Otherwise, you will lose all data stored in memory.

3) Replace the old battery with a new one, making

sure that the positive (+) side of the new battery

is facing up (so you can see it).

4) Replace the battery holder and secure it by tightening its screw.

• Be sure careful that you do not over tighten the screw.

5) Repeat steps 2) through 4) for the other two batteries.

• Be sure to replace all three batteries. Never mix old batteries with new ones, and be sure

to use CR2032 lithium batteries only.

6) After you replace all three batteries, replace the battery compartment cover and secure it

by tightening its screw.

• Be careful that you do not over tighten the screw.
