Meter uses two 1.5V AAA batteries.
When the battery icon (
) is blinking, it means the meter battery is running
low. You should replace the battery as soon as possible. An “E-6” error message
will appear if the battery is too low to perform any more blood glucose tests. The
meter will not function until the battery is replaced.
Instructions:
1. Turn the meter off before removing the battery.
2. Turn the meter over. And then slide the battery cover in the direction of the arrow
to open it.
3. Remove and discard the old battery. Insert two new 1.5V AAA batteries in the
battery carrier.
4. Close the battery cover and make sure that it snaps shut.
5. Recheck and reset the clock setting after battery replacement if necessary. To
set the meter clock, see
