Electromagnetic environment – guidance
Floors should be wood, concrete or ceramic tile. If floors are covered
with synthetic material, the relative humidity should be at least 30 %.
Mains power quality should be that of a typical commercial or
hospital environment.
Mains power quality should be that of a typical commercial or
hospital environment.
Mains power quality should be that of a typical commercial or hospital
environment. If the user of the TH1001 requires continued operation
during power mains interruptions, it is recommended that the TH1001
be powered from an uninterruptible power supply or a battery.
Power frequency magnetic fields should be at levels characteristic of
a typical location in a typical commercial or hospital environment.

Recommended separation distances between
portable and mobile RF communications equipment
and the ME EQUIPMENT or ME SYSTEM
The TH1001 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the TH1001 can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the TH1001 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.
