Guidance and manufacturer's declaration
Electromagnetic IMMUNITY for ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
The TOPRO TAURUS is intended for use in the electromagnetic environment specified below.
The customer or the user of the TOPRO TAURUS should assure that it is used in such an environment.

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 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 mea-
sured field strength in the location in which the TOPRO TAURUS is used exceeds the applicable RF compliance level above, the
TOPRO TAURUS should be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as re-orienting or relocating the TOPRO TAURUS.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and
the ME EQUIPMENT or ME SYSTEM for ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
The TOPRO TAURUS is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the TOPRO TAURUS can help prevent electromagnetic interference by maintaining a minimum dis-
tance between portable and mobile RF communications equipment (transmitters) and the TOPRO TAURUS as recommended
below, according to the maximum output power of the communications equipment.

Portable and mobile RF communications equipment should
be used no closer to any part of the TOPRO TAURUS, inclu-
ding cables, than the recommended separation distance
calculated from the equation applicable to the frequency of
the transmitter.

d=1,16√P
d=1,16√P 80 MHz – 800 MHz
d=2,33√P 800 MHz – 2,5 GHz

where P is the maximum output power rating of the trans-
mitter in watts (W) according to the transmitter manufactu-
rer and d is the recommended separation distance in metres
(m). Field strengths from fixed RF transmitters, as determi-
ned 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 equip-
ment marked with the following symbol:

Main power quality should be that of a ty-
pical commercial or hospital environment.
If the user of the TOPRO TAURUS requires
continued operation during power mains
interruptions, it is recommended that the
TOPRO TAURUS be powered from an uninte-
rruptible power supply or a battery.
Power frequency magnetic fields should be
at levels characteristic of a typical location
in a typical commercial or hospital environ-
ment.
