Question about Sharp EL-531VB Calculator
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??
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.
