Servicing – The user should not attempt to service the unit beyond those methods described in the user’s operating instructions. Service methods not covered in the operating instructions should be referred to qualified service personnel. English 3 Safety Instructions 18. Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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: o Reorient or relocate the receiving antenna. o Increase the separation between the equipment and receiver. o Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. o 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. This Transmitter must be installed to provide a separation distance of at least 20 cm from all persons. 3 English Controls TOP PANEL REAR REMOTE CONTROL PANEL FRONT PANEL AUX(Gree…

1 INTERTEK TESTING SERVICES RF Exposure report The equipment under test (EUT) is a Bluetooth Speaker. The EUT was powered by AC 100-240V, 50/60Hz, 140W. For more detail information pls. refer to the user manual. Modulation Type: GFSK, ∏/4DQPSK, 8DPSK Bluetooth Version: 2.1 with EDR function and without AFH mode Antenna Type: Integral antenna Antenna Gain: 2.12dBi The nominal radiated output power (e.i.r.p) specified: 0dBm (Tolerance: +/- 3dB) The worst-case radiated emission for the EUT is 95.2dB
V/m at 3m in the frequency 2.441GHz = [(FS*D) ^2 / 30] mW = -0.03 dBm which is within the production variation. The minimum radiated emission for the EUT is 94.7dB
V/m at 3m in the frequency 2.480GHz = [(FS*D) ^2 / 30] mW = -0.53 dBm which is within the production variation. According to FCC Part 2.1091, this unlicensed transmitting devices is categorically excluded from routine environmental evaluation for RF exposure prior to equipment authorization or use, According to the KDB 447498 and OET 65, the simple calculation as below: For Maximum Permissible Exposure (MPE) evaluation of the product, the maximum power density at 20 cm from this transmitter shall be less than the General Population / Uncontrolled MPE limit in OET Bulletin 65. The maximum radiated output power = 3 dBm = 2.0mW The source-based time averaged maximum radiated power (including the tune-up tolerance) = 2.0 * Duty Cycle = 1.7 mW From above data, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: = 1.7 mW / 4πR^2 = 0.0003 mW/cm^2 The MPE limit is 1.0 mWcm-2 for general population and uncontrolled exposure in the Bluetooth frequency range according to FCC Part 1.1310. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be 2 ensured by indicating the minimum 20cm separation between the transmitter's radiating structure and body of the user or nearby persons. Transmitter Duty Cycle Calculation Based on the Bluetooth Specification (BT version: 2.1 with EDR function), transmitter duty cycle is dependent of packet type (DH1, DH3 and DH5). For one period for a pseudo-random hopping through all 79 RF channels, for DH5: One hopset consists of 5 TX slot and 1 RX slot. Duty cycle = 5 / 6 = 0.833 The following RF exposure statement is proposed to be included in the user manual: “FCC RF Radiation Exposure Statement Caution: This Transmitter must be installed to provide a separation distance of at least 20 cm from all persons.”
