the following symbol:
NOTE 1 At 80 MHz and 800 MHz, 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.
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 THD2FE is used exceeds the applicable RF compliance
level above, the THD2FE should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the THD2FE.

CISPR 11
Group 1
The THD2FE uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely
to cause any interference in nearby electronic equipment.

RECOMMENDED SEPARATION DISTANCES
BETWEEN PORTABLE AND MOBILE RF
COMMUNICATIONS EQUIPMENT AND THE THD2FE
The THD2FE is intended for use in an electromagnetic
environment (for home healthcare) in which radiated RF
disturbances are controlled. The customer or the user of the
THD2FE can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the THD2FE
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.
