Front Satellite Speakers Before attaching the cables, position the two front satellite speakers on either side of your computer monitor or television about the same distance from each other as from you. Angle them to face you. Place the two rear speakers behind you and about the same distance apart as the front speakers. Your Logitech® Z-5450 speaker satellites are wall mountable. Unscrew the satellite stand from the satellite speaker base, exposing the stability pins on the base. Rotate the speaker stand 180 degrees and reattach the stand to the base, ensuring the stability pins line up with the openings provided. Do not over tighten the screw. Mount the speakers using appropriate wall anchors through the holes in the stands. For a pro-audio look, remove the cloth grilles by pulling them straight off. Removing the grilles will not affect sound quality. 2.

Per 15.203, the antenna is internal and permanently attached. It is not intended to be serviced by the customer and is, therefore only serviceable by Logitech, Inc. authorized personnel. The antenna is a quarter wave dipole with 2dBi peak gain.

Compliance with 47 CFR 15.247(i) “Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission's guidelines. See § 1.1307(b)(1) of this chapter.” The EUT is a surround sound speaker system that operates in the 2400-2483.5MHz band as a 15.247 frequency hopping transmitter.. The EUT will only be used with a separation distance of 20 centimeters or greater between the antenna and the body of the user or nearby persons and can therefore be considered a mobile transmitter per 47 CFR 2.1091(b). The antenna is a quarter wave dipole antenna that is permanently attached to the unit. The antenna has a gain of 2.0 dBi. The maximum peak conducted output power is 53.58 mW. The maximum peak power is 84.918 mW (EIRP) for FCC ID: DZLA-0181ACP. The transmit frequency is 2403 – 2478 MHz. Since the transmit frequency is greater than 1.5 GHz, and the output power is less than 3 W ERP, the EUT is categorically excluded from routine environmental evaluation per 47 CFR 2.1091(c). The MPE estimates are as follows: Table 1 in 47 CFR 1.1310 defines the maximum permissible exposure (MPE) for the general population as 1 mW/cm 2 . The exposure level at a 20 cm distance from the EUT’s transmitting antenna is calculated using the general equation: S = (PG)/4πR 2 Where: S = power density (mW/cm 2 ) P = power input to the antenna (mW) G = numeric power gain relative to an isotropic radiator R = distance to the center of the radiation of the antenna (20 cm = limit for MPE estimates) PG = EIRP Solving for S, the maximum power density 20 cm from the transmitting antenna is summarized in the following table: The power density does not exceed 0.0.17 mW/cm 2 at 20 cm; therefore, the exposure condition is compliant with FCC rules. The applicant’s radio, FCC ID: DZLA-0181ACP, is compliant with the requirements of 15.247(i).
