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
Veterinary Monitor is used exceeds the applicable RF compliance level above, the Veterinary Monitor should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Veterinary Monitor .
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
E.4 Recommended separation distance between portable and mobile RF
communications equipment and the EQUIPMENT or SYSTEM for
EQUIPMENT or SYSTEM that are not LIFE-SUPPORTING
Recommended separation distances between portable and mobile RF communications equipment and the
Veterinary Monitor
The Veterinary Monitor is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Veterinary Monitor can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Veterinary Monitor 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.
ATTENTION 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
ATTENTION 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
