INFORMATION 
WARNING: 
The use of accessories other than those specified by Fisher & Paykel Healthcare may 
result in increased emissions or decreased immunity
 
of the equipment
 
or system. 
 
Guidance and manufacturer’s declaration – electromagnetic emissions
 
The MR850 is intended for use in the electromagnetic environment specified below. The customer or the user of the MR850 should 
assure that it is used in such an environment.

RF emissions CISPR 11 
Group 1 
The MR850 uses RF energy only for its internal function. 
Therefore, its RF emissions are very low and are not likely to 
cause any interference in nearby electronic equipment.

If the user of the MR850 requires continued 
operation during power mains interruptions, 
it is recommended that the MR850 be 
powered from an uninterruptible power 
supply or a battery.
