R74TC-980U1TWO-WAY RADIO

This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must except any interference received, including interference that may cause undesired operation. SAFETY TRAINING INFORMATION Your HYT 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, Warning 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 HYT 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 Potential y Hazardous Electromagnetic Fields— RF and Microwave. To ensure that your exposure to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following CAUTION guidelines: • DO NOT operate the radio without a proper antenna attached, as this may damage 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 an antenna specifically authorized by the manufacturer for use with this radio. • 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 “TX indicator” lights red. You can cause the radio to transmit by pressing the “PTT” switch. • ALWAYS use HYT authorized accessories (antennas, batteries, belt clips, speaker/mics, etc). Use of unauthorized accessories can cause the FCC RF exposure compliance requirements to be exceeded. Body-worn operations are restricted to belt-clips, holsters or similar accessories that have no metallic component in the assembly and that provide at least 1.5 cm separation between the device, including its antenna, and the user's body. To provide the recipients of your transmission the best sound quality, hold the antenna at least 5 cm (2 inches) from 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 assure that this radio operates within the FCC RF exposure limits of this radio. Electromagnetic Interference/Compatibility During transmissions, your HYT 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. FOREWORD Thank you for purchasing the HYT transceiver. READ ALL INSTRUCTIONS carefully and completely before using the transceiver. SAVE THIS INSTRUCTION MANUAL–This instruction manual contains important operating instructions for the transceiver. INSTALLATION NOTES • Body-worn operations are restricted to belt-clips, holsters or similar accessories that have no metallic component in the assembly and that provide at least 1.5 cm separation between the device, including its antenna, and the user's body • If you wear a portable two-way radio on your body, ensure that the antenna is at least 2.5 centimeters (1 in.) from your body when transmitting. IMPORTANT RF CAUTION! 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 2 to 4 in. (5 to 10 cm) away from the lips and the transceiver is vertical. RF CAUTION! NEVER operate the transceiver with a headset or other audio accessories at high volume levels. RF CAUTION! NEVER short the terminals of the battery pack. DO NOT push the PTT when not actually desiring to transmit. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below +14°F (–10°C) or above +122°F (+50°C). The basic operations, transmission and reception of the transceiver, are guaranteed within the specified operating temperature range (depending on version). However, the LCD display may not be operate correctly, or show an indication in the case of long hours of operation, or after being placed in extremely cold areas. DO NOT modify the transceiver for any reason. KEEP the transceiver from the heavy rain, and never immerse it in the water. The transceiver construction is water resistant, not waterproof. The use of non HYT battery packs/chargers may impair transceiver performance and invalidate the warranty.

Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 Gentlemen: This letter is to comply with Sections 0.457 and 0.459 pertaining to confidential material. Shenzhen HYT Science & Technology Co., Ltd. would like the following documents regarding this submission for FCC ID: R74TC-980U1 and IC: 5465A-TC980U1 to be kept confidential. 1. Circuit Diagram 2. Block Diagram 3. Circuit Description The above material contains trade secrets or technical data, which would customarily be guarded from competitors. We do not want these documents to be accessible to the general public. Sincerely yours Shenzhen HYT Science & Technology Co., Ltd. Xiong Lei / Sales Manager

Jan.09, 2008 Timco Engineering, Inc. 849 NW State Road 45 P.O. Box 370 Newberry, Florida 32669 Subject: FCC ID: R74TC-980U1 justification letter for expanded frequency range 400-470 MHz Gentlemen; You have asked Shenzhen HYT Science & Technology Co., Ltd. for justification to have the freq range 400-470 MHz appears on the face of the FCC Grant of Certification for a Part 90 Certification. This frequency range is regarded as usual & customary by United States Federal Government and its various departments, user organizations and the military to appear on the face of the equipment Grant of Certification. (1) Shenzhen HYT Science & Technology Co., Ltd.’s Marketing Department plans to ensure that USA users, other than those specifically identified in this letter, not operate within bands 400-406.1 MHz, as controlled by the users’ FCC station license. (2) This device will not be marketed to USA users, other than those identified in the letter, namely the US Government and its various departments & military, for operation in 400-406.1 MHz frequency range.
