When
BATTRY` REPLACE NOW
appears flashing on
the display, the meter will no longer give results and you must replace the batter- ies before you can perform another test.
Dead batteries or battery removal will not affect the information stored in the meter memory. The time and date will be saved in the meter for approximately an hour without the batteries.
Step 1: Turn the meter over and locate the battery compartment door.
Make sure the meter is turned off before you remove the batteries.
Step 2: Remove the battery compart- ment door.
Turn the meter 
over so that the 
front is resting in the palm of your hand. With your thumb, press upward on the opening tab 
of the battery 
compartment door 
and lift upward until it releases
from the clasp.
