Meter comes with two
1.5 V (#357 or equivalent) silver oxide batteries that
are already installed. Each pair of batteries will
provide you with enough power to perform about
1,000 tests. When replacing batteries, use only 1.5 V
(#357 or equivalent) silver oxide batteries. Do not use
alkaline batteries in your OneTouch

Meter.
The meter will alert you when the power is getting
low by displaying two different messages:
1. The É symbol appears on the
display with the unit of measurement
when the meter is turned on and all
the other display messages are
functional. From the time the É
symbol first appears, there is enough
power left for about 50 tests. The test
results will be accurate, but it is time
to change the batteries.
