H3YADYTECH699T900MHZ Wireless Speaker System ( Transmitter)

Intertek Testing Services ETL SEMKO November 2,1999 Dear sir / madam, On October 27,1999, we sent the electronic file to apply the FCC certification. The FCCID is H3YADYTECH699T. But we found that there has some typing errors on the report page 13 and 14, now we sent two correct pages to you and saved with filename: report1.doc. Thank you for your kindly attention and help. Best Regards, Prudence S. M. Poon

Harmonic emissions not detected at the 3-meter distance were measured at 0.3-meter and an inverse proportional extrapolation was performed to compare the signal level to the 3-meter limit. No other harmonic emissions than those reported were detected at a test distance of 0.3-meter. 3. Negative value in the margin column shows emission below limit. 4. Horn antenna and average detector are used for the emission over 1000MHz. *Emission within the restricted band meets the requirement of part 15.205.
