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. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. INFORMATION: 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 WARNING: This equipment may generate or use radio frequency energy. Changes or modifications to this equipment may cause harmful interference unless the modifications are expressly approved in the instruction manual. Modifications not authorized by the manufacturer may void users authority to operate this devices. 1 2 3 Depending on the quality of the disc, and the condition of the recording, some CD-R/CD-RW discs may not be playable. 1.Always place the compact disc in the disc tray with the label facing upward. (Compact discs can be played only on one side). 2.To move a disc from its storage case, press down on the center of the case and lift the disc out, holding it carefully by the edges. 3.If the disc becomes dirty, wipe the surface from the center hole outward towards the outer edge with a soft, dry cloth. 4.Never use such chemicals as record spray, antistatic sprays or fluid, benzine or thinner to clean the discs. Such chemicals will do irreparable damage to the disc's plastic surface. 5.Discs should be returned to their cases after use to avoid serious scratches that could cause the laser pick up to skip. 6.Do not expose discs to direct sunlight or high humidity and temperature for extended periods. Long exposure to high temperatures will warp the discs. 7.Printable CD-R and CD-RW discs are not recommended, as the label side might be sticky and damage the unit. 8.Use a soft oil-based felt-tipped pen to write the information on the label side. Never use a ball-point or hard-tipped pen, as this may cause damage to the recorded side. 9.Do not use CDs with an irregular shape (octagonal, heart-shaped, business card size, etc). CDs of this sort can damage the unit. 10.If you have any doubts of using CD-R/CD-RW disc, read the precautions supplied with the disc, or contact the disc manufacturer directly.

FCC ID: 2AYB7696137 Portable device According to §15.247(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to KDB447498 D01 General RF Exposure Guidance V06 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] * [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where f(GHz) is the RF channel transmit frequency in GHz； Power and distance are rounded to the nearest mW and mm before calculation； The result is rounded to one decimal place for comparison； The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. We use 5mm as separation distance to calculate. Maximum measured transmitter power: Mode Transmit Frequency (GHz) Max Conducted Power (dBm) tune up maximum power(dBm) Result calculation 1-g SAR 8DPSK 2.402 1.59 2.0 0.5 3 Conclusion: For the max result : 0.5 ≤ 3.0 for 1-g SAR extremity SAR, No SAR is required.
