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 should be performed. If the measured
field strength exceeds the RF compliance level above, observe the Innova system to
verify normal operation in each use location. If abnormal performance is observed,
additional measures may be necessary, such as re–orienting or relocating the Innova
system
**Over the frequency range 150 kHz to 2.5GHz, the recommended field strengths is here
less than 0.3V/m.
The Recommended Separation Distances are listed in
These are guidelines. Actual conditions may vary.

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.
