2/16FCC License requiredThis Transceiver is intended for use in the operation of commercialactivities.The Federal Communications commission (FCC) requires you to belicensed before you operate this transceiver. Unless you are alreadylicensed to operate on one of the preset fequencies, you must applyfor a frequency through the PCIA (Personal Communication IndustryAssociation), a non-profit organization that assigns frequenciesnationwide to help prevent conflicts between different businessesusing transceivers in the same area. For more information aboutgetting a license, contact the PCIA at 800-759-0300, extension 3068(in Virginia 703-739-0300, extension 3068)For other questions concerning the license application, contact theFCC at 717-337-1212, or wirte: FCCP.O.Box 1040Gettysburg, PA 17325For the latest FCC application form and instructions, call the FCC’sfax-on-demand service at 1-202-418-0177 from a fax machine and requestone or more of the following documents:All forms and instructions ……………………000600Form 600 instructions only……………………006001Main Form 600 only……………………………006002Form 600 schedules only………………………006003If you do not have a fax machine, you can call the Government FormsDistribution Center at 1-800-418-FORM and request that the form andinstructions be mailed to you.FCC Part 95 RulesYou must be familiar with Part 95 of FCC Rules before you operate yourtransceiver. The operation instructions in this manual conform to Part95, but do not cover all items in Part 95.Overall, Part 95 states that:! You must have a valid license before you use the transceiver.! As licensee, you are responsible for proper operation of alltransceivers operating under your license’s authority.! You can let unlicensed persons operate transmitter, as long as youtake precautions to prevent unauthorized transmissions.! You must use this transceiver only for commercial use of yourbusiness, and only when other commercial channels (such as thetelephone) are either not available or not practical.! You must always yield the operating frequency to communications thatinvolve the safety of life or property.! You must take reasonable precautions to prevent harmful interferenceto other services operating on the same frequency.! You must not transmit program material of any kind used inconnection with commercial broadcasting.! You must not provide a service that is normally handles by telephoneor telegraph unless such broadcasts involve the safety of life andproperty or in emergencies such as an earthquake, hurricane, flood or
3/16a similar disaster where normal communications channels are disrupted.! During each transmissions or exchange of transmissions, you mustidentify your station with the call sign issued to you by the FCC, oronce each 15 minutes during periods of continuous operation.! You must keep a written record of any maintenance or modificationsmade to the transceiver, and you must make this record available forinspection upon demand by the FCC.Violating any of the provisions of Part 95 can result in fines and/orconfiscation of equipment.Your transceiver might cause TV or Radio interference even when it isoperating properly. To determine whether your transceiver is causingthe interference, turn off your transceiver. If the interference goesaway, your transceiver us causing it. Try to eliminate theinterference by:! Moving your transceiver away from the receiver! Contacting your local RadioShack store for helpIf you cannot eliminate the interference, the FCC requires that youstop using your transceiver.Before you operate the transceiver, you must obtain your license. Itis illegal to transmit without the appropriate license, which you canget by submitting a completed FCC Form 600 to the FCC (or through thePCIA). Furthermore, your are required to understand Part 95 of the FCCRules and Regulations prior to operating your transceiver. It is theuser’s responsibility to see that this unit is operating at all timesin accordance with the FCC Rules and Regulations.Safety InformationYour Handheld Radio generates RF electromagnetic energy during transmit mode. This radio isdesigned for and classified as “ Occupational Use Only”, meaning it must be used only during thecourse 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.This radio has been tested and complies with the FCC RF exposure limits for “Occupational Use Only.”In addition, your Handheld radio complies with the following Standards and Guidelines with regard to RFenergy and electromagneticenergy levels and evaluation of such levels for exposure to humans:• FCC OET Bulletin 65 Edition 01-01 Supplement C, Evaluating Compliance with FCC Guidelines forHuman Exposure to Radio Frequency Electromagnetic Fields.• American National Standards Institute (ANSI) (C95.1—1992), IEEE Standard for Safety Levels withRespect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.• American National Standards Institute (C95.3—1999), IEEE Recommended Practice for theMeasurements of Potentially Hazardous Electromagnetic Fields — RF and Microwave.To ensure that your exposure to RF electromagnetic energy is within the FCC allowable limits foroccupational use, always adhere to the following guidelines:DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may also
4/16cause you to exceed FCC RF exposure limits. A proper antenna is the antenna supplied with the radio bythe manufacturer or an antenna specifically authorized by the manufacturer for use with this radio.For body worn operation, this handheld radio has been tested and meets the FCC RF exposure guidelineswhen used with the TTI or authorized OEM dealers accessories supplied or designated for this product.Use of other accessories may not ensure compliance with FCC RF exposure guideline.To provide the recipients of your transmission the best sound quality, hold the antenna at least 2.5 cm (1inch) from your mouth.USE ONLY authorized accessories (speaker/microphones, handstraps, etc.) with your radio. Use ofunauthorized accessories can cause the FCC RF exposure compliance requirements to be exceeded.The information listed above provides the user with the information needed to make him or heraware of RF exposure, and what to do to assure that this radio operates within the FCC RFexposure limits of the radio.ELECTROMAGNETIC INTERFERENCE/COMPATIBILITYDuring transmissions, your handheld radio generates RF energy that can possibly cause interference withother devices or systems. To avoid such interference, turn off the radio in areas where signs are posted todo so.DO NOT operate the transmitter in areas sensitive to electromagnetic radiation, such as hospitals,aircraft, and blasting sites.CAUTIONS:• NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the bodywhile transmitting. The transceiver will perform best if the microphone is 2.5– 5 cm (1 to 2 inches) awayfrom the mouth and the transceiver is vertical.• For body worn operation, this handheld radio has been tested and meets the FCC RF exposureguidelines when used with the TTI or authorized OEM dealers accessories supplied or designated for thisproduct. Use of other accessories may not ensure compliance with FCC RF exposure guideline.• DO NOT push the PTT when not actually desiring to transmit.
