Changes or modification to this system not expressly approved by GE
Medical Systems could cause EMC issues with this or other
equipment. This system is designed and tested to comply with
applicable regulation regarding EMC and needs to be installed and
put into service according to the EMC information stated as follows.
WARNING
Use of portable phones or other radio frequency (RF) emitting
equipment near the system may cause unexpected or adverse
operation.
WARNING
The equipment or system should not be used adjacent to, or
stacked with, other equipment. If adjacent or stacked use is
necessary, the equipment or system should be tested to verify
normal operation in the configuration in which it is being
used.

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.
