important note

There are no owner-serviceable parts inside the radio. All service jobs must be referred to an authorized Vertex

r

Standard Service Representative. Consult your Authorized Vertex Standard Dealer for installation of optional
accessories.

In order to maintain the specied water integrity performance, periodic maintenance is recommended.

r

Should the radio sustain a severe shock (e.g. if it is dropped), the water integrity may be compromised, requir-

r

ing service. Should this occur, contact your Authorized Vertex Standard Dealer.

Important Notice for North American Users Regarding 406 MHz Guard Band

The U.S. Coast Guard and National Oceanographic and Atmospheric Administration have requested the
cooperation of the U.S. Federal Communications Commission in preserving the integrity of the protected
frequency range 406.0 to 406.1 MHz, which is reserved for use by distress beacons. Do not attempt to pro­gram this apparatus, under any circumstances, for operation in the frequency range 406.0 - 406.1 MHz if
the apparatus is to be used in or near North America.
Warning - Frequency band 406 - 406.1 MHz is reserved for use ONLY as a distress beacon by the US
Coast Guard and NOAA. Under no circumstance should this frequency band be part of the pre pro­grammed operating frequencies of this radio.

Warning! fCC rf exposure requirements

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.

r

FCC OET Bulletin 65 Edition 97-01 (1997) Supplement C, Evaluating Compliance with FCC Guidelines for

r

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-

r

quency Electromagnetic Fields, 3 kHz to 300 GHz.

ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Measurement of Potentially Hazardous Electro-

r

magnetic Fields - RF and Microwave.

WARNING:

This radio generates RF electromagnetic energy during transmit mode. This radio is designed for and clas­sied 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 environment.

¦

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.

VX-P920 SerieS OPerating Manual

Warning! fCC rf exposure requirements

The radio must be used with a maximum operating duty cycle not exceeding 50%, in typical Push-to-

¦

Talk congurations.

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 front panel 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 congurations 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 1.5 inches (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 de-

vices 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.
