Note 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. The electromagnetic propaga-
tion is affected by absorption and reflection by structures, objects and people.
a) Field strengths of fixed transmitters, e.g. base stations for radio (cellular/wireless)
telephones and land mobile radios, amateur radio, AM and FM broadcast and television
transmissions, cannot be theoretically predicted with accuracy. To evaluate the electro-
magnetic environment based on fixed RF transmitters, an electromagnetic assessment
should be considered. If the measured field strength at the location where the diagnostic
instruments uni® I, II, III / econom® is used exceeds the abovementioned RF compli-
ance level, the diagnostic instruments uni® I, II, III / econom® with accessories should
be observed to verify normal operation. If abnormal performance is observed, additional
measures may be required, such as reorienting or moving the diagnostic instruments
uni® I, II, III / econom®.
b) Over the frequency range from 150 kHz to 80 MHz, field strengths should be less
than 3 V/m.
Recommended distances between portable and mobile RF communications equip-
ment and the ri-scope® L.
The diagnostic instruments uni® I, II, III / econom® with accessories are intended for
use in an electromagnetic environment in which RF interference radiation is controlled.
The customer or user of the diagnostic instruments uni® I, II, III / econom® can help
to avoid electromagnetic interference by observing the minimum distance between
portable and mobile RF communications equipment (transmitters) and the diagnostic
instruments uni® I, II, III / econom® in accordance with the maximum output power of
the communication equipment.

For transmitters with a maximum output power not listed above, the recommended dis-
tance 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.
