VER.100 User’s Manual | ET 23KM VER.100 FCC Information to User 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 en ergy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that inte rference 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 eq uipment off 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 different from that to which the receiver is con-nected. • Consult the dealer or an experienced radio/TV technician for help. Caution Modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. FCC Compliance Information : This device complies with Part 15 of the FCC Rules. Op eration 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 IMPORTANT NOTE: FCC RF Radiation Exposure Statement: This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centim eters between the radiator and your body.This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

MAGICSING Karaoke (Wireless Microphone) Model name: EX23DT FCC ID: PBN-EX23DT 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. (2) This device must accept any interference received, Including interference that may cause undersired operation. RATED: DC 3.0V (AA* 2ea) Made in Korea

The operator can not program transmit frequencies using the equipment's external operation. The RF chip (CC2400) in this tranceiver operates with a frequency range of 2400-2483MHz and 1MHz channel steps are possible, but the product at the factory is set to be operating at 2403-2477 MHz and 5.2MHz channel steps (16 channel). And user can not change arbitrarily set has been designed.

FCC ID: PBN-EX23DT ATTACHMENT ** MPE Calculations ** The MPE calculation for this exposure is shown below. The peak radiated output power (EIRP) is calculated as follows: EIRP = P + G EIRP = 9.07 dBm + 3.423 dBi EIRP = 12.49 dBm Where, P = Power input to the antenna (mW) G = Power gain of the antenna (dBi) Power density at the specific separation: S = PG/(4R 2 π) S = (8.07 *2.20) / (4 * 20 2 * π) S = 0.0035 mW/cm 2 Where, S = Maximum power density (mW/cm 2 ) P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) The Maximum permissible exposure (MPE) for the general population is 1 mW/cm 2 . The power density does not exceed the 1 mW/cm 2 limit. Therefore, the exposure condition is compliant with FCC rules. Estimated safe separation: R = √(PG / 4π) R = √(8.07*2.20 / 4π) R = 1.19 Cm Where, P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) The numeric gain(G) of the antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain / 10) G = Log -1 (3.423 / 10) G = 2.20
