mobile radios, amateur radio, AM and FM broadcasting and television broadcasting can not be predicted
theoretically accurately. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic examination should be considered. If the measured field strength at the location where the e-
scope® is used exceeds the above RF compliance level, the e-scope® should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be required, such as reorienting or
shifting the e-scope®.

Recommended distances between portable and mobile RF communications equipment
and the e-scope®
The e-scope® is intended for use in an electromagnetic environment in which RF emissions
are controlled. The customer or user of the e-scope® can help to avoid electromagnetic
interference by observing the minimum distance between portable and mobile RF
communications equipment (transmitters) and the e-scope® in accordance with the maximum
output power of the communication equipment.

For transmitters with a maximum output power not listed above, the recommended distance d
in metres (m) can be estimated using the equation for the transmitter frequency, where P is the
maximum output power of the transmitter in watts (W). according to the transmitter
manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance applies to the higher frequency
range.
