Notes:
• The meter uses one 3-volt lithium battery, type CR 2032. It is a good idea to have a
spare battery available.
• Be sure the battery goes in + side up or facing you.
• After you change the battery, your meter prompts you to confirm the meter's time and
date settings. All test results remain saved in memory.
