The Defibtech Lifeline verbally tells you what is wrong with the unit if it encounters a problem following a self-test. Both electrode pads and the battery have the expiry date printed.
A common error is the electrode pads being unnecessarily unplugged from the unit. When these are plugged back in, the battery does not recognise that they are present and thus causes the device to beep. A battery low in power will also cause the device to bleep.
Please see below a quick guide to checking the defibrillator:
250 - No - Means battery was inserted prior to the pads - you should take them both out and insert the pads first.
Please ensure that you do the manual self-test. Martek require hearing the customer do this test to ensure they can claim on the defibrillator's limited warranty. Before Martek would collect the unit, they will have the customer perform the self-test. The customer is required to cooperate and perform this as they may incur a cost of around £150.
