Operator’s Manual ZM-520PA/521PA/530PA/531PA 9
WARNING
Do not use the same transmitter for
more than one patient at the same
time. Do not connect different sensors
from different patients to the same
transmitter.
WARNING
This transmitter is not waterproof. If
detergent or liquid spills into the
transmitter, stop using it and contact
your Nihon Kohden representative. If a
wet transmitter is used, the patient or
operator may receive an electrical
shock or injury.
WARNING
Close the battery case cover during
operation. If the transmitter is used with
the battery case cover open, anyone
who touches the opened battery case
may receive an electrical shock when
defibrillation is performed. Touching the
opened battery case may cause
electrostatic discharge and
intermittently interfere with the
waveform or data.
WARNING
Do not diagnose a patient based only
on data acquired by the transmitter.
Overall judgement must be performed
by a physician who understands the
features, limitations and characteristics
of the transmitter and by reading the
biomedical signals acquired by other
instruments.
WARNING
When the signal is unstable, keep the
patient under close observation. When
the signal is unstable, the monitoring
and alarm are not reliable and the
receiving monitor cannot detect a
sudden change of the patient’s
condition. This may cause critical
changes in the patient condition to be
overlooked. Install an appropriate
antenna system to ensure stable signal
condition.
WARNING
While the “ALARMS SUSPENDED”
message is displayed on the
transmitter, all alarms on the receiving
monitor are suspended so keep the
patient under close observation.
WARNING
When the patient returns to the bed,
turn on the transmitter and check that
the monitoring is resumed on the
receiving monitor.
WARNING
If the transmitter is not turned off and
monitoring continues for the selected
interval, pause monitoring is canceled
and monitoring continues. Check that
the monitoring is resumed on the
receiving monitor.
