Guidance and Manufacturer’s Declaration for Electromagnetic Immunity
The CR-2 is intended for use in the electromagnetic environment specified below.
The customer or the user of the CR-2 should assure that it is used in such an environment.

If the user of the CR-2 requires continued
operation during power mains interruptions,
it is recommended that the CR-2 be powered
from an uninterruptible power supply.

Power frequency magnetic fields should be
at levels characteristic of a typical location in
a typical commercial or hospital environment.
NOTE: U
