Welch Allyn CP 200 Electrocardiograph
General Cautions
The following caution statements apply to electrocardiograph use in general. Caution
statements that apply specifically to particular procedures, such as connecting the patient
cable or performing an ECG test, appear in the corresponding sections of the manual.
Caution statements indicate conditions or practices that could damage the equipment or
other property.
Caution When removing the electrocardiograph from storage, allow it to
thermally stabilize to surrounding environmental conditions before using it.
Caution To prevent possible damage to the keypad, do not use sharp or hard
objects to press keys. Only use fingertips.
Caution Do not expose the patient cable to strong ultra-violet radiation.
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 or
stepped on. If the cable’s impedance is altered, 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 supplied with the device and available
through Welch Allyn. The use of accessories other than those specified may
result in degraded performance 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-
1-2:2000 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 as described under
“EMC Guidance and Manufacturer’s Declarations”
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, or servicing.
