WARNING! FCC RF EXPOSURE REQUIREMENTS
FCC ID: 10334821/IC ID: 511B-10334821
Vertex Standard Co., Ltd.
This Radio has been tested and complies with the Federal Communications Commission (FCC) RF exposure
limits for Occupational Use/Controlled exposure environment. In addition, it complies with the following
Standards and Guidelines:
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 Fre-
quency 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:
To ensure that your expose to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines:
This radio is NOT approved for use by the general population in an uncontrolled exposure environ-
ment. This radio is restricted to occupational use, work related operations only where the radio operator must have the knowledge to control his or her RF exposure conditions.
When transmitting, hold the radio in a vertical position with its microphone 2 inches (5 cm) away
from your mouth and keep the antenna at least 2 inches (5 cm) away from your head and body.

WARNING! FCC RF EXPOSURE REQUIREMENTS
FCC ID: 10334821/IC ID: 511B-10334821
Vertex Standard Co., Ltd.
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 accessory:
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.

Battery Pack Installation and Removal
To install the battery, hold the transceiver with
your left hand, so your palm is over the speaker
and your thumb is on the top of the belt clip. Carefully mate the battery’s four insertion slots with
their corresponding alignment tabs on the transceiver case, while tilting the Belt Clip outward.
Proper alignment occurs with the battery pack
offset about 1/2 inch from the top edge of the battery compartment.
Guide the pack on to the tabs with a slight inward
pressure, then slide the battery pack upward, until it locks in place with a “Click.”
Tilt the Belt Clip
Insert the Battery Pack
To remove the battery, turn the radio off and re-
move any protective cases. Slide the Battery Pack
Latch on the bottom of the radio toward the front
panel while sliding the battery down about 1/2
inch. Then lift the battery out from the radio while
unfolding the Belt Clip.
Do not attempt to open any of the rechargeable Lithium-Ion packs, as they could ex-
plode if accidentally short-circuited.
Low Battery Indication
As the battery discharges during use, the voltage
gradually becomes lower. When the battery voltage
becomes to low, substitute a freshly charged battery
and recharge the depleted pack. The LED indicator
on the top of the radio will blink red when the battery voltage is low.
Caution
Danger of explosion if battery is replaced with
an incorrect battery. Replace only with the same
or equivalent type.
