23.1 Electromagnetic immunity
Guidance and manufacturer's declaration - electromagnetic immunity
The SLE1000 is intended for use in the electromagnetic environment specified below. The customer or the user of the
SLE1000 should assure that it is used in such an environment.
Immunity test IEC 60601 test level Compliance level Electromagnetic

the SLE1000 requires
continued operation during
power mains interruptions,
it is recommended that the
SLE1000 be powered from
an uninterruptible power
aupply or a battery.
