IMPORTANT INFORMATION ON SAFE AND EFFICIENT OPERATION
READ THIS INFORMATION BEFORE USING YOUR RADIO
Radio Frequency
(RF) Operational
Characteristics
To transmit (talk) you must push the Push-To-Talk button;
to receive (listen) you must release the Push-To-Talk button.
When the radio is transmitting, it generates radio frequency (RF)
energy; when it is receiving, or when it is off, it does not generate RF
energy.
Radio Operation
and EME Exposure
Your Motorola radio is designed to comply with the following national
and international standards and guidelines regarding exposure of
human beings to radio frequency electromagnetic energy (EME):
• United States Federal Communications Commission, Code of
Federal Regulations; 47 CFR part 2 sub-part J
• American National Standards Institute (ANSI) / Institute of
Electrical and Electronic Engineers (IEEE) C95. 1-1992
• Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999
Edition
• National Council on Radiation Protection and Measurements
(NCRP) of the United States, Report 86, 1986
• International Commission on Non-Ionizing Radiation Protection
(ICNIRP) 1998
• Ministry of Health (Canada) Safety Code 6. Limits of Human
Exposure to Radiofrequency Electromagnetic Fields in the
Frequency Range from 3 kHz to 300 GHz, 1999
• Australian Communications Authority Radiocommunications
(Electromagnetic Radiation - Human Exposure) Standard 1999
(applicable to wireless phones only)
Two-way Radio
Operation
When using your radio, hold the radio in a vertical
position with the microphone one to two inches
(2.5 to 5 centimeters) away from the lips.
Body-worn Operation
To maintain compliance with FCC RF exposure guidelines, if you wear
a radio on your body when transmitting, always place the radio in a
Motorola approved clip, holder, holster, case, or body
harness for this product . Use of non-Motorola-approved
accessories may exceed FCC RF exposure guidelines. If you do not
use a Motorola approved body-worn accessory and are not
using the radio in the intended use positions along side of
the head in the phone mode or in front of the face in the
MAN WITH RADIO

Safety 3
two-way radio mode, then ensure the antenna and radio is
kept the following minimum distances from the body when
transmitting:
• Phone or Two-way radio mode: one inch (2.5 centimeters)
• Data operation using any data feature with or without an
accessory cable: one inch (2.5 centimeters)
Antenna Care
Use only the supplied or an approved replacement antenna.
Unauthorized antennas, modifications, or attachments could damage
the radio and may violate FCC regulations.
DO NOT hold the antenna when the radio is “IN USE”.
Holding the antenna affects call quality and may cause the radio to
operate at a higher power level than needed.
Approved Accessories
For a list of approved Motorola accessories, look in the appendix or
accessory section of your radio’s User Guide.
Electromagnetic
Interference/
Compatibility
NOTE: Nearly every electronic device is susceptible to
electromagnetic interference (EMI) if inadequately
shielded, designed or otherwise configured for
electromagnetic compatibility.
Facilities
To avoid electromagnetic interference and/or compatibility conflicts,
turn off your radio in any facility where posted notices instruct you to
do so. Hospitals or health care facilities may be using equipment that
is sensitive to external RF energy.
Aircraft
When instructed to do so, turn off your radio when on board an
aircraft. Any use of a radio must be in accordance with applicable
regulations per airline crew instructions.
Medical Devices
• Pacemakers
The Health Industry Manufacturers Association recommends that
a minimum separation of 6 inches (15 centimeters) be maintained
between a handheld wireless radio and a pacemaker.These
recommendations are consistent with those of the U.S. Food and
Drug Administration.
Persons with pacemakers should:
• ALWAYS keep the radio more than 6 inches (15 centimeters)
from their pacemaker when the radio is turned ON.
• not carry the radio in the breast pocket.
• use the ear opposite the pacemaker to minimize the potential
for interference.
• turn the radio OFF immediately if you have any reason to
suspect that interference is taking place.
• Hearing Aids
Some digital wireless radios may interfere with some hearing aids.
In the event of such interference, you may want to consult your
hearing aid manufacturer to discuss alternatives.

