Recommended separation distance between portable and mobile RF communications equipment and REF 5513E/5514 series
REF 5513E/5514 series is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled� The customer or the user of
REF 5513E/5514 series can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and REF 5513E/5514 series 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�
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�
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 REF 5513E/5514 series is used exceeds the applicable
RF compliance level above, REF 5513E/5514 series should be observed to verify normal operation� If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating REF 5513E/5514 series�
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m�
