NOTE: This equipment generates, uses and can radiate radio frequency energy. The
equipment may cause radio frequency interference to other medical and
non-medical devices and radio communications. To provide reasonable
protection against such interference, this product complies with emissions limits
for a Group 1, Class A Medical Devices Directive as stated in EN 60601–1–2.
However, there is no guarantee that interference will not occur in a particular
installation.
NOTE: If this equipment is found to cause interference (which may be determined by
turning the equipment on and off), the user (or qualified service personnel)
should attempt to correct the problem by one or more of the following
measure(s):
– reorient or relocate the affected device(s)
– increase the separation between the equipment and the affected device
– power the equipment from a source different from that of the affected device
– consult the point of purchase or service representative for further
suggestions
NOTE: The manufacturer is not responsible for any interference caused by using other
than recommended interconnect cables or by unauthorized changes or
modifications to this equipment. Unauthorized changes or modifications could
void the users’ authority to operate the equipment.
NOTE: To comply with the regulations on electromagnetic interference for a Class A
FCC Device, all interconnect cables to peripheral devices must be shielded and
properly grounded. Use of cables not properly shielded and grounded may
result in the equipment causing radio frequency interference in violation of the
FCC regulations.
NOTE: Do not use devices which intentionally transmit RF Signals (cellular phones,
transceivers, or radio controlled products) in the vicinity of the equipment as it
may cause performance outside the published specifications. Keep the power
to these type devices turned off when near this equipment.
The medical staff in charge of this equipment is required to instruct technicians,
patients, and other people who may be around this equipment to fully comply
with the above requirement.