Safety 4
• Other Medical Devices
If you use any other personal medical device, consult the
manufacturer of your device to determine if it is adequately
shielded from RF energy. Your physician may be able to assist you
in obtaining this information.
Safety And General
Use While Driving
Check the laws and regulations on the use of radios in the area where
you drive, always obey them.
When using your radio while driving, please:
• Give full attention to driving and to the road.
• Use hands-free operation, if available.
• Pull off the road and park before making or answering a call if
driving conditions so require.
Operational
Warnings
For Vehicles With An Air
Bag
Do not place a portable radio in the area over an air bag or in the air
bag deployment area. Air bags inflate with great force. If a portable
radio is placed in the air bag deployment area and the air bag inflates,
the radio may be propelled with great force and cause serious injury to
occupants of the vehicle.
Potentially Explosive
Atmospheres
Turn off your radio prior to entering any area with a potentially
explosive atmosphere, unless it is a radio type especially qualified for
use in such areas as “Intrinsically Safe” (for example, Factory Mutual,
CSA, UL, or CENELEC). Do not remove, install, or charge batteries in
such areas. Sparks in a potentially explosive atmosphere can cause an
explosion or fire resulting in bodily injury or even death.
NOTE: The areas with potentially explosive atmospheres
referred to above include fueling areas such as below
decks on boats, fuel or chemical transfer or storage
facilities, areas where the air contains chemicals or
particles, such as grain, dust or metal powders, and
any other area where you would normally be advised
to turn off your vehicle engine. Areas with potentially
explosive atmospheres are often but not always
posted.
Blasting Caps And Areas
To avoid possible interference with blasting operations, turn off your
radio when you are near electrical blasting caps, in a blasting area, or
in areas posted: “Turn off two-way radio.” Obey all signs and
instructions.

Safety 5
Operational
Cautions
Antennas
Do not use any portable radio that has a damaged antenna.
If a damaged antenna comes into contact with your skin, a minor burn
can result.
Batteries
All batteries can cause property damage and/or bodily injury such as
burns if a conductive material such as jewelry, keys, or beaded chains
touch exposed terminals. The conductive material may complete an
electrical circuit (short circuit) and become quite hot. Exercise care in
handling any charged battery, particularly when placing it inside a
pocket, purse, or other container with metal objects.
Important Safety
Information:
Intrinsically Safe
Radios
FMRC Approved
Equipment
Anyone intending to use a radio in a location where hazardous
concentrations of flammable material exist (hazardous atmosphere) is
advised to become familiar with the subject of intrinsic safety and with
the National Electric Code NFPA 70 (National Fire Protection
Association) Article 500 (hazardous [classified] locations).
An Approval Guide, issued by Factory Mutual Research Corporation
(FMRC), lists manufacturers and the products approved by FMRC for
use in such locations. FMRC has also issued a voluntary approval
standard for repair service (“Class Number 3605").
FMRC Approval labels are attached to the radio to identify the unit as
being FM Approved for specified hazardous atmospheres. This label
specifies the hazardous Class/Division/Group along with the part
number of the battery that must be used. Their Approval mark is
shown below.
!
C a u t i o n
FM
APPROVED
Do not operate radio communications
equipment in a hazardous atmosphere unless
it is a type especially qualified (e.g. FMRC
Approved) for such use. An explosion or fire
may result.
Do not operate the FMRC Approved Product in
a hazardous atmosphere if it has been
physically damaged (e.g. cracked housing).
An explosion or fire may result.
Do not replace or charge batteries in a
hazardous atmosphere. Contact sparking may
occur while installing or removing batteries
and cause an explosion or fire.
!
W A R N I N G
!

Safety 6
Radios must ship from the Motorola manufacturing facility with the
hazardous atmosphere capability and FM Approval labeling. Radios
will not be “upgraded” to this capability and labeled in the field.
A modification changes the unit's hardware from its original design
configuration. Modifications can only be done by the original product
manufacturer at one of its FMRC audited manufacturing facilities.
Repair of FMRC
Approved Products
REPAIRS FOR MOTOROLA FMRC APPROVED PRODUCTS ARE THE
RESPONSIBILITY OF THE USER.
You should not repair or relabel any Motorola manufactured
communication equipment bearing the FMRC Approval label (“FMRC
Approved Product”) unless you are familiar with the current FMRC
Approval Standard for repair service (“Class Number 3605").
You may want to consider using a repair facility that operates under
3605 repair service approval.
!
W A R N I N G
!Do not replace or change accessories in a
hazardous atmosphere. Contact sparking
may occur while installing or removing
accessories and cause an explosion or fire.
Do not operate the FMRC Approved Product
unit in a hazardous location with the
accessory contacts exposed. Keep the
connector cover in place when accessories
are not used.
Turn radio off before removing or installing
a battery or accessory.
Do not disassemble the FMRC Approved
Product unit in any way that exposes the
internal electrical circuits of the unit.
Failure to use an FMRC Approved Product
unit with an FMRC Approved battery or
FMRC Approved accessories specifically
approved for that product may result in the
dangerously unsafe condition of an
unapproved radio combination being used
in a hazardous location.
Unauthorized or incorrect modification of
an FMRC Approved Product unit will negate
the Approval rating of the product.
!
W A R N I N G
!
Incorrect repair or relabeling of any FMRC
Approved Product unit could adversely
affect the Approval rating of the unit.
Use of a radio that is not intrinsically safe in
a hazardous atmosphere could result in
serious injury or death.
!
W A R N I N G

