proper range for the system.
Refer to the test strip package insert for
system operating conditions. Move to an
area with the appropriate conditions and
repeat the blood glucose or control test.
Do not artificially heat or cool the meter.
The batteries may be out of power.
Turn the meter back on. If you are in a
cold environment, move to a location
with a more moderate temperature
and retest. If the message continues to
appear after several attempts, replace
the batteries. If the message reappears
after the batteries have been replaced,
remove the batteries, press and hold the
Power/Set/OK button for at least 2
seconds, then reinsert the batteries.
