The Product should not be used adjacent to or stacked with
other equipment. If adjacent or stacked use is necessary,
the Product should be observed to verify normal operation in
the configuration in which it will be used.
CAUTION:
Systems Statement
Equipment connected to the product must be certified to the
respective IEC Standards (i.e. IEC 950 for data processing
equipment and IEC 601-1 for medical equipment).
Furthermore, all configurations shall comply with the system
standard IEC 601-1-1. Anybody who connects additional
equipment to the signal input part or signal output part
configures a medical system, and is therefore, responsible
that the system complies with the requirements of the system
standard IEC 601-1-1. The product service port is only
intended for use during maintenance by authorized service
personnel.
CAUTION:

When disinfecting the case, use a non-oxidizing disinfectant,
such as ammonium salts or glutaraldehyde based cleaning
solution, to avoid damage to the metal connectors.
CAUTION:
Environment of use
The product is designed for indoor use. Operator must
confirm that the environment of use meets the required
operating environmental specifications before using.
CAUTION:
Cold Environments
If the product is stored in an environment with a temperature
below the operating temperature, the unit should be allowed
to warm up to the needed operating temperature before
using.
