microphone and earphone, etc.) from the other makers, which can cause to make a
defect on battery and a malfunction or a defect on the Radio.
Don’t disassemble or reorganize the Radio. The disassembly or reorganization will be
causes of defect or malfunction and it will be impossible to make repair afterward.
Also, a punishment can be made by law.
Don’t use the other frequency except for the permitted frequency in order not to be
punished by law.
• Don’t give an excessive shock to the Radio.
• Don’t place the Radio where the direct sunlight and/or the high temperature occurs.
• If the Radio is placed for a long time in car in summer, the hot temperature in the car
may cause an explosion of battery.
• Don’t make a damage to the battery by a sharp substance and/or an excessive shock.
7.2 Influences to the operations of Radio or other Equipments
The Radio emits a strong electronic wave, which may have an effect on the operation of other
equipments and also, can be influenced by the other devices.

in a pocket or a bag.
• When using an earphone, please don’t listen to the sound at a high level. The high
sound may have a bad effect on your ear.
• After setting the volume of the Radio at a low level, please adjust the volume step by
step to the level you want. A sudden high sound may give a bad damage to the ear or
the heart.
• Please don’t remove or replace or charge or discharge the battery at a dangerous area,
since it may cause an explosion or a fire by an electrical spark.
• At the area where an electromagnetic force can be made, please make sure to turn off
the power of the Radio.

Acknowledging Special Precautions and the FCC Notice Cautions.
Modifications not expressly approved by the party responsible for compliance could void the user's authority
to operate the equipment.
FCC compliance Information
This device complies with part 15 of FCC Rules.
Operation is subject to the following two conditions: 1. This device may not cause harmful interference, and
2. This device must accept any interference received. Including interference that may cause undesired
operation.
Information to User
This equipment has been tested and found to comply with the limits for a Class B digital device, Pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation.
This equipment generates, uses and can radiate radio Frequency
energy and, if not installed and used in accordance with th einstruction, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, whic h can
be determined by turning the equipment off and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
Reorient or relocate the receiving antenna.
> Increase the separation between the equipment and receiver
> Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

RADIO FREQUENCY ENERGY SAFETY INFORMATION
This YEONHWA M TECH 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 YEONHWA M TECH 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 bystander
> 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 YEONHWA M TECH.
Use only YEONHWA M TECH
authorized accessories (antennas, battery packs, belt clips, Speaker/Mics or headsets etc.): When worn on
the body, always place the radio in a YEONHWA M TECH recommended clip or carrying case meant for this
27
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.
