Limited warrantyWHAT YOUR WARRANTY COVERSThis warranty extends only to the original user of the equipment (“you”, ”your”) and is limited to thepurchase price of each part. Amphony and it’s affiliated companies (”we”, ”our”, ”us”) warrant thisWireless Headphone Set against defects in materials or workmanship as follows. For a period of ninety (90) days from the original date of purchase, if we determine that the equipment is defective subject to the limitations of this warranty, we will replace it at no charge for labor.We warrant any such work done against defects in materials or workmanship for the remaining portion ofthe original warranty period. For a period of one (1) year from the original date of purchase, we will supply, at no charge, new or rebuilt replacement parts in exchange for parts we determine are defective subject to the limitations ofthis warranty. We warrant any such replacement parts against defects in materials or workmanship forthe remaining portion of the original warranty period. ”Parts” means items included in this package. It does include other parts purchased seperately. LABOR:PARTS:Note: not WHAT YOUR WARRANTY DOES NOT COVERLEGAL LIMITATIONSThis warranty consumer instruction, physical setup or adjustment of any consumer electronic equipment, headphone batteries, or signal transmission problems.This warranty cosmetic damage, damage due to the affixing of any attachment not provided with the product, loss of parts, connecting the product to any but the specified receptacles,lightning, electrical surges, fire, flood, or other acts of God, accident, misuse, abuse, repair or alterationby other than authorized service personnel, negligence, commercial or institutional use, or improper orneglected maintenance.This warranty equipment sold AS IS or WITH ALL FAULTS, equipment removal or reinstallation, shipping damage if the equipment was not packed and shipped in the manner weprescribe, nor equipment purchased, serviced, or operated outside the contiguous United States orAmerica.REPLACEMENT AS PROVIDED UNDER THIS WARRANTY IS YOUR EXCLUSIVE REMEDY.

It should be noted thatthe audio level of the audio output should conform to the standard line outputlevel (V ± 1.5 V maximum).If the audio level is too low, the dynamic range of the transmitter is not fullyused. If the audio level is too high, clipping at high audio levels may occur.

Measuring Methods Transmitter Parameter TestS (ß15.209) All transmitter parameter radiated tests are performed at a test distance of 3 meteters in a semianechoic chamberDuring the tests the EUT will be rotated all around and the receiving antenna will be raised and lowered from 1 meter to 4 meter to find the maximum levels of emission. Cables and equipment will be placed and moved within the position likely to find their maximum emissions. Measurements will be made in horizontal and vertical polarization of the receiving antenna. The EUT was operating in transmit mode with its internal modulation. The bandwidth of the emission will be measured with a spectrum analyzer. Resolution Bandwidth and Video Bandwidth will be set to 10 kHz.

A prescan at 3 meter distance will be performed in a shielded room with the detector of the spectrum analyzer or EMI Receiver set to peak. Final measurement is then performed at 30 meter distance. In case the regulation requires testing at other distances, the result will be extrapolated. The extrapolation factor will be determined by making a second measurement at 10 meter distance. The provisions of 15.31 (d) apply. According to section 15.209 (d) final measurementis performed with the detector set to Quasi Peak except for the frequency bands 9 ñ 90 kHz and 110 ñ 490 kHz where average detector is employed. EMV-Pr ̧fzentrum EMI/EMC-Testcenter FCC ID: PMJT1000Test Report No.:50104-10327 Page 9 of 24 Pages Radiated Emissions 30 MHz ñ 1 GHz Radiated emissions in the frequency range 30 ñ 1000 MHz will be measured at a distance of 3 meter. The bandwidth of the spectrum analyzer will be set to 100 kHz and the detector function set to Quasi Peak. The test setup will be made in accordance with ANSI C.63.4-1992. Measurements will be made in horizontal and vertical polarization of the receiving antenna. Prescans will be taken in a semianechoic chamber using a spectrum analyzer with the detector function set to peak. All tests will be performed at a test distance of 3 meters. For final testing an open field test site will be used. During the tests the EUT will be rotated all around and the receiving antenna will be raised and lowered from 1 meter to 4 meterto find maximum levels of emissions. test-distance 3 meters Receiving antenna Spectrum analyzer Wooden Turntable 80 cm high Test fixture with EUT EMV-Pr ̧fzentrum EMI/EMC-Testcenter FCC ID: PMJT1000Test Report No.:50104-10327 Page 10 of 24 Pages Radiated Emissions above 1 GHz Radiated emissions were measured in the frequency range 1 GHz to 3.15 GHz in transmit mode .The resolution bandwidth and the video bandwidth of the spectrum analyzer was set to 1 MHz.
