9.3 GUIDANCE AND MANUFACTURER’S DECLARATION —
ELECTROMAGNETIC IMMUNITY
The Hausted APC Series Models and Surgi-Chairs are intended for use in the electromagnetic environment
specified below. The customer or the user of the Hausted APC Series Models and Surgi-Chairs should assure
that it is used in such an environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the Hausted
APC Series Models and Surgi-Chairs, including cables,
than the recommended separation distance calculated
from the equation applicable to the frequency of the
transmitter.
Recommended separation distance
d = 1.2√P
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 800 MHz to 2,5 gHz
where P is the maximum output power rating of the
transmitter in watts (w) according to the transmitter
manufacturer and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey, should
be less than the compliance level in each frequency
range.
b
Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which the Hausted APC Series
Models and Surgi-Chairs are used exceeds the applicable RF compliance level above, the Hausted APC Series
Models and Surgi-Chairs should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocation the Hausted APC Series Models and
Surgi-Chairs.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
