Group 1
The care-e-vac 3 uses RF energy only for its internal function. Therefore, it's RF emissions are very low and are not likely to cause any
interference in nearby electronic equipment.

where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter

Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey*, should be less than
the compliance level in each frequency range**.
Interference may occur in the vicinity of equipment marked with the following symbol:
Note 1 U t is the a.c. mains voltage prior to application of the test level.
Note 2 At 80 MHz and 800 MHz, the higher frequency range applies.
* Field strengths from fixed transmitters, such as base station 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 asses 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 care-e-vac 3 is used exceeds the applicable RF compliance level above, the care-e-vac 3 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the care-e-vac 3.
** 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 Communications Equipment and the care-e-vac 3
The care-e-vac 3 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The user of the care-e-vac 3 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the care-e-vac 3 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 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.
