• Be sure to always keep written copies of all important data in case
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
complete the RESET operation.
• If the RESET confirmation screen does not appear when you press
the RESET button, keep pressing the button until it does.

WELDING CONDITION FOR THE CERAMIC OSCILLATOR (CSTC4.30MG-TC)
Because the heat-resisting test for welding the ceramic oscillator (CSTC4.30MG-TC) was adminis-
tered 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 oscilla-
tor (CSTC4.30MG-TC).
