6.3 Electromagnetic immunity
The BT-550 is intended for use in the electromagnetic environment specified below.
The customer or the user of the BT-550 should assure that it is used in such an
environment.

Mains power quality should
be that of a typical
commercial or hospital
environment. If the user of
the BT-550 image
intensifier requires
continued operation during
power mains interruptions,
it is recommended that the
BT-550 image intensifier be
powered from an
uninterruptible power
supply.

fields should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment.
