ELECTROMAGNETIC IMMUNITY
APPENDIX
The Hausted A.P.C. Series Models and Surgi-Chairs are intended for use in the electromagnetic environ-
ment specified below. The customer or the user of the Hausted A.P.C. Series Models and Surgi-Chairs
should assure that it is used in such an environment.

Mains power quality should be that
of a typical commercial or hospi-
tal environment. If the user of the
Hausted A.P.C. Series Models and
Surgi-Chairs require continued
operation during power mains inter-
ruptions, it is recommended that
the Hausted A.P.C. Series Models
and Surgi-Chairs be powered from
an uninterrupted power supply or a
battery.

should be at levels characteristic of
a typical location in a typical com-
mercial or hospital environment.
