2-4. Recommended Separation Distances for Portable and Mobile RF Communi-
cations Equipment IEC 60601-1-2
TABLE 4 - RECOMMENDED SEPARATION DISTANCES
Note:
These are guidelines. Actual conditions can vary.
2-5. Use Limitation
• External components:
The use of accessories, transducers, and cables other than those specified can result in the
degraded Electromagnetic compatibility of the Senographe.

• For transmitters rated at a power not listed above, the recommended separation distance (d, in meters) 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.
• (*) For example, a 1 W mobile phone (800 MHz to 2.5 GHz carrier frequency) must be no closer than 23
meters from the Senographe to avoid image interference risks.
• Using the recommended distance as determined from Table 4, between 150KHz and 2.5 GHz, some slight
disturbance can be observed at image level. The disturbance to the image cannot be confused with a medical
pathology, and the equipment retains its medical utility.
