3. TO REPLACE THE BATTERY
To replace the batteries
1. Loosen the screw on the back of the SF Unit that holds the battery compartment cover
in place, and remove the cover.
Caution
In the next step, be sure to remove only one battery at a time.
Otherwise, you will lose all data stored in memory.
2. Loosen the screw that secures one of the three battery holders
in place and remove the battery holder.
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 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.
