Safety and General Information
Important Information on Safe and Efficient Operation
Read This Information Before Using Your Radio.
The information provided in this document supersedes the general safety
information in user guides published prior to December 1, 2002.
Transmit and Receive Procedure
Your two-way radio contains a transmitter and a receiver. To control your
exposure and ensure compliance with the general population/uncontrolled
environment exposure limits, always adhere to the following procedure:
• Transmit no more than 50% of the time.
• To receive calls, release the PTT button.
• To transmit (talk), press the Push to Talk (PTT) button.
Transmitting 50% of the time, or less, is important because the radio
generates measurable RF energy exposure only when transmitting (in
terms of measuring standards compliance).
Exposure to Radio Frequency Energy
Your Motorola two-way radio complies with the following RF energy
exposure standards and guidelines:
• United States Federal communications Commission, Code of Federal
Regulations; 47CFR part 2 sub-part J.
• American National Standards Institute (ANSI)/Institute of Electrical
and Electronic Engineers (IEEE) C95. 1-1992.
• Institute of Electrical and Electronics Engineers (IEEE) C95.1-1999
Edition.
• International Commission on Non-Ionizing Radiation Protection (ICNIRP)
1998.
• Ministry of Health (Canada) Safety Code 6. Limits of Human Exposure
to Radio frequency Electromagnetic Fields in the Frequency Range
from 3 KHz to 300 GHz, 1999.
• Australian communications Authority Radio communications
(Electromagnetic Radiation—Human Exposure) Standard, 2003.
• ANATAL ANNEX to Resolution No. 303 of July 2, 2002 “Regulation of
limitation of exposure to electrical, magnetic and electromagnetic
fields in the radio frequency range between 9 KHz and 300GHz” and
“Attachment to resolution #303 from July 2, 2002”.
To assure optimal radio performance and make sure human exposure
to radio frequency electromagnetic energy is within the guidelines set
forth in the above standards, always adhere to the following procedures.
Portable Radio Operation and EME Exposure
Antenna Care
Use only the supplied or an approved replacement antenna. Unauthorized
antennas, modifications, or attachments could damage the radio and may
violate regulations.
Do NOT hold the antenna when the radio is “IN USE.” Holding the antenna
affects the effective range.
Body-Worn Operation
To maintain compliances with RF exposure guidelines, if you wear a radio
on your body when transmitting, always place the radio in a Motorola-
supplied or approved clip holder, holster, case or body harness for this
product. Use of Non-Motorola-approved accessories may exceed RF
exposure guidelines.
If you do not use one of the Motorola-supplied or approved body-worn
accessories and are not using the radio held in the normal use position,
ensure the radio and its antenna are at least 1 inch (2.5 cm) from
your body when transmitting.
Data Operation
If applicable, when using any data feature of the radio with or without
an accessory cable, position the radio and its antenna at least one
inch (2.5 cm) from the body.
Approved Accessories

www.motorola.com.
Electromagnetic Interference/Compatibility
Note: Nearly every electronic device is susceptible to electromagnetic
interference (EMI) if inadequately shielded, designed or otherwise
configured for electromagnetic compatibility. Operation is subject to the
following two conditions:
1. This device may not cause harmful interference; and
2. This device must accept any interference received, including
interference that may cause undesired operation.
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 onboard an aircraft.
Any use of a radio must be in accordance with applicable regulations per
airline crew instructions.
Medical Devices – Pacemakers
The Advanced Medical Technology Association recommends that a minimum
separation of 6 inches (15 cm) be maintained between a handheld wireless
radio and a pacemaker. These recommendations are consistent with the
independent research by and recommendations of the U.S. Food and Drug
Administration.
People with pacemakers should:
• ALWAYS keep the radio more than 6 inches (15 cm) 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 there is any reason to suspect that
interference is taking place.
Medical Devices – 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.
Medical Devices-other
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 regarding the use of radios in the area
where you drive, and always obey them. If you do use 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.
The use of a two-way radio while engaged in activities requiring concentration
may cause distraction or otherwise impair your ability to safely participate in
such activities. Always use technology safely.
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. Only radio types that are especially qualified should be used
in such areas as “Intrinsically Safe.” 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 radios.” Obey all signs and instructions.
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—like 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.
Exercise care when removing NiMH or AA batteries. Do not use sharp or
conductive tools to remove either of these batteries.
