COM,
Inc. M7200 two-way radio has an RF exposure product label. Also, your M7200 Installation and
Operator’s Manuals include information and operating instructions required to control your RF exposure
and to satisfy compliance requirements.

3 OPERATION SAFETY RECOMMENDATIONS

3.1 TRANSMITTER HAZARDS

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:

¾ The LP gas container and its fittings.
¾ Outside filling connections shall be used for the LP gas container.
¾ 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.

10

• 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.

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 M7200 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.

MM-011553-001

• 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.

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.

4.1 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.

5 PRODUCT DESCRIPTION

The M7200 Vehicular Tactical Network provides public safety users extended connectivity with the most
advanced digital voice and data network. Extended connectivity is through two tightly coupled digital
radios that function as an in-band router between the public safety network, the mobile vehicle, and the
user's portable radio. Digital voice and data are routed between the network and the user's control head
and mobile data terminal within the vehicle or the user's portable radio when the portable radio cannot
maintain direct network connection.

The M7200 mobile radio is a state-of-the-art radio that operates seamlessly between the 800 MHz
frequency band and the 700 MHz frequency band. The M7200 is designed to meet the critical
communications demands of public service users and complies with MIL-STD-810F specifications.

The M7200 is capable of supporting multiple operating modes, including OpenSky digital operation,
EDACS or ProVoice trunked modes, P25 digital trunked mode, P25 digital conventional mode, and
conventional analog mode.

The M7200 uses Time Division Multiple Access (TDMA) technology in the OpenSky mode to allow
multiple users to share a single RF channel. In addition, a single RF channel can support simultaneous
digital voice and data communications.

The M7200 provides integrated voice and data services. Voice operation is provided using a microphone
and speaker included in the radio installation kit. For data transfers, the M7200 is constructed with an
industry-standard RS-232 interface serial port for connecting an optional laptop PC.

A PC, not included with the M7200, provides network connectivity through the standard serial
(DCE-type) interface.

The M7200 has an integrated Global Positioning System (GPS) receiver. This allows the M7200 to fully
support the Automatic Vehicular Locator (AVL) for fleet management and dispatch applications.

The OpenSky M7200 benefits from a flexible, software-based digital radio design. Features and user
profiles are software-defined and can be reprogrammed over the air. The optional over-the-air
programming feature allows communication protocols to be changed easily and added at any time.

5.1 REMOTE CONTROL HEAD OPERATION

For remote mount installations configured with a CH721 control head, all normal radio operations and
interfaces can be handled via the control head connected to the radio unit by a single twisted-pair
connection routed through a vehicle. Up to six control units may be attached to a trunk mount 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 additional
remote control heads, the following features are available from each position:

• Outgoing voice calls can be initiated. (Any control head can initiate a call but only one can talk at a

time. All other connected control heads will hear 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.

12

• Radio settings such as talk group, scan mode etc., can be controlled. (Any connected control head can

override the radio settings of other connected control heads.)

• Comfort settings, such as volume and display brightness that are applicable to the individual control

head can be adjusted and cannot be overridden by other control heads.

• An optional intercom function is available between control units. (Audio will be broadcast to ALL

connected control heads.)

5.2 INTERCOM OPERATION

The intercom option, a licensed option, allows the M7200 radio to pass audio locally between control
heads and not over the network. It gives users at multiple control heads connected to the same radio the
ability communicate with each other without transmitting over-the-air. When activated, incoming network
radio calls are still scanned and broadcast at each control head.

5.3 V-TAC OPERATION

V-TAC operation requires the V-TAC hardware configuration (RF Combiner, Vehicular Repeater Base
VRB, and Mobile Radio Unit MRU) and offers the user 4 different operating modes: Extended Coverage
for individual users (XCOV), Extended Coverage for talk groups (XCOV-TG), Scene of Incident (SOI),
and normal Mobile-Only operation. Refer to Section 6.34 for operating information on these modes.

6.2 POWER UP AND VOLUME CONTROL

6.2.1 Power Up

1. Rotate the Power/Volume Control knob clockwise to power on the radio. The display will illuminate

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. This requires a system model control head so that
the User ID and password can be entered.

3. When provisioning is complete, the radio will display the Dwell Display.

If User Login is required, the bottom line of the Dwell Display will flash the message “Pls Login.”

6.2.2 Volume Control

Turn the Power/Volume Control knob clockwise to increase the volume and counter-clockwise to
decrease the volume.

6.3 SELF-TEST

After power-up, the M7200 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.

6.4 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 6.30), requires the user to enter a User ID and password.

If encryption is enabled and authorized on the radio, the user will be 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. See the following NOTE.

• If the radio is configured for alpha-numeric passwords and the password has consecutive

duplicate numbers (“MES33” for example), enter # between
so the radio will not

• If the radio is configured for numeric-only passwords, do not enter # between duplicated

numbers.

interpret the entry as a letter (“D” in this example).

the consecutive duplicate numbers

16

5. Press the # key twice.

The User ID may be remembered from the previous log-in. (Refer to Section 6.5 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.

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

6.5 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 log-in. Manually log-off by pressing *0## (requires System Model).

