kardia not reading my heart rate

[leahfreilich]

had Alive cor installed 2 years ago when I had AF, had ablation 18 months ago and need to take heart rate again, not used Kardia for around 6 months now

No signal - not reading heart rate even though I'm using it properly, wifi on, blue tooth on, on iPhone

I had the same last week. Have you changed the battery ?

[leahfreilich in reply to feejbee]

no, where is the battery? how do I change? and Where do I get one?

[leahfreilich in reply to leahfreilich]

trying to work out how to open the back to get battery out

[momist in reply to leahfreilich]

@Leah. The black plastic should be in a slide fitting glued on the back of your phone, open at one end with little spring clips. Once out of that holder, turn it over and the battery compartment is obvious.

It needs a jewellers screw driver so best take it to a watch shop or somewhere like Timsons.

If it's the same model as mine ,slide it out of the case and turn it over. The opening for the battery is there ( you'll need a sharp object to open it ) . The battery is a 3.0V model CR 2016 coin cell battery . Bought mine from Sainsbury's- £5 for 2.

Hope this helps

Make sure your filter is set on Enhanced

[leahfreilich]

it is set on enhanced, thanks am trying to get battery out its called AliveCor 2 square metal sensors, black plastic behind and in middle, am trying to find opening for the battery now

I've changed my battery and my AliveCor is still not working. I've lost the paperwork, does anybody know who could have a look at it for me please?

Contact the Kardia help line after you check the battery is in the correct way, the electrodes are not damaged, try using an alcohol gel to improve contact and the signal strength is strong between the Kardia and device you are using.

Unless you send it back to them I am not sure there is anyone you can take it to to look at - most people have never come across one. Representatives are often present at AF Patient Days - but the next one isn't until October.

One other thought - which device are you using and does the app need updating or the OS?

[JackyMac in reply to CDreamer]

Thanks CDreamer, I'll check out your advice.

[Polski in reply to CDreamer]

OS means?!

[CDreamer in reply to Polski]

Operating System

[leahfreilich]

which part comes away? the whole metal electrodes or just the part holding the battery?

im worried i won't get it back on
