Nothing happens when I press a number??

My Sharp EL-531-WH display has a 'P' next to the '0'. I press a number and nothing shows on the display. Is there a lock button or something I have to press to unlock it??

Hello,
There is no lock button. Calculator may be configured to be in computational mode you are not familiar with: It may be set to do base calculation on base 5, hence the p (pental). Press the reset button on the back, and the default configuraion will be restored.
You should give some time to learn the different mode of calculations.
Hope it helps.

Showing a small p next to 0 and wont let me enter numbers 5-9


Your calculator is set to pental (base 5) where only the digits 0 through 4 are valid. See [9] on page 3 of the manual: http://www.fixya.com/support/p3185467-sharp_el_531x_scientific_calculator_gree/usermanual-DBA930D-pdf

To switch to decimal, press 2ndF -DEC.

My calculator will show fractions instead of decimals when doing division. How do I change that? There is a N1 displayed in the lower left corner also...I think that may be the problem


Getting Decimal Answers by Disabling WriteViewelw516.gif on the Sharp EL-W516 Calculator

The Sharp EL-W516's WriteView display uses multiple lines to display mathematics as it is seen on a page. Fractions are shown as fractions, exponents as exponents, integrals as integrals, and so on. This makes entering calculations easier, and reduces the chance of errors.

At the same time, calculation results are displayed as fractions (or with roots or pi) whenever possible. Pressing the CHANGE button repeatedly will change these to decimal answers.
If you prefer to always get decimal results you need to disable the WriteView display mode. Doing this will make the calculator display like the Sharp EL-546W when in NORMAL mode. Answers will be given as decimals, but fractions will no longer look like fractions. In general, you will still need to follow the EL-W516 instructions.
Disabling WriteView

Press 2ndF and MATH to enter SET UP. Now press 2 for EDITOR.

There are now two options: 0: W-VIEW, and 1: LINE

Press 1 for Linear display mode to disable the WriteView display, and to get decimals as your answers.

To return to the WriteView display, go through the steps above but press 0 for W-VIEW.

NOTE: It is not possible to have decimals as the default answer form when in WriteView mode.

You can access the .pdf manual for your particular calculator here:

Page 1 for how to set date/time:

“RATE SET”: To set the date, time, and tax rate, set this switch at the “RATE SET” position.
Date:
• Enter in the order of month, day and year, then press to complete the entry.
• Use to separate month, day, and year.
• When is pressed, the number entered is evaluated and displayed as “date” if the
value is within the following range; “Error” is displayed otherwise, and the previously set
date is restored.
Month: 1 - 12; day: 1 - 31; Year: 2000 - 2099 (in 4 digits) or 00 - 99 (in 2 digits)
Time:
• Enter in the order of hour, minutes, then press to complete the entry.
(There is no entry available for the seconds value. The clock starts at zero second.)
• If the hour/minute digit is less than 10, it is not necessary to enter the first digit “0”.

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! :)
