Guidelines
The recommended electromagnetic environment for this instrument is shown in the table
below. The customer or user should ensure that it is used in the described environment.
No part of the NYA Quanta Wireless Home health management System should be placed
near portable and mobile radio-frequency communications equipment. The recommended
safety distance can be calculated using the radio frequency and the following formula.
Radio-frequency
IEC 61000-4-6
Radio-frequency

80 MHz to 800MHz
d =2.33

800MHz to 2.5 GHz
P is the maximum output of the
transmitter (Unit: Watt)
d is the recommended safety
distance (Unit: Meter)
The field intensity of the fixed RF
transmitter (after an EM site
survey) should be lower than the
recommended values for the above
frequency ranges.
Interference may be produced near
instruments that have the
following symbol:
The field intensity of fixed RF transmitters (e.g. radio, mobile phone, ham radio, FM and AM
radio broadcasts and TV stations) cannot be predicted from the frequency alone. To evaluate
the EM field intensity of the environment, an EM site survey may be necessary. If the
measured field intensity for a region exceeds the above recommended range, the device
should be observed or checked to make sure it operates normally. If abnormal operation is
observed, further action such as adjusting the direction or re-positioning of the equipment
should be taken.
Attention: For frequencies between 80 MHz and 800 MHz, use the higher frequency range.
Attention: These guidelines may not be applicable to all situations. Electromagnetic waves
can be absorbed or reflected by buildings, objects and people.
