NOTE 1: With regard to 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not be applicable in every case. Buildings, objects
and persons influence the propagation of electromagnetic waves by absorption
and reflection.
An exact technical estimate of the field intensity of stationary transmitters such
as base stations of mobile phones and land mobile radio devices, amateur radio
stations, AM and FM radio broadcast and television stations is not possible.
In order to determine the electromagnetic environment with regard to stationary
transmitters one should consider a survey of the location. If the field intensity
measured at the location where the
THERA-Trainer will be used exceeds the
conformity levels listed above, one should observe the THERA-Trainer in order to
check if it is working correctly and as intended. Should any performance irregularities
occur, it might be necessary to take additional measures such as modifications
or a change of locations
THERA-Trainer.
In the frequency range between 150 kHz and 80 MHz, the field intensity should be
below 3 V/m.
Directives and manufacturer's declaration – Immunity to electromagnetic disturbance
The THERA-Trainer is designed for operation in an electromagnetic environment as described below.
The customer or the user of the THERA-Trainer should make sure that the unit is used in such an environment.

Portable and mobile radio equipment
should not be used closer to the
THERA-Trainer (including line) as
the protective distance recommended.
The equation for the transmission
frequency in question is used to
calculate it.
Recommended protective distance:
d = [3.5/3] *
P = 1.17 * P
d = [3.5/3] * P = 1.17 * P
for 80 MHz to 800 MHz
d = [7.0/3] *
P = 2.33 * P
for 800 MHz to 2.5 GHz
with P as the transmitter's power rating
in watts (W) according to the indications
of the transmitter manufacturer and d as
the recommended protective distance in
metres (m).
An on-site test should show that the field
intensity of stationary radio transmitters
are below the compliance level with all
frequencies.
Disturbances are possible in the vicinity
of equipment labelled as follows.
