The device is intended for use in the electromagnetic environments listed below, and should
only be used in such environments:
The device is intended for use in the electromagnetic environments listed below, and should
only be used in such environments:
RF energy is used only to maintain device’s operation.
Therefore, its RF emissions are so low that it’s not likely
to cause any interference in nearby electronic equipment.
The device is suitable for use in all establishments,
including domestic establishments, and those
directly connected to the public low-voltage power
supply network that supplies buildings used for
domestic purposes.
In the case of air discharge testing, the
climatic conditions shall be within the
following ranges:
Ambient Temperature:15°C~35°C,
Relative Humidity:30%~60%.
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
communication equipment and the device.
The device is intended for use in an electromagnetic environment where radiated RF
disturbances are under control. User can help prevent electromagnetic interference by keeping
the device at a minimum distance from portable and mobile RF communications equipment
(transmitters). Below table details the maximum output power of transmitter:
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 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.
