Immunity to proximity fields from RF wireless communication equipment

7.2
The portable or mobile RF communication devices that may be present in the home, such as wireless
telephones, mobile phones, devices for wireless connection to the Internet and similar, must be kept
at a distance from BIOSTIM SPT, to avoid the risk of interference. The recommended minimum
separation distance depends on the output power of the RF device and the transmission frequency.
The user can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications systems and BIOSTIM SPT, using reference the table
below.

The immunity levels shown in the table are respected as long as the device is maintained at a
distance of at least 30 cm from any possible source of RF disturbance.
BIOSTIM SPT, complies with all test levels with a distance >= 30 cm.
Note: BIOSTIM SPT, at the frequency of 450 Mhz is immune to the disturbance up to a level of 20V /
m - To obtain the required immunity level (28 V / m) the distance from the source of disturbance must
be increased to not less than 42cm.

SYMBOLS

Class II appliance: Appliance in which protection against electric shock does not
rely on basic insulation only, but includes additional safety precautions such as
double insulation.
Appliance with BF type applied part: appliance with a specific degree of protection
against electrical hazards, specifically regards admissible leakage current, and with
an F type (floating) applied part isolated from the rest of the appliance (coil).
Continuous current: on the generator data plate indicates the required power
supply, on the power supply data plate indicates the provided power supply.
Alternate Current (AC): on the power supply data plate indicates the required power
supply.
