Electromagnetic Interference - DeWalt DXDMR500 User Manual

• Limit the amount of time you use headsets or earpiece at high volume
levels.
• When using the radio without a headset or earpiece, do not place the
radio's speaker directly against your ear.
2. Observe all signs and instructions that require an electrical device or RF
radio product to be switched off in designated areas, such as gas/refueling
stations, hospitals, blasting areas, potentially explosive atmospheres, or
aircraft.
3. If you experience a skin irritation after using this product, discontinue use
and seek medical attention.
4. If the product or charger: overheats; has a damaged cord or plug; has been
dropped or damaged; has been dropped into water, disconnect any charger
from its power supply, discontinue use of the product.
5. Never use your radio outdoors during a thunderstorm. Keep the radio out of
reach of babies and young children.
6. NEVER hold the radio so that the antenna is very close to, or touching
exposed parts of the body, especially the face or eyes, while transmitting.
The radio will perform best if the microphone is around 2 inches (5 cm)
away from the lips and the radio is vertical.

Electromagnetic Interference

Nearly every electronic device is susceptible to electromagnetic interference
(EMI) if inadequately shielded, designed, or otherwise con gured for
electromagnetic compatibility. Turn off your radio in any facility where posted
notices instruct you to do so. These facilities may include hospitals or health
care facilities that may be using equipment that is sensitive to external RF
energy.
• When instructed to do so, turn off your radios when on board an aircraft. Any
use of a RF device must be in accordance with applicable laws, regulations
and airline crew instructions.
• Some radios may interfere with some hearing aids. In the event of such
interference, you may want to consult your hearing aid manufacturer or
physician to discuss alternatives.
• 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
doctor or physician may be able to assist you in obtaining this information.

CAUTION:
This device complies with Part 15 of the FCC/RSS-119 of the IC Rules. Operation is
subject to the condition that this device does not cause harmful interference.
Your D WALT radio generates RF electromagnetic energy during transmit mode. This
E
radio is designed for and classified as "Occupational Use Only"/"Controlled Use
Only", meaning it must be used only during the course of employment by individuals
aware of the hazards, and the ways to minimize such hazards.
This radio is NOT intended for use by the "General Population" in an uncontrolled
environment.
Important: Your D
WALT radio has been tested and complies with the FCC/IC RF
E
exposure limits for "Occupational Use Only"/ "Controlled Use Only". In addition, your
radio complies with the following Standards and Guidelines with regard to RF energy
and electromagnetic energy levels and evaluation of such levels for exposure to
humans:
• FCC OET Bulletin 65 Supplement C, Edition 01-01, Evaluating Compliance with FCC
Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.
• IC RSS-102 Issue 2 Radio Frequency Exposure Compliance of Radiocommunication
Apparatus.
• American National Standards Institute (C95.1 - 2005), IEEE Standard for Safety
Levels with Respect to Human Exposure to Radio Frequency Electromagnetic
Fields, 3 kHz to 300 GHz.
• American National Standards Institute (C95.3 - 2002), IEEE Recommended
Practice for the Measurement of Potentially Hazardous Electromagnetic Fields - RF
and Microwave.
• IEEE Standard 1528-2003.
To ensure that your exposure to RF electromagnetic energy is within the FCC/IC
allowable limits for "Occupational Use Only"/ "Controlled Use Only", always adhere to
the following guidelines:
• DO NOT operate the radio without a proper 50 Ohm antenna attached, as this may
damage the radio and may also cause you to exceed FCC/IC RF exposure limits. A
proper antenna is the antenna supplied with this radio by the manufacturer or an
antenna specifically authorized by the manufacturer for use with this radio.
• DO NOT transmit for more than 50% of total radio use time ("50% duty cycle").
Transmitting more than 50% of the time can cause FCC/IC RF exposure
compliance requirements to be exceeded. The radio is transmitting when the "TX
indicator" light is red. You will cause the radio to transmit by pressing the "PTT"
switch.
• ALWAYS use D WALT authorized accessories (antennas, batteries, belt clips,
E
speaker/microphones, etc). Use of unauthorized accessories can cause the FCC/IC
RF exposure compliance requirements to be exceeded.
• ALWAYS keep the antenna at least 1 inch (2.5 cm) away from your head and body
when transmitting and only use the D WALT belt-clips, listed in this user manual,
