Important Information on Safe and Efficient Operation
Read This Information Before Using Your Radio.
The information provided in this document supersedes the general
Two-Way Radios
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
• 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, 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

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

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.
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.
When instructed to do so, turn off your radio when onboard on 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

Safety and General UseWhile 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.
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
