2AJGM-M4Two Way Radio

M4 Series Two-way Radios OWNER’S MANUAL English Preface To help you ward off bodily injury or property loss that may arise from improper operation, please read all the information carefully before using our products. Intended Use Our products are designed to provide reliable wireless communication services for users across many industry sectors. In order to use the products safely and to achieve the best performance, they must be used as intended. The operator of the product is responsible for damage to the product or damage caused by the product if the product was used beyond the intended use instructions. Intended use includes that: ● The product is used by users who have full knowledge of its RF exposure and can exercise control over their RF exposure to meet the occupational limits in FCC/ICNIRP and international standards. ● All the security instructions set forth in this document are always heeded. ● The general, national and in-house safety regulations are heeded. ● The product is exclusively used with the frequencies licensed by the respective authority. ● The product is configured appropriately by the dealer. Besides, intended use also requires the product operator to be well-trained and to be familiar with the applicable standards, regulations and provisions. RF Radiation Information Compliance with RF Exposure Standards The radio complies with the following RF energy exposure standards and guidelines: ● United States Federal Communications Commission, Code of Federal Regulations; 47 CFR § 1.1307, 1.1310 and 2.1093 ● American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers (IEEE) C95. 1:2005; Canada RSS102 Issue 5 March 2015 ● Institute of Electrical and Electronic Engineers (IEEE) C95.1:2005 Edition RF Exposure Compliance and Control Guidelines and Operating Instructions To control your exposure and ensure compliance with the occupational/controlled environmental exposure limits, always adhere to the following procedures. Guidelines: ● Do not remove the RF Exposure Label from the device. ● User awareness instructions should accompany device when transferred to other users. ● Do not use this device if the operational requirements described herein are not met. Operating Instructions: ● Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), press the Push-to-Talk (PTT) key. To receive calls, release the PTT key. Transmitting 50% of the time, or less, is important because the radio generates measurable RF energy only when transmitting (in terms of measuring for standards compliance). ● Keep the radio unit at least 2.5 cm away from the face. Keeping the radio at the proper distance is important as RF exposure decreases with distance from the antenna. The antenna should be kept away from the face and eyes. ● When worn on the body, always place the radio in an approved holder, holster, case, or body harness or by use of the correct clip for this product. Use of non-approved accessories may result in exposure levels which exceed the FCC's occupational/controlled environmental RF exposure limits. ● Use of non-approved antennas, batteries, and accessories causes the radio to exceed the FCC RF exposure guidelines. ● Contact your local dealer for the product's optional accessories. Radiation Exposure Statement Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. For Remote controller, SAR tests are conducted using standard operating positions accepted by the FCC/ISEDC with the device transmitting at its highest certified power level in all tested frequency bands, although the SAR is determined at the highest certified power level, the actual SAR level of the device while operating can be well below the maximum value. Before a new model device is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the exposure limit established by the FCC/ISEDC, Tests for each device are performed in positions and locations (e.g. at the ear and worn on the body) as required by the FCC/ISEDC. For body worn operation, this model device has been tested and meets the FCC/ISEDC RF exposure guidelines when used with an accessory designated for this product or when used with an accessory that Contains no metal and that positions the handset a minimum of 10 mm from the body. Non-compliance with the above restrictions may result in violation of RF exposure guidelines. Safety Information for Radios Your wireless handheld portable transceiver contains a low power transmitter. When the talk button is pushed, it sends out radio frequency (RF) signals. The device is authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal Communications Commissions(FCC) adopted RF exposure guidelines with safety levels for handheld wireless devices. This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference. Important FCC RF Exposure Requirements: For body-worn operation, this radio has been tested and meets the FCC RF exposure guidelines when used with Pofung accessories supplied or designated for this product. Use of other accessories may not ensure compliance with FCC RF exposure guidelines. Use only the supplied antenna. Unauthorized antennas, modifications or attachments could damage the transmitter and may violate FCC regulations. FCC Regulations Federal Communication Commission (FCC) requires that all radio communication products should meet the requirements set forth in the above standards before they can be marketed in the U.S, and the manufacturer shall post a RF label on the product to inform users of operational instructions, so as to enhance their occupational health against exposure to RF energy. FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital devi…
