REPLACING THE BATTERIES
1. Loosen the screw on the back of the unit that holds the battery
compartment cover in place, and remove the cover by sliding
it to the direction indicated by the arrow.
2. Loosen the screw that secures one of the two battery holders
in place and remove the battery holder.
Caution: Be sure to remove only one battery at a time.
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 careful that you do not overtighten the screw.
5. Repeat Steps 2 through 4 for the other battery.
• Be sure to replace both batteries. Never mix old batteries
with new ones, and be sure to use CR2032 lithium batteries
only.
6. After you replace both batteries, replace the battery compart-
ment cover and secure it by tightening its screw.
• Be careful that you do not overtighten the screw.
