CAUTION Do not pull or stretch the patient cable. Doing so could result in
mechanical or electrical failures. Form the patient cable into a loose loop
before storing.
CAUTION Avoid positioning the patient cable where it might get pinched,
stretched, or stepped on. Otherwise, measurements might no longer be
accurate, and repair might be necessary.
CAUTION Using the equipotential terminal for anything but grounding
purposes may contribute to damage of the device.
CAUTION Use only parts and accessories, including thermal paper, that
were supplied with the device and available through Welch Allyn. The use
of accessories other than those specified may result in degraded
performance or unsafe use of this device.
CAUTION Portable and mobile RF communications equipment can affect
the performance of the electrocardiograph.
CAUTION The electrocardiograph meets the Class A requirements of IEC
60601-1-2 regarding incidental emission of radio frequency interference. As
such it is suitable for use in commercial grade electrical environments. If
the electrocardiograph is used in residential grade electrical environments
and you experience incidental interference with other equipment that uses
radio frequency signals to operate, minimize the interference.
CAUTION Other medical equipment—including but not limited to
defibrillators, ultrasound machines, pacemakers, and other stimulators—
may be used simultaneously with the electrocardiograph. However, such
devices may disturb the electrocardiograph signal.
CAUTION The power cord must be disconnected from AC power before
cleaning, maintaining, transporting, or servicing.
CAUTION The requirements of AAMI EC11, Section 3.2.7.2, Frequency
and Impulse Response, for an impulse triangle waveform may be impacted
by up to 5 milliseconds of small amplitude dampened ringing immediately
after the impulse when the muscle filter (35 Hz) is turned on or a small
amplitude offset when the baseline filter (0.5 Hz) is turned on. These filters,
in any combination turned on or off, meet the AAMI requirements.
Measurements performed by the optional interpretation algorithm are
unaffected by any filter selections.
