TO REPLACE THE BATTERIES
Screw
1) Loosen the screw on the back of the SF-4300B that
holds the battery compartment cover in place, and
remove the cover.
2)
Loosen the screw that secures one of the two battery
holders in place and remove the battery holder.
RESET
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 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 two batteries. Never mix old batteries with new ones, and be sure to use
CR2032 lithium batteries only.
6)
After you replace all two batteries, replace the battery compartment cover and secure it by tightening
its screw.
• Be careful that you do not over tighten the screw.

DATA TRANSFER
SF-4300B can transfer customers data to other SF-4300B with memory protection only when replacing
the LCD or the outer case. How to transfer the data.
* Before connecting the cable (SB-60/62), be sure to reset the slave machine to clear all data.
1)
Turn off the power switch and connect the two units using the cable (SB-60/62) as shown in the
drawing.
SB-60/62 accessory cable
2)
Turn on the power switch of each machine.
3)
The slave machine must be set the date of Feb. 3rd, 1901 into the memory under the calculator mode.
Operation: 1. Press ON MENU
2. Select "CAL" mode or press 6.

Setting up for Data Communications
The following procedures describe what you should do to set up for data communications between
two SF Units or between an SF Unit and a personal computer. In addition to hardware connections,
it details how to set up the communications parameters and how to set up the SF-4300B to receive
data. By following these instructions carefully, you can be ensured of successful communications
every time.
To connect two SF Units
1.
2.
3.
Check to make sure that the power of the two SF Units is switched off.
Remove the covers from the connectors on the two SF Units.
Connect the two SF Units using the optional SB-60/62 cable. You can also connect them using
an SB-60/62 cable.
Important
Be sure to replace the connector covers on the SF Units when you are not performing data
communications.
4)
Check the hardware parameters.
