Electromagnetic environment – guidance
Conducted RF
(IEC 61000-4-6)
3 Vrms
150 KHz to 80 MHz
6 Vrms
ISM bands
a
Portable and mobile RF communications equipment should
be used no closer to any part of the RNS
®
System,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
b, c
d
= 1.17√P
(80 MHz to 800MHz)
d
= 2.33√P
(800 MHz to 2.7 GHz)
Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survey
d
, should be less than the
compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked
with the following symbol:
Radiated RF
(IEC 61000-4-3)
3, 10, 20 V/m
80 MHz to 2.7 GHz
e
a
Conducted immunity of the Tablet (model 5000), Remote Monitor (model 5100), and Wand (model
W-02) compliant to 6 V/m in the ISM bands.
b
Separation distance relevant to Programmer (model PGM-300) and Remote Monitor (model DTR-
300). At 80 MHz and 800 MHz, the higher frequency range applies.
c
These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
d
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 cannot 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 RNS
®
System is used exceeds the applicable RF compliance level above, the
RNS
®
System should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the RNS
®
System.
e
Radiated immunity of the Programmer (model PGM-300), Remote Monitor (model DTR-300-E)
compliant to 3 V/m up to 2.5 GHz. Tablet (model 5000), Remote Monitor (model 5100) and Wand
(model W-02) compliant to 10 V/m to 2.7 GHz and spot frequencies with pulse modulation and to 20
V/m in the communication passband. Spot frequencies tested are: 385 MHz, 450 MHz, 710 MHz,
745 MHz, 780 MHz, 810 MHz, 870 MHz, 930 MHz, 1.720 GHz, 1.845 GHz, 1.970 GHz, 2.450 GHz,
5.240 GHz, 5.500 GHz, 5.785 GHz.
