Warning Failure to properly set up, use, and care for this product can increase the risk of serious injury or death, or damage to the device or devices. Read this guide and keep all printed guides for future reference. For replacement guides, go to www.microsoft.com/hardware or refer to the Customer Support Options section for contact information. This document includes important information about many Microsoft products. Refer to sections that apply to the features of your device: Important Safety Information AC-Powered Devices Battery-Powered Devices Headset Devices Webcam Devices Wireless Devices Keyboard and Mouse Devices Devices with Laser Pointers All Devices Laser and LED Specifications Regulatory Information Radio Frequency Technical Specifications Radio and TV Interference Regulations Disposal of Waste Batteries and Electrical and Electronic Equipment Statement of Compliance with EU Directives Patent Information Customer Support Options This symbol identifies safety and health messages in this Product Guide and other product manuals . Important Safety Information AC-Powered Devices These precautions apply to all products that plug into a standard wall power outlet. Failure to take the following precautions can result in serious injury or death from electric shock or fire or in damage to the device. M X121690305mnl.indb 25/21/2008 3:15:52 PM 3 To select an appropriate power source for your device: ● Use only the power supply unit and AC power cord that came with your device or that you received from an authorized repair center. ● Confirm that your electrical outlet provides the type of power indicated on the power supply unit (in terms of voltage [V] and frequency [Hz]). If you are not sure of the type of power supplied to your home, consult a qualified electrician. ● Do not use non-standard power sources, such as generators or inverters, even if the voltage and frequency appear acceptable. Only use AC power provided by a standard wall outlet. ● Do not overload your wall outlet, extension cord, power strip, or other electrical receptacle. Confirm that they are rated to handle the total current (in amps [A]) drawn by the device (indicated on the power supply unit) and any other devices that are on the same circuit. To avoid damaging the power cords and power supply: ● Protect the power cords from being walked on. ● Protect cords from being pinched or sharply bent, particularly where they connect to the power outlet, the power supply unit, and the device. ● Do not jerk, knot, sharply bend, or otherwise abuse the power cords. ● Do not expose the power cords to sources of heat. ● Keep children and pets away from the power cords. Do not allow them to bite or chew on them. ● When disconnecting the power cords, pull on the plug — do not pull on the cord. If a power cord or power supply becomes damaged in any way, stop using it immediately. Unplug your device during lightning storms or when unused for long periods of time. For devices with an AC power cord that connects to the power supply, always connect the power cord according to the following instructions: 1 Plug the AC power cord into the power supply until it stops. 2 Plug the other end of the AC power cord into the wall outlet. Battery-Powered Devices These precautions apply to all products that use rechargeable or disposable batteries. Improper use of batteries may result in battery fluid leakage, overheating, or explosion. Released battery fluid is corrosive and may be toxic. It can cause skin and eye burns, and is harmful if swallowed. To reduce the risk of injury: ● Keep batteries out of reach of children. ● Do not heat, open, puncture, mutilate, or dispose of batteries in fire. ● Do not mix new and old batteries or batteries of different types (for example, carbon-zinc and alkaline batteries). ● Do not allow metal objects to touch the battery terminals on the device; they can become hot and cause burns. X121690305mnl.indb 35/21/2008 3:15:52 PM  ● Remove the batteries if they are worn out or before storing your device for an extended period of time. ● Always remove old, weak, or worn-out batteries promptly and recycle or dispose of them in accordance with Local and National Disposal Regulations. ● If a battery leaks, remove all batteries, taking care to keep the leaked fluid from touching your skin or clothes. If fluid from the battery comes into contact with skin or clothes, flush skin with water immediately. Before inserting new batteries, thoroughly clean the battery compartment with a damp paper towel, or follow the battery manufacturer’s recommendations for cleanup. Disposable (non-rechargeable) batteries only: ● Caution Risk of explosion if battery is replaced by an incorrect type. Use and replace only with the correct size and type (alkaline, zinc-carbon, or zinc-chloride) of batteries. Rechargeable batteries only: ● Caution Risk of explosion if battery is replaced by an incorrect type. Use and replace only with the same type and rating as the batteries provided. ● Charge only with the recharger provided with the product. Lithium button cell batteries only: ● Perchlorate Material — special handling may apply. See: www.dtsc.ca.gov/hazardouswaste/perchlorate Headset Devices Extended exposure to high volumes when using a headset may result in temporary or permanent hearing loss. To prevent damage…

PREPARED BY : , DATE:Dec. 31, 2014 ( Annie Chang / Supervisor ) APPROVED BY : , DATE:Dec. 31, 2014 ( Rex Lai / Assistant Manager ) Report No.: SA141217D04 5 of 6 Report Format Version 5.0.1 2. EVALUATION RESULT Following FCC KDB 447498 D01 “General SAR test exclusion guidance” The corresponding SAR Exclusion Threshold condition, listed below: 1) The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR,16 where  f(GHz) is the RF channel transmit frequency in GHz .  Power and distance are rounded to the nearest mW and mm before calculation.  The result is rounded to one decim al place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 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. 2) At 100 MHz to 6 GHz and for test separation distances > 50 mm, the SAR test exclusion threshold is determined according to the following: a) [Threshold at 50 mm in step 1) + (test separation distance - 50mm)·( f(MHz)/150)] mW, at 100MHz to 1500 MHz b) [Threshold at 50 mm in step 1) + (test separation distance - 50 mm)·10] mW at > 1500 MHz and ≤ 6 GHz 3) At frequencies below 100 MHz, the following may be considered for SAR test exclusion. a) The threshold at the corresponding test separation distance at 100 MHz in step 2) is multiplied by [1 + log(100/f(MHz))] for test separation distances > 50 mm and < 200 mm. b) The threshold determined by the equation in a) for 50 mm and 100 MHz is multiplied by ½ for test separation distances ≤ 50 mm. c) SAR measurement procedures are not established below 100 MHz. When SAR test exclusion cannot be applied, a KDB inquiry is required to determine SAR evaluation requirements for any test results to be acceptable. Report No.: SA141217D04 6 of 6 Report Format Version 5.0.1 3. SAR TEST EXCLUSION THRESHOLDS Maximum measured transmitter power: Frequency (GHz) Max. Power (mW) Min. test separation distance (mm) SAR test exclusion calculation value (NOTE 2) 1-g SAR test exclusion thresholds Result 2.402 ~ 2.480 1.2 5 0.372 3 Pass NOTE: 1. The antenna type is Printed antenna on PCB with 2.92dBi gain. 2. Calculate SAR test exclusion thresholds from condition “1” formulas. 4. CONCLUSION Since Source-base time average power is below SAR test exclusion power thresholds, the SAR evaluation is not required.
