Guide and Manufacturer's Declaration - Electromagnetic Immunity
The device is intended for use in the electromagnetic environment specified below. It is advisable that the purchaser or user of the device ensures
that it is used in such an environment.
Electromagnetic environment - guide
Mobile or portable RF communication equipment should not be
used at smaller distances from any part of the device, including
cables, than the recommended separation distance calculated by
the equation applicable to the transmitter frequency.
Recommended separation distance
Irradiated RF
IEC 61000-4-3
d = 0,35 √P 80 MHz a 800 MHz
d = 0,70 √P 800 MHz a 2.5 GHz
Where P is the maximum declared level of transmitter output
power in Watts (W) according to the transmitter manufacturer and
d is the recommended separation distance in meters (m).
The field intensity from fixed RF transmitters, determined by an
electromagnetic survey of field
a
, is less than the compliance level
for each frequency range
Interference may occur in the vicinity of equipment marked with
the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the highest frequency range is applicable.
NOTE 2: These guidelines may not apply to all situations. Electromagnetic propagation is affected by the absorption and reflection of structures, objects and
people.
a - The field intensity of fixed transmitters, such as base stations for radio phones (cellular /wireless), terrestrial mobile radios, amateur radio, broadcasting
broadcasts (AM and FM) and television, cannot, in theory, be accurately predicted. To evaluate the electromagnetic environment caused by fixed RF transmitters,
an electromagnetic inspection of the site should be carried out. If the field strength value at the location where the device is being used exceeds the applicable RF
compliance level mentioned above, the device should be checked for proper operation. If unusual performance is observed, additional measures may be required,
such as changing the position or installation location of the device.
b
- In the frequency range between 150 kHz and 80 MHz, the field intensity should be less than 10 V/m.
