  AudioStar Pro. Install and operate the GSI AudioStar Pro according to the EMC information presented on this page and the next 4 pages. The GSI AudioStar Pro has been tested for EMC emissions and immunity as a standalone instrument. Do not use the GSI AudioStar Pro adjacent to or stacked with other electronic equipment.

• Page 116: Guidance And Manufacturer’s Declaration — Electromagnetic Emissions

  Guidance and Manufacturer’s Declaration — Electromagnetic Emissions The GSI AudioStar Pro is intended for use in the electromagnetic environment specified below. The customer or the user of the GSI AudioStar Pro should assure that it is used in such an environment.

  Guidance and Manufacturer’s Declaration — Electromagnetic Immunity The GSI AudioStar Pro is intended for use in the electromagnetic environment specified below. The customer or the user of the AudioStar Pro should assure that it is used in such an environment.

• Page 118: Guidance And Manufacturer’s Declaration — Electromagnetic Immunity

  To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the AudioStar Pro is used exceeds the applicable RF compliance level above, the AudioStar Pro should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the AudioStar Pro.
