Product Safety and RF Exposure for Portable Two-Way Radios
Compliance with RF Energy Exposure Standards
NOTICE: This radio is intended for use in occupational/controlled applications where users
have been made aware of the potential for exposure and can exercise control over their
exposure. This radio device is NOT authorized for general population, consumer or similar use.
BEFORE USING THIS RADIO, READ THE TRAINING MATERIAL BELOW WHICH
CONTAINS IMPORTANT OPERATING INSTRUCTIONS FOR SAFE USAGE AND RF
ENERGY AWARENESS AND CONTROL INFORMATION FOR COMPLIANCE WITH RF
ENERGY EXPOSURE LIMITS IN APPLICABLE NATIONAL AND INTERNATIONAL
STANDARDS.
Federal Communication Commission (FCC) Regulations
The FCC has established limits for safe exposure to radio frequency (RF) emissions from portable
two-way radios. The FCC requires manufacturers to demonstrate compliance with RF exposure limits
before portable two-way radios can be marketed in the U.S. When two-way radios are approved for
occupational/controlled environment exposure limits, the FCC requires users to be fully aware of, and
exercise control over, their exposure. Awareness and control of RF exposure can be accomplished by
the use of labels, or by education and training through appropriate means, such as information and
instructions in user manuals or safety booklets. Your Advanced Wireless two-way radio has an RF
exposure information label in the battery compartment. The training material below includes useful
information about RF exposure and helpful instructions on how to control your RF exposure.
Your Advanced Wireless two-way radio is designed and tested to comply with a number of national
and international standards and guidelines (listed below) regarding human exposure to RF
electromagnetic energy. In terms of measuring RF energy for compliance with FCC exposure
guidelines, your radio radiates measurable RF energy only while it is transmitting (during talking),
not when it is receiving (listening) or in standby mode.
Compliance and Control Guidelines and Operating Instructions for Portable Two-Way Radios
To control your exposure and ensure compliance with the occupational/controlled environment
exposure limits, always adhere to the following procedures:
* Transmit no more than 50% of the time. To transmit (talk), push the Push-To-Talk (PTT) button.
To receive calls, release the PTT button. Transmitting 50% of the time or less is important since the
radio generates measurable RF energy exposure only when transmitting (in terms of measuring
standards compliance).
*Hold the radio in a vertical position in front of the face with the microphone positioned at least one
inch (2.5 cm) away from the lips. Keeping the radio at the proper distance is important since RF
exposure decreases with increasing distance from the antenna.
* For body-worn operation, always use the radio with the AWC Belt-Clip Part No.: 420855203393.
AWC-approved accessories, antennas, and device combinations have been tested and comply with the
occupational/controlled environment RF exposure limits. The use of non–AWC approved accessories
may result in exposure levels that may exceed the FCC’s occupational/controlled environment RF
exposure limits.
* If you are not using a body-worn accessory and are not using the radio held in front of the face,
ensure the radio is kept a minimum of 1.3 cm from the body when transmitting. Keeping the radio at a
proper distance is important since RF exposure decreases with increasing distance from the antenna.
FCC license Information
Your Advanced Wireless Communications radio operates on communications frequencies which are
subject to FCC (Federal Communications Commission) Rules & Regulations. FCC Rules require that
all operators using Private Land Mobile radio frequencies obtain a radio license before operating their
equipment. Application for license must be made on FCC form 601, and schedules D, E, and G.
FAX: Forms can be obtained by fax from the FCC Fax-On-Demand system. Call 1-202-418-0177
from your fax machine and request document number 000600 for the form, schedules, and
instructions.
MAIL: Forms can be ordered by telephone, and will be sent to you by first class mail. Call the FCC
Forms Hotline at 1-800-418-FORM (1-800-418-3676).
INTERNET: Form 601 and instructions can be downloaded from the FCC Forms website at:
http://www.fcc.gov/Forms/Form601/601.html
Before filling out your Form 601 application Technical Data section, you must decide which
frequency (or frequencies) you will operate on. Refer to the frequency chart on page 26.
Questions? Call the FCC for license application questions at
1-888-CALL-FCC (1-888-225-5322).
If you have any questions, call Advanced Wireless Communications:

Notices to The User
This device complies with Part 15 of the FCC Rules. 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.
One or more of the following statements may be applicable:
FCC WARNING
This equipment generates or uses radio frequency energy. Changes or modifications to this equipment
may cause harmful interference unless the modifications are expressly approved in the instruction
manual. The user could lose the authority to operate this equipment if an unauthorized change or
modification is made.
INFORMATION TO THE DIGITAL DEVICE USER REQUIRED BY THE FCC
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
generate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that the
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer for technical assistance.
SAFETY INFORMATION:
Your wireless portable two-way radio has been designed using a low power transmitter.
When the PTT switch is pressed, the radio generates radio frequency (RF) electromagnetic energy
(EME). This radio is designed to comply with the FCC Report and Order
FCC 96-326 (August, 1996).
User Safety Information
PLEASE READ THIS IMPORTANT INFORMATION BEFORE USING YOUR Advanced
Wireless Communications PORTABLE TWO-WAY RADIO.
Only qualified technicians are allowed to maintain this product.
To avoid electromagnetic interference, turn off your radio in places 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 travelling on aircraft, turn off your radio when the
airline crew instructs you to do so.
When in vehicles equipped with an air bag, do not place a portable radio in the airbag
deployment area.
Turn off your radio prior to entering any area with a potentially explosive atmosphere. Do
not remove, install, or charge batteries in such areas.
To avoid possible interference with blasting operations, turn off your radio when you are
near electrical blasting caps.
Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into
contact with your skin, a minor burn may result.
Do not expose the radio to direct sunlight for long periods of time. Do not place the radio in
direct contact with any heating source.
