Supplies and Accessories

Use only the multifunction electrode pads, battery, and accessories as listed in this guide. Substitutions
may cause the HeartStart MRx to function improperly.
Use multifunction electrode pads prior to their expiration date. Discard pads after use. Do not reuse
pads. Do not use for more than 8 hours of continuous pacing.

Electromagnetic Compatibility

When using the HeartStart MRx, electromagnetic compatibility with surrounding devices should be
A medical device can either generate or receive electromagnetic interference. Testing for
electromagnetic compatibility EMC with and without the appropriate accessories has been performed
according to the international standard for EMC for medical devices (IEC 60601-1-2). This IEC
standard has been adopted in Europe as the European Norm (EN 60601-1-2).
The EMC standards describe tests for both emitted and received interference. Emission tests deal with
interference generated by the device being tested.
Radio frequency (RF) interference from devices other than the HeartStart MRx may degrade
performance of the HeartStart MRx. Electromagnetic compatibility with surrounding devices should
be assessed prior to using the defibrillator.
Fixed, portable, and mobile radio frequency communications equipment can affect the performance of
medical equipment. See Table 113 for the minimum recommended separation distance between RF
communications equipment and the HeartStart MRx.

Reducing Electromagnetic Interference

The HeartStart MRx and associated accessories may be susceptible to interference from other RF
energy sources and continuous, repetitive, power line bursts. Examples of other sources of RF
interference are medical devices, cellular products, information technology equipment and radio/
television transmission. Should interference be encountered, as demonstrated by artifact on the ECG
or dramatic variations in parameter measurement values, attempt to locate the source. Assess:
• Is the interference intermittent or constant?
• Does the interference occur only in certain locations?
• Does the interference occur only when in close proximity to certain medical devices?
• Do parameter measurement values change dramatically when the AC line cord is unplugged?
Once the source is located, attempt to attenuate the EMC coupling path by distancing the monitor/
defibrillator from the source as much as possible. If assistance is needed, call your local service
