connecting or disconnecting electrodes to/from a patient.
The use of multiple instruments connected to the same patient may pose a safety
hazard due to the summation of leakage currents from each instrument. Any
combination of instruments should be evaluated by local safety personnel before
being put into service.
Do not pull on the paper while a report is being printed. This can cause distortion of
the waveform and can lead to potential misdiagnosis.
WARNI NG (#A05 or StressWriter Options only) Equipment connected to the cardiograph’s RS-
232 connector can cause ground leakage currents exceeding the maximum specified
in IEC601-1 safety standards.
Do not connect any equipment to the RS-232 connector during cardiograph
operation unless you can verify that the leakage current is within the specified
limits.
CAUTION Do not block the ventilation slots. Lack of ventilation may cause the
cardiograph to overheat, resulting in failure of internal electronic components.
NOTE The Agilent Technologies warranty is only assured if you use Agilent
Technologies approved accessories and replacement parts. See Maintaining
the Cardiograph for more information.
Electromagnetic Compatibility
When using the PageWriter 200/300pi, electromagnetic compatibility with
surrounding devices should be assessed.
A medical device can either generate or receive electromagnetic interference.
Testing for electromagnetic compatibility (EMC) of the PageWriter 200/300pi
cardiograph has been performed according to IEC 601-1-2. This IEC standard
has been adopted in Europe as the European Norm (EN 60601-1-2).
This EMC standard describes tests for both emitted and received interference.
Emission tests deal with interference generated by the device being tested.
