Meter Maintenance and Troubleshooting
Meter Maintenance
The meter automatically tests its own
systems every time you turn it on and lets
you know if something is wrong. See the
Error Messages section in this chapter.
If you drop the meter, or think the results
are not accurate, contact Roche.
w WARNING
Keep new and used batteries away
from children. See the warning in the
Introduction of this User’s Manual for
additional information.
Changing the Batteries
Open the child-resistant battery door by
inserting a narrow object, such as a
pen, into the slot (see image above).
Push the tab in the direction of the
arrow and lift the battery door up.
Remove the old
batteries.
Slide the new batteries
under the black tabs
with the (+) side
facing up.
Put the battery door
back in place and snap it closed.
NOTE
• Always have a spare set of batteries.
• Battery life may vary due to factors
such as temperature and battery
manufacturer.
• If the E-7 or E-9 error code still
appears on the display after you
have changed the batteries, remove
the batteries again, press
for at
least 2 seconds, then reinsert the
batteries.
• The meter uses two 3-volt lithium
batteries, coin cell type CR2032. This
type of battery can be found in many
stores.
• Always replace both batteries at the
same time and with the same brand.
• Meter data is not lost when you
replace the batteries.
Cleaning and Disinfecting the
Meter
Keep the meter free of dust. If you need to
clean or disinfect it, follow these
guidelines carefully to help you get the
best performance possible.
