Immunity information (to other than radiation/conduction)
The following is a declaration related to the electromagnetic immunity of
the equipment.
Guidance and declaration by manufacturer – Electromagnetic emission – CISPR14
The equipment is intended to be used in the electromagnetic environment designated below.
Client or user of the equipment is requested to confirm the equipment will be operated in such
environment.

If user of the equipment requires a
continuous operation even during
failure of main source, use of
uninterruptible power supply or
battery is recommended as power
source for the equipment.
Magnetic field

The magnetic field intensity of
source frequency must be
comparable to the level
characteristics of the magnetic field
in standard commercial or hospital
environment.
Note: As U
T
, AC main source voltage has the precedence of applied test level.
