For transmitters rated at a power not listed above, the DISTANCE can be estimated using the
equation in the corresponding column, where P is the power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
NOTE: These are guidelines. Actual conditions may vary.
2.4.4 Limitations Management
Adhering to the distance separation recommended in Table 3-12, between 150 KHz & 2.5 GHz,
will 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 (800 MHz to 2.5 GHz carrier frequency) shall be put 23 meters
(see (*) Table 3-12) apart from the Innova system (in order to avoid images interferences risks).
2.4.5 Use Limitation
The use of accessories, transducers, and cables other than those specified may result in degraded
