environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which SE-1515 PC ECG is
used exceeds the applicable RF compliance level above, SE-1515 PC ECG should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating SE-1515 PC ECG.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distances between
portable and mobile RF communications equipment and SE-1515 PC ECG
SE-1515 PC ECG is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of SE-1515 PC ECG can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and SE-1515 PC ECG 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 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
