Table 12. Guidance and Manufacturer’s Declaration —Electromagnetic Immunity
The BladderScan BVI 3000 system is intended for use in the electromagnetic environment specied below. The
customer or the user of the BladderScan BVI 3000 system should assure that it is used in such an environment.

transmitter manufacturer and d
is the recommended separation

an electromagnetic site survey,

should be less than the compliance
level in each frequency range.
b
Interference may occur in the
vicinity of equipment marked with
the following symbol:
Note: Ut is the AC mains voltage prior to application of the test level.
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
reection from structures, objects and people.
a. Field strengths from xed 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 xed RF transmitters, an electromagnetic site survey should be considered. If the measured eld strength in the location in which the
BladderScan BVI 3000 system is used exceeds the applicable RF compliance level above, the BladderScan BVI 3000 system should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re‑orienting or
relocating the BladderScan BVI 3000 system.
b. Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
