FCC 96-326, Guidelines for Evaluating the Environmental Effects of Radio-Frequency Radiation.
FCC OET Bulletin 65 Edition 97-01 (1997) Supplement C, Evaluating Compliance with FCC Guidelines for
Human Exposure to Radio Frequency Electromagnetic Fields.
ANSI/IEEE C95.1-1992, IEEE Standard for Safety Levels with Respect to Human Exposure to Radio
Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Measurement of Potentially Hazardous Elec-
tromagnetic Fields - RF and Microwave.
WARNING:
This radio generates RF electromagnetic energy during transmit mode. This radio is designed for and
classified as Occupational 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. This radio is not intended for use
by the General Population in an uncontrolled environment.
CAUTION:

Vertex Standard Co., Ltd.
FCC ID: K6610334620/IC ID: 511B-10334620
The radio must be used with a maximum operating duty cycle not exceeding 50%, in typical
Push-to-Talk configurations.
DO NOT transmit for more than 50% of total radio use time (50% duty cycle). Transmitting
more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded.
The radio is transmitting when the red LED on the top of the radio is illuminated. You can cause
the radio to transmit by pressing the P-T-T button.
SAR compliance for body-worn use was only demonstrated for the specific belt-clip Part Number
(CLIP-920). Other body-worn accessories or configurations may NOT comply with the FCC RF
exposure requirements and should be avoided.
DO NOT transmit when the radio is used in Body Worn configuration with the following acces-
sory: belt-clip.
It must be used ONLY for (1) there is 4 cm distance from the body during transmitting, (2)
monitoring purposes, using the speaker only and (3) for carrying purposes.
Always use Vertex Standard authorized accessories.
The information listed above provides the user with the information needed to make him or her
aware of RF exposure, and what to do to assure that this radio operates with the FCC RF exposure limits of this radio.
Electromagnetic Interference/Compatibility
During transmissions, this radio generates RF energy that 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, health care facilities, aircraft, and blasting sites.
