Compliance with RF Energy Exposure Standards Yo u r HYT two-way radio is designed and tested to comply with a number of national and international standards and guidelines (listed below) regarding human exposure to radio frequency electromagnetic energy. This radio complies with the IEEE (FCC) and ICNIRP exposure limits for occupational/controlled RF exposure environment at duty cycles of up to 50% talk-50% listen and should be used for occupational use only. In terms of measuring RF energy for compliance with the FCC exposure guidelines, your radio radiates measurable RF energy only while it is transmitting (during talking), not when it is receiving (listening) or in standby mode. Note: The approved batteries supplied with this radio are rated for a 5-5-90 duty cycle (5% talk-5% listen-90% standby), even though this radio complies with the FCC occupational RF exposure limits at duty cycles of up to 50% talk. Your HYT two-way radio complies with the following of R F e n e r g y exposure standards and guidelines: z United States Federal Communications Commission, Code of Federal Regulations; 47CFR part 2 sub-part J z American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992 z Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1999 Edition z International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998 Operational Instructions and Training Guidelines To ensure optimal performance and compliance with the occupational/controlled environment RF energy exposure limits in the above standards and guidelines, users should transmit no more than 50% of the time and always adhere to the following procedures: Transmit and Receive To transmit (talk), push the Push-To-Talk (PTT) button; to receive, release the PTT button. Hand-held radio operation Hold the radio in a vertical position with the microphone one to two inches (2.5 to 5 cm) away from the lips. Body-worn operation z Always place the radio in an HYT approved clip, holder, holster, case, or body harness for this product. Use of non-HYT-approved accessories may exceed FCC RF exposure guidelines. Antennas & Batteries z Use only HYT approved, supplied antenna or HYT approved replacement antenna. Unauthorized antennas, modifications, or attachments could damage the radio and may violate FCC regulations. 4 z Use only HYT approved, supplied batteries or HYT approved replacement batteries. Use of non- HYT -approved batteries may exceed FCC RF exposure guidelines. Approved Accessories For a list of HYT approved accessories, see the accessories page of this user manual or visit the following website which lists approved accessories: http://www.HYT.com.cn FCC Compliance This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:  Reorient or relocate the receiving antenna.  Increase the separation between the equipment and receiver.  Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.  Consult the dealer or an experienced radio/TV technician for help. FCC Requirements Your radio must be properly licensed Federal Communications Commission prior to use. Your HYT Wireless dealer can assist you in meeting these requirements. Your dealer will program each radio with your authorized frequencies, signaling codes, etc., and will be there to meet your communications needs as your system expands. Precautions • Only qualified technicians are allowed to maintain this product. • Do not use the radio or charge a battery in explosive areas such as coal gas, dust, steam, etc. • Switch OFF the radio while refueling or parking at gas station. • Do not modify or adjust this radio without permission. • Do not expose the radio to direct sunlight over a long time, nor place it close to heating source. • Do not place the radio in excessively dusty, humid areas, nor on unstable surfaces. Safety: It is important that the operator is aware of and understands hazards common to the operation of any radio. 5 Product Inspection Thank you for your use of HYT portable two-way radio TC3000. Before use, you are recomme…
