Table 1-10 Separation Distances
Recommended separation distances between portable and mobile RF communications
The BrightSpeed System is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the BrightSpeed System can help
prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the BrightSpeed System as
recommended below, according to the maximum output power of the communications
equipment.
Rated Maximum Output
Power (P) of Transmitter
For transmitters rated at a maximum output power not listed above, the separation distance can
be estimated using the equation in the corresponding column, where P is the maximum output
power rating of the transmitter in watts (W) according to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects, and people.
4.3.1

Limitations Management :

Adhering to the distance separation recommended in
reduce disturbances recorded at the image level but may not eliminate all disturbances. However,
when installed and operated as specified herein, the system will maintain its essential performance
by continuing to acquire, display, and store diagnostic quality images safely.
(*) For example, a 1W mobile phone (800MHz to 2.5GHz carrier frequency) shall be put 2.3 meters
apart from the BrightSpeed System (in order to avoid image interference risks).
4.4

Use Limitation :

4.4.1

External components

The use of accessories, transducers, and cables other than those specified may result in degraded
