Appendix
Guidance and Manufacturer's Declaration for
Electromagnetic Immunity
The OCT is intended for use in the electromagnetic environment specified below.
The customer or the user of the OCT should assure that it is used in such an
environment.
Due to electromagnetic disturbances, it may be necessary for the customer or the user
of the OCT to take the measurement again or to restart the equipment, the software or
the computer.

Environment – Guidance
Floors should be wood,
concrete or ceramic tile.
If floors are covered
with synthetic material,
the relative humidity
should be at least 30%.
Mains power quality
should be that of a
typical commercial or
hospital environment.

If the user of the OCT
requires continued
operation during power
mains interruptions, it is
recommended that the
OCT 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.
