For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m)
can be determined using the equation applicable to the frequency of the transmitter, where P is the maximum output power
rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for 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.

Electromagnetic environment guidance
Venner PneuX TSM™ uses RF energy only
for its internal functions. Therefore, its RF
emissions are very low and are not likely to
cause any interference in nearby electronic
equipment.
Mains power quality should be that of a
typical commercial or hospital environment.
Mains power quality should be
that of a typical commercial or hospital
environment.
Mains power quality should be that of a
typical commercial or hospital environment.
If the user of Venner PneuX TSM™ requires
continued operation during mains power
interruptions, it is recommended that
Venner PneuX TSM™ be powered from an
uninterruptible power supply or battery.
Power frequency magnetic fields should be
at levels characteristic of a typical location in
a typical commercial or hospital
environment.
Portable and mobile RF communications
equipment should be used no closer to any
part of Venner PneuX TSM™, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
d = 1.2√P
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 800 MHz to 2.5 GHz
Field strengths from fixed RF transmitters,
as determined 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 equipment marked
with the following symbol:
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 measured field strength in the location in which the Venner PneuX TSM™ is used exceeds the
applicable RF compliance level above, the Venner PneuX TSM™ should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
Venner PneuX TSM™.
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.
The Venner PneuX TSM™ is intended for use in the electromagnetic environment in which radiated RF disturbances
are controlled. Users of Venner PneuX TSM™ can help to prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the device as
recommended below, according to the maximum output power of the communication equipment.
