Hand-Held Mode; Electromagnetic Interference/Compatibility - Retevis RT41 User Manual

instructions, externally mounted antenna.
• When operating in front of the face, worn on the body, always place
the radio in a Retevis approved clip, holder, holster, case, or body
harness for this product. Using approved body-worn accessories is
important because the use of Non-Retevis approved accessories may
result in exposure levels, which exceed the IEEE/ICNIRP occupational
/controlled environment RF exposure limits.
• If you are not using a body worn accessory and are not using the
radio in the intended use position, in front of the face or at the body in
the PTT mode or alongside of the head in the phone mode, then
ensure the antenna and the radio are kept 2.5 cm (one inch) from the
body when transmitting. Keeping the radio at a proper distance is
important because RF exposures decrease with increasing distance
from the antenna.

Hand-held Mode

• Hold the radio in a vertical position with the microphone
(and other parts of the radio including the antenna)
at least 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.
WARNING
• Turn off your radio when you are in a potentially hazardous
environments: 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
WARNING
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 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).
