should be considered. If the measured field strength in the location in which the PTS ii Personalized Tourniquet
System is used exceeds the applicable RF compliance level above, the PTS ii Personalized Tourniquet System should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the PTS ii Personalized Tourniquet System.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
EMC GUIDANCE AND DECLARATION – IMMUNITY/SEPARATION DISTANCES
Recommended separation distances between portable and mobile RF communications equipment and the
PTS ii Personalized Tourniquet System
The PTS ii Personalized Tourniquet System is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the PTS ii can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and
the PTS ii as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
meters (m) can be estimated 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.
