Hi there and welcome
Do you mean it now has a short battery life Karen? Or it will not turn on at all?
Even with the charger connected?
ok, you have this model. How old is it?
as the batteries will go generally at least 9 months so want to see if they can actually be flat
ok, I just needed to check it was not another issue.
You need the two CR1632 batteries. which you get here
Then to replace
It will then operate again
NOTE: Do not damage or lose the gasket.
The device key on the module must be aligned with the key on the band.
If you would like any additional information or assistance, please do not hesitate to let me know.
