Please slide the power switch to “OFF” position after using ; FCC Warning: 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. 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.

1) How does this device operate? Plug into audio player & similar device and powered from DC 4.5V. 2) Provide information on the device and its antenna. The transmitter’s antenna is same cable as Power line from PCB Trace; this is permanently attached antenna and meets the requirements of the section. 3) How is it installed? The EUT will direct plug into audio connector. And power by DC 4.5V. 4) What test procedure was used? Operating condition is according to ANSI C63.4-2009 5) If tested in a car, how was it configured/tested? N/A 6) Was the tuning range properly verified? The test lab should indicate in the report that the tuning controls were manually adjusted to verify maximum tuning range. EUT was adjusted to work at the selected channels: 88.1 MHz, 88.3 MHz and 88.7 MHz. The EUT will not allow operation below 88.1 MHz and will not allow operation above 107.9 MHz. 7) Was the bandwidth properly tested with maximum audio input? Emissions from the intentional radiator shall be confined within a band 200 kHz wide centered on the operation frequency. The 200 kHz band shall lie wholly within the frequency range of 88.1 – 87.9MHz. Setup the EUT and simulators as shown in the report. Enable RF signal and confirm EUT active. Modulate output capacity of EUT up to specifications. 8) Provide the test report. Test Report Submitted.
