• The device needs special precautions regarding electromagnetic compatibility (EMC) and needs to be installed and put into
service according to the EMC information provided in the ACCOMPANYING DOCUMENTS;
• Portable and mobile RF communications equipment can affect the device.
• Warning that the use of accessories, transducers and cables other than those specified with the exception of transducers
and cables sold by the manufacturer of the device as replacement parts for internal components, may result in increased
EMISSIONS or decreased IMMUNITY of the device.
• Warning that the device should not be used adjacent to or stacked with other equipment.
During Voltage Dips test, the product will change its operation state from on to off, after test, it needs operator to press on/off
button to recover. This phenomenon does not affect BASIC SAFETY or ESSENTIAL PERFORMANCE, according the standard,
it's deemed to comply with the requirement.

Electromagnetic environment – guidance
The DEVICE 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.
It is possible to use the device in all establishments,
including domestic establishments and those directly
connected to the public low-voltage power supply network
that supplies buildings user for domestic purposes.
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

Recommended separation distances between portable and mobile RF communications
equipment and the DEVICE
The DEVICE is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of the DEVICE can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the DEVICE 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 determined
using the equation 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 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.
a.
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 DEVICE is
used exceeds the applicable RF compliance level above, the DEVICE should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the DEVICE.
b.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Electromagnetic environment – guidance
Portable and mobile RF communications
equipment shouldbe used no closer to any
part of the device, including cables, than the
recommended separation distance calculated
from that equation applicable to the frequency of
the transmitter.
Recommended separation distance:
80 MHz to 800 MHz
800 MHz to 2,5 GHz
where P is the maximum output power rating
of the transmitter in watts (W) according to
the transmitter manufacturer and d is the
recommended separation distance in metres (m).