If a user is logged in using encryption features, it is necessary to log-off when encryption is no longer
required.

6.6 TURNING THE RADIO OFF

To turn the radio off, rotate the Power Button/Volume Dial counter-clockwise. In multiple control head
installations, turning off the last powered-up control head will also automatically turn off the radio.

MM-011553-001

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 will automatically
restore, along with the network personality settings. In multiple control head installations, settings are
maintained for each control head position.

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 will be lost.
This can extend the time required for the radio to register with the network upon the
subsequent power-up.

6.7 MENU DISPLAY AND CONTROL AREA

Following power-up, the radio display shows the default talk group. Pressing up or down with
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 until the user presses a front panel button.

When the dwell display is active, it will change dynamically to reflect the current profile, received talk
group/caller ID (when available), or channel (when enabled).

The radio’s display is highly interactive. It responds in the top and bottom text lines as the user presses
the menu buttons (

6.10 PERSONALITY

As illustrated in Figure 6-3, 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.

6.10.1 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.

6.10.2 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.

6.13 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 6-1). 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, a single low-pitched tone will be heard from the
microphone. The key tones are not adjustable.

6.14.1 Password Entry

Password entry requires a system model control head. Password characters are encrypted on the display
using symbols to indicate the entry. The encryption symbols for each entry will appear in the display as
they are scrolled through, for example: '-' and '+'. Press the # key twice to complete the entry process.

If the password is wrong, the radio will not successfully register with the network for
wide area voice reception. The radio can still be used in single-site mode.

6.14.2 DTMF Overdial

Using the keypad on a System Model, the radio can transmit DTMF tones corresponding to
numbers/characters 0 — 9, * and # on the keypad. To overdial numbers/characters, transmit by pressing
and holding the PTT button and then, press the corresponding keys (one at a time) on the keypad.

6.15 CHANGING THE ACTIVE PROFILE

6.16 CHECKING OR CHANGING 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.

Use to 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

6.18 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 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 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.

6.18.1 Enabling Stealth Mode

1. Using , scroll through the menu until “StealthMenu” appears.

2. To immediately turn stealth mode on, press up or down with

3. To turn stealth mode off, press any button on the radio’s front panel.

6.18.2 Disabling Stealth Mode

.

Pressing any radio button other than the mic’s PTT button or the emergency button on front panel will
immediately turn stealth mode off. For example, pressing the MENU button on the front panel will turn
stealth mode off.

With stealth mode on, pressing any radio button (other than the mic’s PTT button
or the emergency button) on front panel will immediately turn stealth mode off.

6.19 ADJUSTING 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.

25

MM-011553-001

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 set side tone level:

6.21 RECEIVING AND TRANSMITTING VOICE CALLS

As soon as the radio completes the startup/log-on/provision/self-test sequence and registers on the
OpenSky network, voice calls from talk groups in the active profile will be audible.

6.21.1 Receiving a Voice Call

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

• If the dwell display is set to received talk group/caller ID/alias, the display indicates either the User

ID of the incoming caller, if available, or the talk group’s name. If the selected talk group matches the
receive talk group, caller ID/alias is displayed. Otherwise, the talk group (name) is displayed.

26

• If the dwell display is not set to received talk group, the display indicates the data appropriate to those

displays, but provides no indication as to the identity of the incoming caller.

Refer to Section 6.25 for detailed information on talk group scanning. Refer to Section 6.30 for detailed
information regarding sending and receiving encrypted calls.

6.21.2 Transmitting a Voice Call

Transmit a voice call as follows:

1. Turn the radio on.

2. If required, log-in to the network using a user ID and password. See Section 6.4 beginning on page 16

as necessary.

3. Select the desired talk group for transmitting on.

4. Depress 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 1 ½ inches from
the mouth and do not
tone to sound before speaking.

shout or whisper into it. If the call is queued by the network, wait for the grant

5. Release the PTT button when finished speaking.

Refer to Section 6.30 for detailed information regarding sending and receiving encrypted calls.

6.23 INTERCOM MODE

The optional intercom mode gives users at multiple control heads connected to the same radio the ability
communicate with each other without transmitting over-the-air. Turn intercom mode on and off using the
“INTERCOM” menu as follows:

1. Use to cycle through the available menu items until “INTERCOM” appears in the display.

2. Use

When intercom mode is turned on:

• Incoming voice calls will override intercom communications for the duration of the voice call. The

radio and associated control heads will remain in intercom mode and intercom communications will
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).

to toggle between “On” and “Off.”

• 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.

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 will not send microphone audio

anywhere.

6.24 TALK GROUP LOCK OUT

There are two ways of focusing voice communications by suppressing calls from talk groups in the
currently active profile:

No Scan. By turning scan off (selecting “No Scan” via the “ScnModeMenu”), only the selected talk group is

1.

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.

27

MM-011553-001

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.

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.

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.

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.

If the Scan Mode is “Fixed,” P1 and P2 groups CANNOT be locked out. See Section

6.25 for more information.

6.24.1 Lock Out a Talk Group

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.

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

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

6.25 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 6-6, 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.
