c. 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 Crius V6 ventilator is used exceeds the applicable RF
compliance level above, the Crius V6 ventilator should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the Crius V6 ventilator.
d. Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distance between portable and mobile
RF communications equipment and the Crius V6 ventilator
The Crius V6 ventilator is intended for use in an electromagnetic environment in which radiated RF
disturbance are controlled. The customer or the user of the Crius V6 ventilator can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Crius V6 ventilator as recommended below,
according to the maximum output power of the communications equipment.
