ACQ-7700 / Type 3 Installation Manual Declaration Electromagnetic Emissions/Immunity
•
21
Guidance and manufacturer’s declaration - electromagnetic immunity
The equipment is intended for use in the electromagnetic environment specified below. The customer or the user of the
equipment should assure that it is used in such an environment.
Immunity test IEC 60601 test level Compliance
level Electromagnetic environment - guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the
equipment, including cables, than the recommended
separation distance calculated from 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 and
d is the distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in each
frequency range.
Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE 1: At 80MHz and 800MHz, 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.
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 equipment is used exceeds the applicable RF
compliance level above, the equipment should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the equipment.
Over the frequency range 150kHz to 80MHz, field strengths should be less than 10V/m.
