NSK Surgic Pro Series - EMC Information; Electromagnetic Emissions Guidance

Portable and mobile RF communications equipment should be
used no closer to any part of the Surgic Pro series, including
cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
Recommended separation distance
= 1.2
= 1.2 80MHz to 800MHz
= 2.3 800MHz to 2.5GHz
Where is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer, and ( ) is
the recommended separation distance in meters (m).
Fie
ld strengths from fixed RF transmitters as determined by an
electromagnetic site survey(a) should be less than the compliance
level in each frequency range(b).
Interference may occur in the vicinity of equipment marked with
the following symbol:

Surgic Pro series is intended for use in the electromagnetic environment specified below.
The customer or the user of the Surgic Pro series should assure that it is used in such an environment.
NOTE1 At 80MHz and 800MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. 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 cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which the Surgic Pro series is used exceeds the applicable RF
compliance level state
d above, the Surgic Pro series should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating the Surgic Pro series.
b Over the 150kHz to 80MHz frequency range, the field strength should be less than 3V/m.
The Surgic Pro series is intended for use in an electromagnetic environment in which radiated RF disturbances are control LCD. The customer or the user of the
Surgic Pro series can help prevent electromagne
tic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Surgic Pro series 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.
