Do not use the machine in extremely cold, hot, dusty, humid, high-frequency or strong magnetic environment. 13. Do not let the machine fall down or rub against hard objects, otherwise it may cause surface abrasion, battery damage or other hardware damage. 14. Avoid operating the machine in a particularly dry environment to avoid static electricity. 15. Some mobile phones, PCS and pads cannot achieve all functions due to the influence of operating system or other functions. 16. This earphone is not waterproof or moisture-proof. If the product is placed in water or humid air, it may cause damage to the product. FCC Caution. 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. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Note: 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. The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.

FCC ID :N7KP1 RF EXPOSURE EVALUATION METHOD SAR Test Exclusion Thresholds for 100 MHz 6 GHz and 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. 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. Maximum measured transmitter power.

The measuring distance of at 3 m shall be used for measurements at frequency 0.009MHz up to 1GHz,and above 1GHz. b. The EUT was placed on the top of a rotating table 0.8 meters (above 1GHz is 1.5 m) above the ground at a 3 meter anechoic chamber test site. The table was rotated 360 degrees to determine the position of the highest radiation. c. The height of the equipment shall be 0.8 m(above 1GHz is 1.5 m); the height of the test antenna shall vary between 1 m to 4 m. horizontal and vertical polarizations of the antenna are set to make the measurement. d. The initial step in collecting conducted emission data is a spectrum analyzer peak detector mode pre-scanning the measurement frequency range. Significant peaks are then marked and then QuasiPeak detector mode re-measured. e. If the Peak Mode measured value compliance with and lower than Quasi Peak Mode Limit, the EUT shall be deemed to meet QP Limits and then no additional QP Mode measurement performed. f. For the actual test configuration, please refer to the related Item EUT Test Photos. Note:
Both horizontal and vertical antenna polarities were tested and performed pretest to three orthogonal axis. The worst case emissions were reported 3.2.3 DEVIATION FROM TEST STANDARD No deviation Page 20 of 67 Report No.: STS1907032W01 3.2.4 TESTSETUP ARadiated Emission Test-Up Frequency Below 30MHz BRadiated Emission Test-Up Frequency 30MHz~1GHz CRadiated Emission Test-Up Frequency Above 1GHz Page 21 of 67 Report No.: STS1907032W01 3.2.5 EUT OPERATING CONDITIONS The EUT tested system was configured as the statements of 2.4 Unless otherwise a special operating condition is specified in the follows during the testing. 3.2.6 FIELD STRENGTH CALCULATION The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting the Amplifier Gain and Duty Cycle Correction Factor (if any) from the measured reading. The basic equation with a sample calculation is as follows:
FS = RA + AF + CL - AG Where FS = Field Strength CL = Cable Attenuation Factor (Cable Loss) RA = Reading Amplitude AG = Amplifier Gain AF = Antenna Factor For example Frequency FS RA

Use a video trigger with the trigger level set to enable triggering only on full pulses. d. Sweep Time is more than once pulse time. e. Set the center frequency on any frequency would be measure and set the frequency span to zero span. f. Measure the maximum time duration of one single pulse. g. Set the EUT for DH5, DH3 and DH1 packet transmitting. h. Measure the maximum time duration of one single pulse. i. DH5 Packet permit maximum 1600/ 79 / 6 = 3.37 hops per second in each channel (5 time slots RX, 1 time slot TX). Sothe dwell time is the time duration of the pulse times 3.37 x 31.6
