TO REPLACE THE BATTERY
A) To replace the main batteries
Before replacing the main batteries, note the following precautions.
• Do not remove the back-up battery from the SF Unit while main batteries are removed.
• Be sure to replace both batteries at the same time, and do not use an old battery with a new
one.
1. Remove the screw that hold the battery compartment cover in
place.
2. Remove the battery compartment cover by sliding it in the
direction indicated by the arrow in the illustation.
3. Slide the main battery holder in the direction indicated by the
arrow.
4. Remove both old batteries and replace with two new ones.
• Use two new batteries. Wipe the surfaces of the batteries with a
soft, dry cloth. Make sure that the positive (+) sides of the
batteries are facing up (so you can view the positive sides as the
batteries lie in the battery compartment).
5. Replace the battery holder.
6. Replace the battery compartment cover and fasten it in place
using the screw.
B) To replace the back-up battery
Before replacing the back-up battery, note the following precautions:
• Do not remove the main batteries from the SF Unit while back-up battery is removed.
• Be sure to replace the back-up battery at least once a year.

Remove the battery compartment cover by sliding it in the
direction indicated by the arrow in the illustration.
First , remove this sticker from the back-up battery holder.
After removing this sticker, take the screw off that secures the
back-up battery holder in place, and then remove the battery
holder.
Remove the old battery and replace it with a new one.
• Wipe the surfaces of the battery with a soft, dry cloth.
Make sure that the positive (+) side of the battery is facing up (so
you can view the positive side as the battery lies in the battery
compartment.)

TO SAVE THE DATA TO OTHER MACHINE
SF-8350R can transfer customers data to other SF-8350R with memory protection only when replacing
the LCD or the outer case. How to transfer the data.
* Before connecting the cable (SB-60 or SB-62), be sure to reset the slave machine to clear all
data.
Important!
* You can not perform data communications with the CASIO SF-A series of SF Units (SF-A10,etc.).
* Be sure to replace the connector covers on the SF units when you are not performing data communications.
1) Turn off the power switch and connect the two units using the cable (SB-60 or SB-62) as shown in
the drawing.
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

The IC SC371015FU is power supply chip for SF8350. When IC SC371015FU receives a Voltage
6V (CR-2032 × 2 pcs.) at the terminal VDD1(Pin
No.2), the regulated voltage VDD (4.3~4.7V) will
be applied to the VDD lines. The outputs Vss
(VREG) and V1~V4 are the LCD drive voltages.
When the terminal PDB becomes "H", those voltages are generated by IC SC371015FU and capacitors C7 and C8 (ESCT1AY335R) and applied
to LCD driver IC MSM6385AV-Z-358B.
The resistors R8~R10 are used for dividing voltage V1~V4.

2) Gate array
When VDD is applied from power supply IC
SC371015FU to gate array uPD65005G-45222, gate array will send "L" signal to active the
main switch signal from terminal SWO. Also,
gate array will send "H" signal to release the
INT0 terminal of CPU from LSO terminal.
The terminal CSB is for the chip select of gate
array. This signal is sent from CPU terminal
CS2. And when the VDD is applied to CPU,
CPU will send "H" signal to CSB terminal.

EXECUTING !
The TEL to SCHEDULE keys are used to select mode; the
CALENDAR, HOME TIME and WORLD TIME key are used
to set the transmission paraments. The three charactors that
appear on the right side at display represent the parameter.
In the case of the exampledisplay, it indicates 7 BIT, NON
PARITY, 9600 BPS. The operation continues until stopped by
pressing the ESC key and then pressing the ON key for all
modes.
DISP CHNG key : Return to menu mode
TEL key
: Transmission mode. The data of transmission
is "H" and it is sent out by the data of &H34 and
&H38 by the Xon/Xoff control.
Business card key : Reception mode. Make sure to set the
parameter to match that of the transitting side.
The data received appears on the display.
MEMO key : Loop back test. Short the Tx and Rx terminals
for this test. Transmit and check from &H20 to
&H7E. When complete, the message 'CHECK
COMPLETE' is displayed.
SCHEDULE key : output the following ASCII code by Xon/
Xoff control.
!"#*+,-/0123456789:
ABCDEFGHIJKLMNOPQRSTUVWXYZ
abcdefghijklmnopqrstuvwxyz
A line end code is added with each line.
CALENDAR key : Switch the data length 7 bit(7) or 8 bit(8)
HOME TIME key : Switch the parity bit : NON(N)—EVEN(E) —NON(N) —ODD(O)
WORLD TIME key : Switch the transmission speed : 9600(9)—4800(4)—2400(2)—1200(1)
To communicate two machines, please set the transmission machine before setting the receiving unit.
To release communication, press ESC button. In this case, the break code is sent to receive units.
Therefore, both machines display "TRNS BREAK !" and communication will be stopped. Also, if the error
is occurred, both machines display "TRNS ERROR !" and communication will be sttoped.

NOTE : As diagnostic program area does not have all ASCII code, to display a reception data, some
charactor will be changed to other charactor. For example, a chapital letter will be changed
to small letter.

7. Btattery level check
Memory back up battery
The memory back up voltage detector detects any
irregularity in voltage, the machine goes into an
error state and the display is as shown at left figure.
To release this display, press any key.
LOW BATTERY!
BACK UP
Main battery
When the main battery voltage detector detects
low battery condition while display is on, the machine shows the message as shown at left figure.
When this message is displayed, only ON/OFF
key are possible to operate. And if the voltage
becomes lower than 4.4V, the display will be off
mode (auto power off mode).
LOW BATTERY!
8. Others
1) When power is off after presetting a alarm time, automatically power is on at a alarm time.
However, the display is not reserved in this case.
2) When executing memory sum check, before execute the RAM write check (with TEL button).
3) To release diagnostic mode, press reset button.
4) The display contrast can be changed by the contrast volume.
