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 o and on, the user is encouraged to try to correct the interference by one 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 dierent from that to which the receiver is connected. Safety Precautions - Consult the dealer or an experienced radio/TV technician for help. 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. Radiation Exposure Statement: The product comply with the FCC portable RF exposure limit set forth for an uncontrolled environment and are safe for intended operation as described in this manual. The further RF exposure reduction can be achieved if the product can be kept as far as possible from the user body or set the device to lower output power if such function is available. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. 7 2 Contents & Information CONTENTS & INFORMATION . . . . . . . . . . . . . . . . . . . . . 23 OVERVIEW . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .45 SAFETY PRECAUTIONS . . . . . . . . . . . . . . . . . . . . . . . . . . . 67 OPERATION . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 Setting Up Keyboard and Mouse . . . . . . . . . . . . . . . . . 8-11 WARRANTY . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 SPECIFICATIONS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 TROUBLESHOOTING . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 SCAN HERE FOR MORE PRODUCT INFORMATION AND LEAVE US A REVIEW!

Applicable Standards FCC Part 2(Section 2.1093) FCC KDB 447498 D04 Interim General RF Exposure Guidance v01 2. Exposure Evaluation of Portable or Mobile Devices Human exposure to RF emissions from portable devices (47 CFR §2.1093), as defined by the FCC, must be evaluated with respect to the FCC-adopted limits for SAR. Evaluation of mobile devices, as defined by the FCC, may also be performed with respect to SAR limits, but in such cases it is usually simpler and more cost-effective to evaluate compliance with respect to field strength or power density limits. For certain devices that are designed to be used in both mobile and portable configurations similar to those described in 47 CFR §2.1091(d)(4), such as certain desktop phones and wireless modem modules, compliance for mobile configurations is also satisfied when the same device is evaluated for SAR compliance in portable configurations. The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 300 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. Page 3 of 3 Report No. ESTE-R2510096 3. Evaluation Results For 2.4G SRD Field strength = 74.14dBuV/m@3m P={ [10 (74.14/20) /10 6 *3] 2 /30 }*1000mW =0.007732 mW< 2.72mW 1. Limited= 3060*(0.5/20)^(- (where f is in GHz); 2. We choose 2.480GHz to calculate limit as lower frequency will have higher limits. End of Test Report
