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.

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).

ALL All data from Program to Equation Program Program data Editor File names and file data Function Memory Function memory contents Matrix Matrix memory contents Statistics Single-variable and paired-variable statistical data Variable Memory Value memory and extended memory contents Range Graph range parameters Factor Factor function zoom ratios Table Table & Graph function data Graph Function Graph functions, graph draw/non-draw specifica-
tion, graph color specification. Dynamic Graph Dynamic Graph function data Equation Equation coefficients Back Up All memory contents, including mode settings
Note
• If the selections you make on the send unit and receive unit do not match, a TRANSMIT ERROR will be generated on the sender and a RECEIVE ERROR will be generated on the receiver.
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.

COMMUNICATION COMPLETE ALL DATA
PRESS [ AC ]
* Pressing AC interrupts the receive operation and
returns to the LINK Mode.
The following appears after the receive operation is complete.
* Press AC to return to the LINK Mode.
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.
