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. This radio has been tested and complies with the FCC RF exposure limits for “Occupational Use Only”. In addition, your XRADIO radio complies with the following Standards and Guidelines with regard to RF energy and electromagnetic energy levels and evaluation of such levels for exposure to humans: ■ FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. ■ American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. ■ American National Standards Institute (C95.3-1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields– RF and Microwave. ■ The following accessories are authorized for use with this product. Use of accessories other than those (listed in the instruction) specified may result in RF exposure levels exceeding the FCC requirements for wireless RF exposure. To ensure that your expose to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines: ■ DO NOT operate the radio without a proper antenna attached, as this may damaged the radio and may also cause you to exceed FCC RF exposure limits. A proper antenna is the antenna supplied with this radio by the manufacturer or antenna specifically authorized by the manufacturer for use with this radio. ■ DO NOT transmits 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 “TX indicator” lights red. You can cause the radio to transmit by pressing the “PTT” switch. ■ ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when 4 transmitting and only use the Xradio belt-clip which is listed in instructions when attaching the radio to your belt, etc., to ensure FCC RF exposure compliance requirements are not exceeded. To provide the recipients of your transmission the best sound quality, hold the antenna at least 5 cm (2 inches) from your mouth, and slightly off to one side. 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 as-sure that this radio operates with the FCC RF exposure limits of this radio. Electromagnetic Interference/Compatibility During transmissions, your XRADIO 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, aircraft, and blasting sites. Occupational/Controlled Use The radio transmitter is used in situations in which persons are exposed as consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. OPERATING NOTES ■ When transmitting with a portable radio, hold the radio in a vertical position with its microphone 5 to 10 cm (2 to 4 inches) away from your mouth. Keep the antenna at least 2.5 cm (1 inch) from your head and body. ■ If you wear a portable two-way radio on your body, ensure that the antenna is at least 2.5 centimeters (1 inch) from your body when transmitting. PRECAUTIONS WARNING! NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the body, especially the face or eyes, while transmitting. The transceiver will perform best if the microphone is 5 to 10 cm (2 to 4 inches) away from the lips and the transceiver is vertical. WARNING! NEVER operate the transceiver with a headset or other audio accessories at high volume levels. CAUTION! NEVER short the terminals of the battery pack. NEVER connect the transceiver to a power source other than the Battery listed below Such a connection will ruin the transceiver. DO NOT push the PTT when not actually desiring to transmit. 5 AV O I …

August 13, 2009 Federal Communications Commission Equipment Authorization Branch 7435 Oakland Mills Road Columbia, MD 21046 Cover letter FCC ID : VSOXR-150 Gentlemen: 1. Yeonhwa M Tech requires the Part 90 FCC grant list frequencies outside of Part 90 assignments because state and local government users specify operation outside of Part 90 so that they can interoperate with Federal agencies. The issue being that user’s that are not under NTIA frequency coordination must use radios that have FCC approval. 2. This handheld transceiver that operated using frequency modulation(FM) incorporating traditional simplex transmission protocol (50%) duty and may be marketed to and used by employees for occupational operations, such as Federal and Public Safety agencies, e.g. police, fire and emergency medical, etc. Sincerely, Hwan-Dae Kim / Chief Engineer Yeonhwa M Tech Co.,Ltd. 3F, Yukyong B/D, 544-6, Gasan-dong, Geumcheon-gu, Seoul, Korea 153-803

Box 370 Newberry, Florida 32669 Subject: FCC ID justification letter for expanded frequency range 136- 174 MHz Gentlemen; The XR-150 Portable radio was designed to operate in the frequency bands 136-174 MHz To aid equipment authorization in other countries that accept the United States FCC Grant for Certification, Yeonhwa M Tech is requesting that the FCC list the frequencies 136-174 MHz under FCC Rule Parts 90 on the FCC Grant. For the FCC’s Rule Parts 90 applications, this radio is used in systems by Federal and Public Safety agencies including Police, Fire, and Emergency Medical Services, etc. as indicated in the table below. Frequencu Range (MHz) Part 90 Feds Grant Notes 136-150.8 X EF, BE 163.5-173.4 X X EF, BE 173.4-174 X EF, BE Equipment programming is the responsibility of Authorized Service Personnel. In addition, the radio complies with 47 CFR Part 90.203(e), in that the operator cannot directly program the transmit frequencies using the normally accessible external controls. Per the FCC’s KDB634817 guidance, “as an alternative to listing the exact frequencies, we acknowledge that it’s a violation of the FCC Rules if this device operates on unauthorized frequencies.
