Hi,

I have this calculator.
I haven't got batteries yet, but I have the manual.
These are the instruction for resetting:

1. Press the RESET button on the back of the calculator with a thin,
pointed object.

2. When a data item is stored in the secret area, the message "SCRT RESET?" appears on the display to confirm whether or not you actually wish to perform the Secret Reset procedure.
Press the SET key to proceed with the Secret Reset.

3. The message "SCRT RESET !" appears on the display for a short while to indicate that reset is complete, and then "0." appears to indicate that the secret area data and password have been deleted.

4. Press the RESET button and the message "RESET ?" appears on the display to confirm whether or not you actually wish to perform the Reset procedure.
Press the SET key to proceed with the Reset.

Hope this helps.

David.

Sorry to say it but the DMS key is to convert between Degrees, minutes, seconds and decimal degrees (angle units). This cleared here is how to use the DMS key on this calculator.

Label of key [deg symbol ' "]. It is between [(-)] and [hyp]

To enter a value in decimal degrees
12.58 [deg ' "] [=] Screen displays 12.58 deg on top line and 12 deg 34' 48" on bottom line.
Pressing the [deg ' "] key while this value is displayed will show 12.58

To enter a DMS value:

Press the [deg ' "] key after each number even if one of the numbers D,M,S is nill (0).
Exemple Enter 25 deg 0 ' 48"
25 [deg ' "] 0 [deg ' "] 48 [deg ' "] [=]
Screen displays 25 deg 0' 48" on bottom line
Pressing the [deg ' "] key converts this result to decimal degrees 25.013

Okay, so I've got a fx-7400G PLUS. My stupid friend put the contrast to light and turn it off. The calculator stop working. What can I do to make it work again? Thanks in advance.


Hi,
Reset the calculator. On the back of the calculator there is a reset button (Above battery compartment and to the left. Use a thin pointed object to push it. The calculator will ask for confirmation to reset all memory back to default. Press [F1] to accept.
And next time avoid hanging out with stupid people, and don't lend them your calculator. Didn't you know that stupidity is contagious?

Hope that helps.
Thank you using FixYa and for rating this solution.
