The Philips HeartStart FRx is one of the most advanced defibrillators available on the commercial market. It has superior ease yet rugged enough for everyday use making the device a favorite of first responders.
However, what about when you’re not using the FRx and it’s stored safely in the aed wall cabinet or the back or a police car. Even when the device is not being use the FRx is contnousluly running self diagnostics to verify that it will be ready when needed.
The HeartStart FRx will automatically perform daily tests on its critical components including the battery, pads, and internal circuits. After running its daily self-diagnostic, if the device finds any issues it will alert you by “chirping” and the I-button will flash until someone responds.
When you respond to the “chirping” from the device, your first step is to press the I-button. Once pressed, the FRx will provide audio instructions as to what needs to be addressed. If you’re battery model # has been depleted, it will let you know.
You can also manually test the defibrillator at any time by simply removing the battery for 5 seconds and then reinstalling it. The entire self-test process will take less than one minute to complete. It is recommended that you only run an entire self test in this method once in a while because it will drain the battery faster.
It is recommended that you run the battery insertion self-test only:
- When you first purchase your defibrillator
- After each use the defibrillator should be tested
- After replacing the battery
- Anytime you think the defibrillator may have been damaged
Special Note: If the FRx turns off when you install the battery instead of running the battery insertion self-test, check to be sure that the pads case is not open. If the pads case is open, the FRx assumes that it may be in use and so will not run the self-test.
There are two batteries available for the Philips FRx. There is an FRx Aviation Battery model # 98903139301 that is perfect those who will store or operate the device in airplanes. There is also the standard lithium manganese dioxide that is available for those who will not use the device in an plane.
