Electromagnetic Immunity
Note:
The monitor is intended for use in the electromagnetic environment specified below. The customer, or
user, of the monitor should ensure that it is used in such an environment
.

is the AC mains voltage prior to application of the test level. All power line immunity tests
were performed at 120 VAC/60 Hz and 230 VAC/50 Hz.
