Mains power quality should be that of a typical

commercial or hospital environment. If the user of

BM 60 requires continued operation during power

mains interruptions, it is recommended that BM 60

is be powered from an uninterruptible power supply

or a battery.

3 A/m 3 A/m

Power frequency magnetic ﬁelds should be at levels

characteristic of a typical location in a typical com

mercial or hospital environment.

NOTE: U

is the a.c. mains voltage prior to application of the test level.
