Getting Acquainted
LED Safety
The infrared port located on the side panel of the cardiograph is classified as a Class
I LED device according to IEC 825-1 (EN 60825-1). Although this device is not
considered harmful, avoid direct eye exposure to the infrared LED beam and do not
attempt to view the infrared LED beam with any type of optical device.
Using the Cardiograph During Defibrillation
Be aware of the following conditions when using the M2662A cardiograph during
defibrillation.
• Use Agilent recommended disposable electrodes (M2253A/M2254A, 13946B and
13943D). Use of any other electrodes may prevent the ECG signals from reap-
pearing on the display 10 seconds after defibrillation.
• Set the Baseline Wander filter setting of the cardiograph to 0.5Hz. Using any other
Baseline Wander filter setting may prevent the ECG signals from reappearing on
the display 10 seconds after defibrillation. Refer to Chapter 4 of this book, "Con-
figuring the Cardiograph" for information on setting filters.
• Double pressing 10 seconds after defibrillation can reduce ECG recovery
time.
1AC and Battery Operation
For information about installing or replacing the battery, refer to Appendix A,
“Setting Up Your Cardiograph”. The M2662A cardiograph can operate with battery
only, with AC only or with both battery and AC.
If your cardiograph operates with AC only (without battery), disconnecting the
cardiograph from AC can cause the loss of configuration information. In this case,
you need to configure your cardiograph again.
