Although the Elf Light is generally safe when used responsibly, please exercise the following precautions: Precautions For Laser Usage • Do not aim or shine at people, animals or traffic from land, sea, or air. • Use with caution within 5 nautical miles of an airport. • The Elf Light should always be stationary; do not hold in hand when operating. • Position the Elf Light so that the lights are within the confines of the target object. • Do not use near infants/cribs and keep away from children. IMPORTANT SAFETY INSTRUCTIONS THIS PRODUCT HAS A POLARIZED PLUG (ONE BLADE IS WIDER THAN THE OTHER) AS A FEATURE TO REDUCE THE RISK OF ELECTRIC SHOCK. THIS PLUG WILL FIT IN A POLARIZED OUTLET ONLY ONE WAY. IF THE PLUG DOES NOT FIT FULLY IN THE OUTLET, REVERSE THE PLUG. IF IT STILL DOES NOT FIT, CONTACT A QUALIFIED ELECTRICIAN. NEVER USE WITH AN EXTENSION CORD UNLESS PLUG CAN BE FULLY INSERTED. DO NOT ALTER THE PLUG. 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 distance 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 manufacturer or an experienced radio/TV technician for help. NOTE: This is a standard cautionary statement from the FCC, which is used to alert the user to troubleshoot in various ways if problems are found. Read All Instructions WARNING: When using outdoors, use portable luminaires. Basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury, including the following: a) Use only three-wire outdoor extension cords that have three-prong grounding plugs and grounding receptacles that accept the appliance’s plug. b) Ground Fault Circuit Interrupter (GFCI) protection is to be provided on the circuit(s) or outlet(s) to be used for the wet location portable luminaire. Receptacles are available having built-in GFCI protection and are able to be used for this measure of safety. c) Use only with an extension cord for outdoor use, such as an extension cord of cord type SW, SW-A, SOW, SOW-A, STW, STW-A, STOW, STOW-A, SJW, SJW-A, SJOW, SJOW-A, SJTW, SJTW-A, or SJTOW, SJTOW-A.

RF Exposure evaluation Product Description:REMOTE CONTROL Model Number: 9751 FCC ID: 2ACIG-9751USTX15 According to 447498 D01 General RF Exposure Guidance v05 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, where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation According to the follow transmitter output power（P t ）formula： P t =（E x d） 2 /（30 x g t ） P t =transmitter output power in watts g t =numeric gain of the transmitting antenna (unitess) E=electric field strength in V/m d=measurement distance in meters (m) According to the above test data, Emax=88.7dBuv/m=0.027V/m,d=3m,g t =1 P t =（E x d） 2 /（30 x g t ）=(0.027x3) 2 /(30x1)=0.000218W=0.22mW The result is rounded to one decimal place for comparison Worse case is as below: [433.92MHz -0.22mW output power] (0.22mW /5mm) .[√0.4339(GHz)]= 0.03<3.0 for 1-g SAR Then SAR evaluation is not required NOTE: For the maximum power, you can refer FCC test report.
