3-4. About Low Battery Warning
If the following message appears on the display, immediately stop using the calculator and replace
batteries.
✽✽ Low battery! ✽✽
If you try to continue using the calculator, it will automatically switch power off, in order to protect
memory contents. You will not be able to switch power back on until you replace batteries.
Be sure to replace batteries at least once every two years, no matter how much you use the calculator during that time.
4.REPLACING BATTERIES
Warning!
If you remove both the main power supply and the memory back up batteries at the same time, all
memory contents will be erased.
— 6 —
Precautions:
Incorrectly using batteries can cause them to burst or leak, possibly damaging the interior of the
unit. Note the following precautions:
• Be sure that the positive + and negative - poles of each battery are facing in the proper direc-
tions.
• Never mix batteries of different types.
• Never mix old batteries and new ones.
• Never leave dead batteries in the battery compartment.
• Remove the batteries if you do not plan to use the unit for long periods.
• Never try to recharge the batteries supplied with the unit.
• Do not expose batteries to direct heat, let them become shorted, or try to take them apart.
4-1. To Replace the Main Power Supply Batteries
* Never remove the main power supply and the memory back up batteries from the unit at the same
time.
* Be sure to switch the unit off before replacing batteries. Replacing batteries with power on will
cause data in memory to be deleted.
* Never replace the main power supply battery compartment cover or switch the calculator on while
the main power supply batteries are removed from the calculator or not loaded correctly. Doing so
can cause memory data to be deleted and malfunction of the calculator. If mishandling of batteries causes such problems, correctly load batteries and then perform the RESET operation to
resume normal operation.
* Be sure to replace all two batteries with new ones.
1 Switch the power of the calculator off, and slide the calcula-
tor into its hard case.
2 Remove screw A on the back of the calculator, and remove
the main battery compartment cover.
3 Remove the two old batteries.
4 Load a new set of two batteries, making sure that their
positive + and negative - ends are facing in the proper
directions.
5 Insert the tabs of the main battery compartment cover into
the slots in the back of the calculator and replace the cover.
Secure it in place with the screw.

* Before replacing the memory backup battery, switch on the unit and check to see if the "Low
battery!" message appears on the display. If it does, replace the main power supply batteries
before replacing the back up power supply battery.
* Never remove the main power supply and the memory back up batteries from the unit at the same
time.
* Be sure to switch the unit off before replacing batteries. Replacing batteries with power on will
cause data in memory to be deleted.
* Be sure to replace the back up power supply battery at least once 2 years, regardless of how
much you use the unit during that time. Failure to do so can cause data in memory to be deleted.
1 Switch the power of the calculator off.
2 Remove screw B on the back of the calculator, and remove
the back-up battery compartment cover.
3 Remove the old battery.
4 Wipe off the surfaces of a new battery with a soft, dry cloth.
Load it into the calculator so that its positive + side is
facing up.
5 Insert the tabs of the back-up battery compartment cover
into the slots in the back of the calculator and replace the
cover. Secure it in place with the screw.

5.RESET OPERATION
Warning!
The procedure described here clears all memory contents. Never perform this operation unless you
want to totally clear the memory of the calculator.
You should perform the RESET operation whenever you want to initialize the calculator. If you need
the data currently stored in memory, be sure to write it down somewhere before performing the
RESET operation.

you accidently delete it using the RESET operation.
• If the calculator stops operating correctly for some reason, use a
thin, pointed object to press the RESET button on the back of the
calculator. This should make the RESET confirmation screen
appear on the display. Perform the procedure described above to

6.WELDING CONDITION FOR THE CERAMIC OSCILLATOR (CSTC4.30MG-TC)
Because the heat-resisting test for welding the ceramic oscillator (CSTC4.30MG-TC) was administered by factory under the condition that weld temperature was 240 ± 5 °C and welding time was 3 ±
1 seconds after the preheating of 150 ± 30 °C temperature and 60 seconds time, it is recommended
that you should give first priority to take the welding condition, 150 ± 30 °C and 60 seconds for
preheating, and 230 ± 5 °C and less 20 seconds for welding, if you have to weld the ceramic oscillator (CSTC4.30MG-TC).

• Though you can transfer programs between the CFX-9800G and another CFX-9800G, an fx7700GB, an fx-7700GE an fx-7700GH, an fx-9700GE, an fx-9700GH, an OH-7700GE, an OH9700GE or an fx-8700GB, all of the examples in this manual cover data transfer with another
CFX-9800G only.
11-1. Connecting Two CFX-9800G Units
The following procedure describes how to connect two Power Graphic units with an optional SB-62
connecting cable for transfer of programs between them.
To Connect Two CFX-9800G Units
1. Check to make sure that the power of both CFX-9800G units is off.
2. Remove the covers from the connectors of the two Power Graphic units.
• Be sure you keep the connector covers in a safe place so you can replace them after you
finish your program communications.
3. Connect the two units using the SB-62 cable.
SB-62 cable
Important
• Keep the connectors of the CFX-9800G covered when you are not using them.
11-2. Before Starting Data Communications
Before actually starting data communications, you should first enter the LINK Mode from the Main
Menu.
To Enter the LINK Mode
Highlight the LINK icon on the Main Menu.
Press
The following are the operations that can be selected from the function menu at the bottom of the
display. Press the function key below the operation you want to perform.

11-3. Setting Communications Parameters
Before you can perform data communications, you must first set up certain hardware parameters to
make sure that the two units are able to understand each other. The parameters of the sender and
the receiver must be identical for them to be able to communicate correctly. There are two hardware
parameters that you can set.

Warning!
Transferring data using ALL causes data in the applicable memory areas of the receiving unit to be
replaced by the received data. Make sure that you do not need the data stored in the receiving unit
before you start an operation using ALL.
11-5. Data Communications Precautions
Note the following precautions whenever you perform data communications.
• A TRANSMIT ERROR occurs whenever you try to send data to a receiving unit that is not yet
standing by to receive data. When this happens, press AC to clear the error and try again, after
setting up the receiving unit to receive data.
• A RECEIVING ERROR occurs whenever the receiving unit does not receive any data approximately six minutes after it is set up to receive data. When this happens, press AC to clear the
error.
• A TRANSMIT ERROR or RECEIVE ERROR occurs during data communications if the cable
becomes disconnected, if the parameters of the two units do not match, or if any other communications problem occurs. When this happens, press AC to clear the error and correct the problem
before trying data communications again. In this case, any data received before the problem
occurred is cleared from the receiving unit's memory.
• A MEMORY FULL operation occurs if the receiving unit memory becomes full during data communications. When this happens, press AC to clear the error and delete unneeded data from the
receiving unit to make room for the new data, and then try again.
