RADIO FREQUENCY ENERGY SAFETY INFORMATION
This UNIMO transceiver has been tested and complies with the standards listed below, in
regards to radio Frequency(RF) energy electromagnetic energy(EME) generated by the
transceiver
> FCC RF exposure limits for Occupational use only. RF exposure limits adopted by the FCC
are generally based on recommendations from the national council on radiation protection and
measurement, & the American National National Standards Institute.
> FCC OET Bulletin 65 Edition 97-01 Supplement C
> American National Standards Institute(C95.1-1992)
> American National Standards Institute(C95.3-1992)
WARNING
This UNIMO transceiver generates RF EME while transmitting. RF EME(Radio Frequency
Electric & Magnetic Energy)has the potential to cause slight thermal, or heating effects to any
part of your body less than the recommended distance from this radio transmitter's antenna.
RF energy exposure is determined primarily by the distance to and the power of the
transmitting device. In general, RF exposure is minimized when the lowest possible power is
used or transmission time is kept to the minimum required for consistent communications, and
the greatest distance possible from the antenna to the body is maintain.
The transceiver has been designed for and is classified for Occupational use only.
Occupational/controlled exposure limits are applicable to situations in which persons are
exposed to RF energy as a consequence of their employment, and such persons have been
made aware of the potential for exposure and can exercise control over their exposure.
This means you can use the transceiver only if you are aware of the hazards of operating a
transceiver and are familiar in ways to minimize these hazards. This transceiver is not intended
for use by the general public in uncontrolled environments.
Uncontrolled environment exposure limits are applicable to situations in which the general
public may be exposed to RF energy ,or in which the persons who are exposed as a
consequence of their employment may not be fully aware of the potential for exposure or
cannot exercise control over their exposure
The following list provides you with the information required to ensure that you are aware of RF
exposure and of how to operate this transceiver so that the FCC RF exposure limitations are
not exceeded.
> While transmitting(holding the PTT switch), always keep the antenna at least 2.5cm (1
inches) from your body or face ,as well as from any bystanders
> Do not transmit for more than 50% of the total transceiver use time; transmitting over 50%
of the total use time may exceed the limits in accordance to the FCC RF exposure
requirements. Nominal transceiver operation is 5% transmission time,5% reception time, and
90% stand-by time
> Use only the specified antenna for this transceiver; this may be either the antenna provided
with the transceiver or another antenna authorized by UNIMO.
Use only UNIMO authorized accessories (antennas, battery packs, belt clips, Speaker/Mics or
headsets etc.):
When worn on the body, always place the radio in a UNIMO recommended clip or carrying
case meant for this product. The use of other than recommended or approved body-worn
accessories may result in RF exposure levels which exceed the FCC's occupational
/controlled environment RF exposure limits.
CAUTION
To ensure that your exposure to RF EME is within the FCC limits for occupational use, you
must observe and adhere to the above points.
Electromagnetic Interference Compatibility
Electronic devices are susceptible to electromagnetic interference(EMI)if they are not
adequately shielded or designed for electromagnetic compatibility. Because this transceiver
generates RF energy, it can cause interference to such equipment.
>Turn OFF your transceiver where signs are posted to do so. Hospitals and health care
facilities use equipment that is sensitive to electromagnetic radiation.
> Turn OFF your transceiver while on board an aircraft when so instructed, Use of the
transceiver must be in accordance with airline regulations and/or crew instructions.
