DocumentDocumentMOBILE COMPUTER FCC Statement Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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 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 accept any interference received, including interference that may cause undesired operation. SAR Information Statement Your MOBILE COMPUTER is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for exposure to radiofrequency (RF) energy set by the Federal Communications Commission of the U.S. Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. The exposure standard for MOBILE COMPUTER employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. * Tests for SAR are conducted with the MOBILE COMPUTER 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 MOBILE COMPUTER while operating can be well below the maximum value. This is because the MOBILE COMPUTER is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. Before a MOBILE COMPUTER model is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the limit established by the government adopted requirement for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) as required by the FCC for each model. The highest SAR value for this MOBILE COMPUTER when tested for use at the head is 0.58 W/Kg and when worn on the body, as described in this user guide, is 0.77 W/Kg (Body-worn measurements differ among MOBILE COMPUTER models, depending upon available accessories and FCC requirements). The maximum scaled SAR in hotspot mode is 0.78 W/Kg. While there may be differences between the SAR levels of various MOBILE COMPUTER and at various positions, they all meet the government requirement for safe exposure. The FCC has granted an Equipment Authorization for this MOBILE COMPUTER with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this MOBILE COMPUTER is on file with the FCC and can be found under the Display Grant section of http:// www.fcc.gov/ oet/fccid after searching on FCC ID: 2A9LJ-ME74 Additional information on Specific Absorption Rates (SAR) can be found on the Cellular Telecommunications Industry Association (CTIA) web-site at http://www.wow-com.com. * In the United States and Canada, the SAR limit for MOBILE COMPUTER used by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard incorporates a substantial margin of safety to give additional protection for the public and to account for any variations in measurements. The SAR test distance is 10mm. CE Statement Herby, MEFERI TECHNOLOGIES CO., LTD declares that this MOBILE COMPUTERME74 is in compliance with the essential requirements and other relevant provisions of Directive 2014/53/EU. In accordance with Article 10(2) and Article 10(10), this product allowed to be used in all EU member states. Use the MOBILE COMPUTER in the environment with the temperature between -30 and 35, Use careful with the earphone maybe possible excessive sound pressure from earphones and headphones can cause hearing loss. This device will not be marketed or sold on the French market due to non-compliance with the latest SAR requirements. Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions. The product shall only be connected to a USB interface of version USB-C SAR: The device complies with RF specifications when the device used at 5mm from your body. The highest SAR value for this device when tested for use at the head is 0.74W/Kg and when worn on the body is 0.94 W/Kg. Adapter shall be installed near the equipment and shall be easily accessible.
