The X Series unit might not perform to specifications when stored at the upper or lower
extreme limits of storage temperature and then immediately put into use. The X Series unit
should not be stored or used outside of the environmental limits provided in Appendix A of this
manual.

Avoid using the X Series adjacent to, or stacked on, other equipment. If unavoidable, verify that
the unit operates normally in this configuration before clinical use.

The X Series unit should be installed and put into service according to the EMC information in
Appendix A of this manual.

Do not use internal paddles while the X Series unit’s auxiliary power source is connected to an
aircraft AC power operating at a frequency of 400 Hz.

The use of accessories, transducers, and cables other than those specified in this manual and
related X Series option manual inserts may result in increased emissions or decreased immunity
of the X Series.

Perform functional test of internal paddles prior to use.

Do not use or place the unit in service if the Ready For Use indicator (at the upper right of the
front panel) displays a red circle with a line through it.

Carefully route patient cables to avoid tripping over them, or inadvertently pulling the unit onto
the patient.

Always inspect the unit for damage if it has been dropped.

Only authorized personnel should use the Supervisor menus.

If uncertain about the accuracy of any measurement, first check the patient’s vital signs by
alternate means, and then make sure the monitor is functioning correctly.

ECG Monitoring

Implanted pacemakers might cause the heart rate meter to count the pacemaker rate during
incidents of cardiac arrest or other arrhythmias. Dedicated pacemaker detection circuitry may
not detect all implanted pacemaker spikes. Check the patient's pulse; do not rely solely on heart
rate meters. Patient history and physical examination are important factors in determining the
presence of an implanted pacemaker. Pacemaker patients should be carefully observed. See
“Pacemaker Pulse Rejection:” on page A-15 of this manual for disclosure of the pacemaker
pulse rejection capability of this instrument.

Use only ECG electrodes that meet the AAMI standard for electrode performance
(AAMI EC-12). Use of electrodes not meeting this AAMI standard could cause the ECG trace
recovery after defibrillation to be significantly delayed.

Prior to attempting synchronized cardioversion, ensure the ECG signal quality is good and that
sync markers are displayed above each QRS complex.

Do not place electrodes directly over an implanted pacemaker.

The X Series unit detects ECG electrical signals only. It does not detect a pulse (effective
circulatory perfusion). Always verify pulse and heart rate by physical assessment of the patient.
Never assume that the display of a nonzero heart rate means that the patient has a pulse.

Excessive artifact can result due to improper skin preparation of the electrode sites. Follow skin
preparation instructions in Chapter 6: “Monitoring ECG.”
