Table 3: Immunity (not life-supporting devices)
Guidance and manufacturer’s declaration – electromagnetic immunity
UNIUM Devices are intended for use in the electromagnetic environment specified below.
The customer or user of the UNIUM Devices should ensure that they are used in such an environment.
▲ WARNING:
Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in
improper operation. If such use is necessary, this equipment and the other equipment should be observed to verify
that they are operating normally.
Electromagnetic environment – guidance
Portable and mobile RF communications equipment should be used no closer to any part of the UNIUM Devices,
including cables, than the recommended separation distance calculated from the equation applicable to the
frequency of the transmitter.

Interference may occur in the vicinity of equipment marked with the following symbol:
■ Notes:
•
At 80 MHz and 800 MHz, the higher frequency range applies.
•
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
▲ WARNINGS:
•
Do not use device together with HF surgical equipment.
•
Keep distance to mobile HF communication equipment as defined in tables 3 and 4, but at least 30 cm (12 inches).
•
Keep distance to 5G mobile phones.
a Possible shorter distances of outside ISM bands are not considered to have a better applicability of this table.
b 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 electro-
magnetic site survey should be considered. If the measured field strength in the location in which UNIUM Devices are used exceeds the applicable RF compliance
level above, the UNIUM Devices should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the UNIUM Devices.
c Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
