User Manual US
Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: These guidelines may not apply in all situation. Electromagnetic
propagation is affected by absorption and reflection from
structures, objects and people.
a. Field strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio,
AM and FM radio broadcast and TV broadcast can not be predicted
theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitter, an electromagnetic site
survey should be considered. If the measured field strength in the
location in which the NIOX VERO
® is used exceeds the applicable RF
compliance level above, the NIOX VERO ® should be observed to
verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or
relocating the NIOX VERO
®
.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should
less than 3.0 V/m.
Recommended separation distances between portable and mobile RF
communications equipment and the NIOX VERO
®
The NIOX VERO ® is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of
the NIOX VERO
®
can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the NIOX VERO
®
as
recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in meters (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: At 80 MHz to 800 MHz, the separation distance for the higher
frequency range applies.
