• Field strengths from fixed RF transmitters must be less than the compliance level in each frequency range. At
frequencies between 150 kHz to 80 MHz, field strengths must be less than [V2] V/m.
Note:
Field strengths from fixed transmitters, such as base stations for cellular telephones and land mobile radios,
amateur radio, AM and FM radio broadcast, and TV broadcast cannot be estimated accurately. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey must be performed.
If the measured field strength exceeds the RF compliance level above, monitor the Senographe to check nor-
mal operation in each use location. If abnormal performance is observed, additional measures may be neces-
sary, such as re-orienting or relocating the Senographe.
• Interference can occur in the vicinity of equipment marked with the following symbol:
• No portable or mobile RF communications equipment can be used closer to any part of the Senographe,
including cables, than the recommended separation distance calculated from the equation appropriate to the
frequency of the transmitter. See Table 4.
Note:
These are guidelines. Actual conditions can vary.

At this disturbance level, the monitor image can present some
slight flicker. If this occurs, the monitor can be removed from
the vicinity of the electrical field source to improve image qual-
ity.
At this disturbance level, the system is fully operational.