Safety 7
FMRC's Approval Standard Class Number 3605 is subject to change at
any time without notice to you, so you may want to obtain a current
copy of 3605 from FMRC. Per the December, 1994 publication of 3605,
some key definitions and service requirements are as follows:
Repair
A repair constitutes something done internally to the unit that would
bring it back to its original condition Approved by FMRC. A repair
should be done in an FMRC Approved facility.
Items not considered as repairs are those in which an action is
performed on a unit which does not require the outer casing of the
unit to be opened in a manner which exposes the internal electrical
circuits of the unit. You do not have to be an FMRC Approved Repair
Facility to perform these actions.
Relabeling
The repair facility shall have a method by which the replacement of
FMRC Approval labels are controlled to ensure that any relabeling is
limited to units that were originally shipped from the Manufacturer
with an FM Approval label in place. FMRC Approval labels shall not be
stocked by the repair facility. An FMRC Approval label shall be ordered
from the original manufacturer as needed to repair a specific unit.
Replacement labels may be obtained and applied by the repair facility
providing satisfactory evidence that the unit being relabeled was
originally an FMRC Approved unit. Verification may include, but is
not limited to: a unit with a damaged Approval label, a unit with a
defective housing displaying an Approval label, or a customer invoice
indicating the serial number of the unit and purchase of an FMRC
Approved model.
Do Not Substitute
Options or Accessories
The communications equipment package that Motorola submits to
FMRC for testing and approval is tested as a system that consists of the
communications unit itself and the battery, antenna and other
options or accessories that make up the rest of the package to be
approved. This approved package must be strictly observed and there
must be no substitution of items, even if the substitute you wanted to
consider appears as an approved accessory elsewhere in the Guide for
some other communications equipment unit. Approved
configurations are listed by FMRC Approved Product in the annual
Approval Guide published by FMRC. That guide, and the Approval
Standard Class Number 3605 document, can be ordered from the
following address.

Model Charts
Model Programming,
Flashing, and Cloning
vii
Four model charts cover the three families of radios discussed in
this publication:
• Conventional Systems Radios, HT 1000
• Conventional Systems Radios, JT 1000 and MT 2000
• Private Systems Radios
• Shared Systems Radios
Each model chart lists the model number and its description,
and the three main radio components: the transceiver board, the
controller board, and the front cover. A single model may be
built using alternate controller boards and alternate transceiver
boards. The model charts will list all alternate controllers and all
alternate transceivers for any one particular model. Other model
components are referenced in electrical parts lists and exploded
view parts lists located toward the rear of the manual.
To determine which controller and transceiver is in a radio, that
radio must be opened and physically examined. Identification
kit number labels are attached to the controller board and to the
transceiver board.

General Description
All HT 1000, JT 1000, MT 2000, MTS 2000, and MTX Series
Radios covered in this manual are clonable. The JT 1000 Model
Radios are also front-panel programmable, and the MTS 2000
Series Radios are “flashable.” The following cloning information
applies only to HT 1000 Model Radios.
HT 1000 Model Radios:
• VHF DN models cannot be cloned to AN, BN, or CN models.
• Any DN model can be cloned from like CN or DN models.
• Prior to cloning any AN or BN model into a like CN or DN
model, a code plug fix must be performed on the AN or BN
model. Failure to do so could seriously degrade the scan and
battery-saver capabilities of the CN or DN model radio. For
code plug-fix information, order Service Repair Notice,
SRN-1218.
Note: Cloning any AN model into a like CN or DN model will
remove the TEST MODE capability.
