GUIDANCE AND MANUFACTURER’S DECLARATION – ELECTROMAGNETIC IMMUNITY
The MODEL ST263 is intended for use in the electromagnetic environment specified below. The customer or the user of the MODEL
ST263 should assure that it is used in such an environment.

Mains power quality should be that
of a typical commercial or hospital
environment. If a dips or an interruption
of mains power occurs, the current of the
MODEL ST261 may be dropped off from
normal level, it may be necessary to use
uninterruptible power supply or a battery.

IEC 61000-4-8 3 A/m 3A/m Power frequency magnetic fields
should be at levels characteristic of a
typical location in a typical commercial
or hospital environment.
