SOURCE: Need to change tax function on Sharp EL-334A

I had the same problem and finally figured it out. Here's what you do:

Press C-CE twice
Press +TAX (Rate set)
Key in your new tax rate as an integer (e.g. 5)
Press +Tax (Rate set) again
Press C-CE

Then you're ready to calculate with the new rate!

Now what's the GT button for?

SHARP EL-1801V DON'T KNOW HOW TO SET THE DATE AND TIME

Posted on Jun 12, 2008

SOURCE: EL 1801V - how to set time/date?

To change the date, enter the date in MM.DD.YY format, pressing the decimal key between the month and day (will show as a decimal on the display) and the day and year (will show as a dash on the display). Then, press the Time/Date key (the one that looks like a clock and a calendar). The new date will show on the display. Note that if the month is less than 10, you do need to press the 0 (zero) key for the first digit, even though it will not show on the display. To change the time, enter the time in 24-hour HH.MM format, pressing the decimal key between the hour and minute. Then, press the Time/Date key. The new time will show on the display. Note that if the hour is less than 10, you do need to press the 0 (zero) key for the first digit, even though it will not show on the display. Hope this helps! :)

Check the Decimal / Add Selector. It shoul be set to "A" (Add mode), to permit addition and subtraction of numbers without entry of the decimal point.

Just reset mine and is current. If the built in battery needs changed, access panel is on the back. It uses a watch type battery.
