Electromagnetic Interference/Compatibility - Retevis RT618 Manual Del Usuario

can possibly cause interference with other devices or
systems. To avoid such interference, turn off the radio in
areas where signs are posted to do so.
• DO NOT operate the transmitter in areas that are sensitive
to electromagnetic radiation such as hospitals, aircraft, and
blasting sites.
• Portable Device, this transmitter may operate with the
antenna(s) documented in this filing in Push-to-Talk and
body-worn configurations. RF exposure compliance is limited
to the specific belt-clip and accessory configurations as
documented in this filing and the separation distance between
user and the device or its antenna shall be at least 2.5 cm.
• Mobile Device, during operation, the separation distance
between user and the antenna subjects to actual regulations,
this separation distance will ensure that there is sufficient
distance from a properly installed externally-mounted antenna
to satisfy the RF exposure requirements.
• Occupational/Controlled Radio, this radio is designed for
and classified as "Occupational/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; NOT intended for use in a
General population/uncontrolled environment.
• General population/uncontrolled Radio, this radio is
designed for and classified as "General
population/uncontrolled Use".
RF Exposure Compliance and Control Guidelines
and Operating Instructions
To control your exposure and ensure compliance with the
occupational/controlled environment exposure limits, always
adhere to the following procedures.
Guidelines:
•User awareness instructions should accompany the device
when transferred to other users.
•Do not use this device if the operational requirements
described herein are not met.

Operating Instructions:
• Transmit no more than the rated duty factor of 50% of the
time. To Transmit (Talk), push the Push to Talk (PTT) button.
To receive calls (listen), release the 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 for standards compliance.
• Transmit only when people outside the vehicle are at least
the recommended minimum lateral distance away from a
properly installed according to installation 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 RF
exposure limits.
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.
