Replacing the Battery
Your On Call
®
Extra Meter uses one 3.0 Volt CR 2032 lithium battery.
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 one new CR 2032 3.0 V coin cell
battery in the battery carrier. Make sure the plus (+) side is facing up.
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 Meter Setup Before Testing on page 12.
