Guidance and Manufacturer’s Declaration – Electromagnetic
Immunity
The Corometrics Antepartum Monitor, Model 171, is intended for use
in the electromagnetic environment specified below. It is the
responsibility of the customer or user to assure that the Corometrics
Antepartum Monitor, Model 171, is used in such an environment.

Fieldstrengths from fixedRFtransmitters, as determined byan
electromagnetic site surveya, should be less than the
compliance level in each frequency rangeb.
Interferencemayoccur in thevicinityofequipment 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 reflection from structures, objects,
and people.
aField strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile 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 equipment is used exceeds the applicable RF compliance level above,
the equipment should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the equipment.
bOver the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
