My Accu-Chek Performa-nano meter appears to have given up after two years. It flashed code E7 so I followed the instructions and it died. I tried new batteries and it still stayed dead. Any suggestions welcome. Or is it time to get a new meter? If so recommendations welcome here too - I'm well-controlled type 2 so I only use the meter sporadically. Thanks.
Call the manufacturer and ask for a replacement.
Given they make their money from the test strips, they should be happy to encourage you to continue buying more strips.
