a.Field strengths of fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM broadcast and television
transmission cannot be theoretically predicted with accuracy. To evaluate the electromag-
netic environment based on fixed RF transmitters, an electromagnetic assessment should
be considered. If the measured field strength at the location where the ri-scope L/EliteVue is
used exceeds the above-mentioned RF degree of compliance, the ri-scope L/EliteVue should
be observed to ensure normal operation. If abnormal performance is observed, additional
measures may be required, such as reorienting or moving the ri-scope L/EliteVue.
Recommended distances between portable and mobile RF communications equipment and
the ri-scope® L/EliteVue.
Recommended distances between portable and mobile RF communications equipment and
the ri-scope® L/EliteVue.
The ri-scope L/EliteVue is intended for use in an electromagnetic environment in which RF
emissions are controlled. The customer or user of the ri-scope L/EliteVue can help to avoid
electromagnetic interference by observing the minimum distance between portable and mo-
bile RF communications equipment (transmitters) and the ri-scope L/EliteVue in accordance
with the maximum output power of the communication equipment.

For transmitters rated at a maximum output power not listed above, the recommended
distance in metres (m) can be estimated using the equation applicable to the frequency of
the transmitter, where P is the maximum output power rating 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.
Note 2: These guidelines may not apply in all situations. The electromagnetic
propagation is affected by absorption and reflection by structures,objects and people.
