Sunrise company tried to emphasizes on the importance of maintaining a recommended separation distance between the system and portable or mobile RF communications equipment, based on the transmitter frequency. It states that field strengths from fixed RF transmitters should be below the compliance level in each frequency range. Equipment marked with a specific symbol may cause interference in its vicinity. The system’s normal operation should be observed, and appropriate measures should be taken if any abnormal performance is noticed. Guidelines for separation distances between portable and mobile RF communications equipment and the BrightSpeed System are provided. The use of accessories, transducers, and cables not specified may lead to degraded electromagnetic compatibility. Proper grounding and shielding of interconnect cables are necessary to minimize the risks of interference. The BrightSpeed System is intended for use in non-domestic environments and should be connected to a dedicated power supply system. It is advised to avoid stacking or placing the system adjacent to other equipment. The document also specifies requirements for low-frequency magnetic field, static magnetic field limits, and electrostatic discharge environment.

Before initiating the installation of the BrightSpeed systems, it is essential to ensure that all pre-installation requirements have been fulfilled. Site-specific items need to be verified, and construction sites should be avoided due to the potential for dust, dirt, and chemical contamination. The walls, ceiling, and flooring must be completed before installation can commence. Phone lines for optional modem use should also be installed. The gantry and table must be properly leveled and positioned according to the provided templates.

Furthermore, a list of system options requiring site planning work is provided. The base scanner system includes hardware and software for whole-body computed tomography. It is recommended to discuss room size dimensions and required system clearances with a GE Sales and Service Representative.
