When
battry
appears on the display, the Meter
will no longer give results and you
must replace the battery before you
can perform another test.
A dead battery or battery removal
will not affect the previous test
result stored in the Meter's memory,
as long as the battery is replaced
within 30 days.
Replacing the battery
Make sure the Meter is turned off
before you remove the battery.
Turn the Meter upside down. With
your thumb, firmly press in and up
on the ridges on the side of the
battery door until the door releases
from the clasp. Remove the battery
door by sliding it out.
