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
Syringe Pump is used exceeds the applicable RF compliance level above, the Syringe Pump should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Syringe Pump.
d Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10V/m.

portable and mobile RF communications equipment and the Syringe Pump
The Syringe Pump is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Syringe Pump can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and
the Syringe Pump 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 metres (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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to 6.79
MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
NOTE 3 An additional factor of 10/3 is used in calculating the recommended separation distance for transmitters i
the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz to
decrease the likelihood that mobile/portable communications equipment could cause interference if it is
