E-Tech Co., Ltd. Installation requirements for compliance with Radio Frequency(RF) energy Exposure Safety Standards.

[ Warning ]

Your FM 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, 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 FM 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. 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. ALWAYS use E-TECH authorized accessories (antennas, batteries, speaker/mics, etc). Use of unauthorized accessories can cause the FCC RF exposure compliance requirements to be exceeded. 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. E-Tech Co., Ltd. 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.

[ Important ]

Be sure that antenna installation is per chapter 5 of users manual. Electromagnetic Interference / Compatibility During transmissions, your 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.

Antenna Installation 5-1 Antenna Installation and Compliance with Radio Frequency(RF) Energy Safety Standards

[IMPORTANT NOTE]

To assure optimum performance and compliance with RF Energy Safety standards, this antenna installation guidelines and Instructions are limited to metal-body vehicles with appropriate ground planes and take into account the potential exposure of backseat passengers and bystanders outside the vehicle.

[NOTE]

For mobile radios with rated power of 7 watts or less, the only installation restrictions are to use only E-tech approved antennas and install the antenna externally on metal body vehicles. For mobile radios with rated power greater than 7 watts, always adhere to all the guidelines and restrictions in 5.2 below. FILE: IM400 Service manual.doc 2004.11.23 E-TECH Co., Ltd 18/19 5-2 Selecting an Antenna Site/Location on a Metal Body Vehicle 1. External installation Check the requirements of the antenna supplier and install the vehicle antenna external to a metal body vehicle in accordance with those requirements. 2. Roof top For optimum performance and compliance with RF Energy Safety standards, mount the antenna in the center area of the roof. 3. Trunk lid On some vehicles with clearly defined, flat trunk lids, the antenna of some radio models (see restrictions below) can also be mounted on the center area of the trunk lid. For vehicles without clearly defined, flat trunk lids (such as hatchback autos, sport utility vehicles, and pick-up trucks), mount the antenna in the center area of the roof. Before installing an antenna on the trunk lid. Be sure that the distance from the antenna location on the trunk lid will be at least 60cm (24 inches) from the front surface of the rear seat-back to assure compliance with RF Energy Safety standards. Ensure that the trunk lid is grounded by connecting grounding straps between the trunk lid and the vehicle chassis. If these conditions can not be satisfied, then mount the antenna on the roof top !

4. Mounting restrictions for certain radio models For more than 40 Watt VHF models, the 1/4 wave antenna should be mounted only in the center area of the roof, not on the trunk lid, to assure compliance with RF Energy Safety standards. 5. Ensure that the antenna cable can be easily routed to the radio. Route the antenna cable as far away as possible from any vehicle electronic control units and associated wiring. 6. Check the antenna location for any electrical interference. 7. Make sure any other mobile radio antenna on this vehicle is at least 30.48 cm (1 foot) away from this antenna.

[NOTE]

Any two metal pieces rubbing against each other (such as seat springs, shift levers, trunk and hood lids, exhaust pipes, etc.) in close proximity to the antenna can cause severe receiver interference. FILE: IM400 Service manual.doc 2004.11.23 E-TECH Co., Ltd 19/19 5-3 Antenna Installation Procedure 1. Mount the antenna according to the instructions provided with the antenna kit. Run the coaxial cable to the radio mounting location. If necessary, cut off the excess cable and install the cable connector. 2. Connect the antenna cable connector to the radio antenna connector on the rear of the radio. 5-4 Completing the Installation 1. Mount the microphone clip to a convenient spot near your radio. 2. Your microphone has a telephone-type connector at the end of is cord. Plug the microphone into the control head connector. 3. To complete your radio installation, plug the power cable into the radio power connector. FILE: IM400 Service manual.doc 2004.11.23
