REPLACING THE BATTERIES

Loosen the screw on the back of the SF-5300B that
holds the battery compartment cover in place, and
remove the cover.

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.

Replace the old battery with a new one. Be sure that
the positive (+) side of the new battery is facing up (so
you can see it).

Replace the battery holder and secure it by tightening its screw.
• Be careful that you do not overtighten the screw.

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.

After you replace both batteries, replace the battery compartment cover and secure it by tightening
its screw.
• Be careful that you do not overtighten the screw.
