Operation is subject to the following two conditions:

(1) This device may not cause harmful interference,

(2) This device must accept any interference received, including interference that may cause undesired operation. 15.21 The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. In cases where the manual is provided only in a form other than paper, such as on a computer disk or over the Internet, the information required by this section may be included in the manual in that alternative form, provided the user can reasonably be expected to have the capability to access information in that form 15.105 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. FCC Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. Tech Support: 386-257-1187 460 Walker Street, Holly Hill, FL 32117 www.MetraOnline.com

OUTPUT POWER TEST 8.1.Limit (FCC Part 15C 15.247 b(3)) For systems using digital modulation in the 24002483.5MHz, The Peak output Power shall not exceed 1W(30dBm), As an alternative to a peak power measurement, compliance with the one Watt limit can be based on a measurement of the maximum conducted output power. Maximum Conducted Output Power is defined as the total transmit power delivered to all antennas and antenna elements averaged across all symbols in the signaling alphabet when the transmitter is operating at its maximum power control level. 8.2.Test Procedure 1, Connected the EUTs antenna port to Spectrum Analyzer. 2, Use the test method descried in ANSI C63.10:

1) Set span to at least 1.5 times the OBW. 2) Set RBW = 1% to 5% of the OBW, not to exceed 1 MHz. 3) Set VBW [3 RBW]. 4) Sweep time = auto. 5) Detector = peak 6) Trace mode = max hold 7) Allow trace to fully stabilize; Use peak marker function to determine the peak amplitude level. Note: The cable loss needs to be compensated into the data. 8.3.Test Results Pass Channel Frequency

POWER SPECTRAL DENSITY TEST 9.1.Limit 9.2.Test Procedure For digitally modulated systems, the power spectral density conducted from the intentional radiator to the antenna shall not be greater than 8dBm in any 3kHz band during any time interval of continuous transmission. Use the test method descried in ANSI C63.10 clause 11.10.2:

a) b) c) d) e) f) g) h) i) Set analyzer center frequency to DTS channel center frequency. Set the span to 1.5 times the DTS bandwidth. Set the RBW to 3 kHz RBW 100 kHz. Set the VBW [3 RBW]. Detector = peak. Sweep time = auto couple. Trace mode = max hold. Allow trace to fully stabilize. Use the peak marker function to determine the maximum amplitude level within the RBW. If measured value exceeds requirement, then reduce RBW (but no less than 3 kHz) and repeat. j) 9.3.Test Results Pass Channel Frequency(MHz) CH00 CH19 CH39 2402 2440 2480 ConclusionPASS Power density

Standard Applicable For intentional device, according to FCC 47 CFR Section 15.203, an intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. And according to FCC 47 CFR Section 15.247 (b), if transmitting antennas of directional gain greater than 6dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi. 10.2. Antenna Connected Construction The antennas used for this product are PCB antenna that no antenna other than that furnished by the responsible party shall be used with the device, the maximum peak gain of the transmit antenna is -3dBi.
