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 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
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.
Battery Charger Safety Instructions:
Save these Instructions
1. Do not expose the charger to rain or snow.
2. Do not operate or disassemble the charger if it has received a sharp
blow, or has been dropped or damaged in any way.
3. Never alter the AC cord or plug provided with the unit. If the plug will
not fit the outlet, have the proper outlet installed by a qualified
electrician. An improper condition can result in a risk of electric
shock.
4. To reduce the risk of damage to the cord or plug, pull the plug rather
than the cord when disconnecting the charger from the AC receptacle.
5. To reduce the risk of electric shock, unplug the charger from the outlet
before attempting any maintenance or cleaning.
6. Use of an attachment not recommended or sold by Motorola may
result in a risk of fire, electric shock or personal injury.
7. Make sure the cord is located so it will not be stepped on, tripped over
or subjected to damage or stress.
8. An extension cord should not be used unless absolutely necessary.
Use of an improper extension cord could result in a risk of a fire
and/or electric shock. If an extension cord must be used, make sure
that:
• The pins on the plug of the extension cord are the same number, size
and shape as those on the plug of the charger.
• The extension cord is properly wired and in good electrical condition.
• The cord size is 18 AWG for lengths up to 100 feet, and 16 AWG for
lengths up to 150 feet.
9. The supply cord of this charger cannot be replaced. If the cord is
damaged, please refer to warranty section.
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.
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
.

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 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
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.
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 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.
