Hand-held Mode
• Hold the radio in a vertical position with the microphone (and other
parts of the radio including the antenna) atleast 2.5 cm (one inch)
away from the nose or lips. The antenna should be kept away from
the eyes. Keeping the radio at a proper distance is important as RF
exposure decreases with increasing distance from the antenna.
Phone Mode
• When placing or receiving a phone call, hold your radio product as you would a
wireless telephone. Speak directly into the microphone.

Electromagnetic Interference/Compatibility

Note: Nearly every electronic device is susceptible to electromagnetic interference
(EMI) if inadequately shielded, designed, or otherwise configured for
electromagnetic compatibility.
Avoid Burns
Small Parts. Not for children under 3 years.
Turn off your radio power in the following conditions:
• Turn off your radio before removing (installing) a battery or accessory or
when charging battery.
• Turn off your radio when you are in a potentially hazardous environments:
WARNING
Near electrical blasting caps, in a blasting area, in explosive atmospheres
(inflammable gas, dust particles, metallic powders, grain powders, etc.).
• Turn off your radio while taking on fuel or while parked at gasoline service
stations.
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 (Pacemakers, Hearing Aids and
Other Medical Devices) may be using equipment that is sensitive to
external RF energy.
• Turn off your radio when on board an aircraft. Any use of a radio must be
in accordance with applicable regulations per airline crew instructions.
Note:
- Pacemakers
Defibrillators or other Implanted Medical Devices Persons with pacemakers,
Implantable Cardioverter-Defibrillators (ICDs) or other active implantable
medical devices (AIMD) should:
• ALWAYS keep the radio more than 15cm from their pacemaker when the
9
radio is turned on.
• Consult with their physicians regarding the potential risk of interference
from radio frequency transmitters, such as portable radios (poorly
shielded medical devices may be more susceptible to interference).
• Turn the radio OFF immediately if they have any reason to suspect that
interference is taking place.
• Do not carry the radio in a chest pocket or near the implantation site,
and carry or use the radio on the opposite side of their body from the
implantable device to minimize the potential for interference.
- 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.

Protect your hearing:

• Use the lowest volume necessary to do your job.
• Turn up the volume only if you are in noisy surroundings.
• Turn down the volume before adding headset or earpiece.
WARNING
• Limit the amount of time you use headsets or earpieces at high volume.
• When using the radio without a headset or earpiece, do not place the
radio's speaker directly against your ear.
Note:
Exposure to loud noises from any source for extended periods of time
may temporarily or permanently affect your hearing. The louder the radio's
volume, the less time is required before your hearing could be affected.
Hearing damage from loud noise is sometimes undetectable at first and
can have a cumulative effect.
Avoid Burns
Antennas
• Do not use any portable radio that has a damaged antenna. If a damag-
WARNING
ed antenna comes into contact with the skin when the radio is in use, a
minor burn can result.
Batteries (If appropriate)
• When the conductive material such as jewelry, keys or chains touch
exposed terminals of the batteries, may complete an electrical circuit
(short circuit the battery) and become hot to cause bodily injury such as
