Accu-Chek Performa Nano Owner's Booklet page 62

Notes:
• The meter uses two 3-volt lithium batteries, type 2032. This type of battery can be
found in many stores. It is a good idea to have spare batteries available.
• Be sure the batteries are inserted
• After you change the batteries, the meter prompts you to confirm the meter's time
and date settings. All test results are saved in memory.
• Always replace both batteries at the same time and with the same brand.
