USER MANUAL AND MAINTENANCE
Guide and manufacturer’s declaration – electromagnetic immunity
Tribike is designed to function in the electromagnetic environment indicated below. The customer or
user of Tribike must guarantee that it is used in such an environment
Immunity

Electromagnetic environment
Portable and mobile RF communications equipment
should not be used closer to any part of Tribike,
including
cables, than the recommended
separation distance calculated with the equation
applicable
to the transmitter frequency.
Recommended distance:
Radiated RF
IEC 61000-4-3
3 V/m
from 80 MHz
to 2,5 GHz
20 V/m
d= 0,17 √P from 80 MHz to 800 MHz
d =0,35 √P from 800 MHz to 2.5 GHz
Where P is the maximum rated output power of
the transmitter, in watts (W), according to the
manufacturer of the transmitter and D is the
recommended distance, in meters (m).
Field strengths of fixed RF transmitters determined by
an electromagnetic site
a survey should be lower than
the compliance level for each frequency range
b
.
Interferences can occur in proximity of
appliances marked with the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the separation distance for higher frequency ranges applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is influenced by the
absorption and reflection of structures, objects and people.
a
Field strengths for fixed transmitters, such as base stations for radio telephones (cordless phones) and land
mobile radios, amateur radio equipment, AM FM radio transmitters and TV transmitters can not be predicted
theoretically with precision. To assess an electromagnetic environment caused by fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the place where TRIBIKE
is used exceeds the applicable compliance level above, the operation of TRIBIKE should be monitored. If
abnormal performance is noted, additional measurement may be required as a different orientation or
position of the
Tribike.
b
The field strength in the frequency range 150 kHz to 80 MHz should be less than 3 V / m
