Press the reset button on the back of the unit. As to the things you want to get rid off, if they are on the top of the screen, they are indicators, to let you see what mode you are using. Some will change when you chande operation mode. There is nothing you can do about it.
However if these symbols are in the center of screen , with numbers to there left (a different number for each) they may be part of the setup procedure. During the setup procedure you are expected to configure your calculator in the mode relevant to the calculations you intend to perform.
What is an upside down p ? Could it be just a b? (as in binary). That is a mode of operation.
Hope it helps.

I have fix and deg on my fx 992s and I am only getting results and can only enter numbers to 1 dp. How do I remove this?

Ok. Press [MODE] key three times until you see a screen that shows Fix SCI and NORM. Under FIX you have 1, under SCI you have 2 and under NORM you have 3.

You cannot remove FIX, unless you replace it with another display MODE (SCI or NORM or ENGineering).

You cannot remove DEG unless you change angle unit to RADians or GRAds.
To set angle Unit You start by pressing MODE twice to get a screen that displays DEG, RAD and GRA and below them 1, 2 , qnd 3. If you press 2 the angle unit will be set to Radians. DEG will disappear, but RAD will be shown.

Whatever the display format for numbers (FIX, SCI, NORM, ENG) you can always enter numbers of any length. It is their displaying that is affected by the FIX,SCI, etc. mode.

If you want more than 1 decimal digit, press [MODE] three times, then select 1: FIX. You will be asked to select the number of decimal digits (from 0 to 9). You could take 2, 3 or 4, or anything you want.

  1. To summarize: Indicators on screen reflect the configuration or mode you are in.
  2. They can be replaced by others but you cannot clear the screen of the indicators.
  3. You can select the number of decimal digits in your results,
  4. but there is no restriction on the numbers you enter.

My LG Chocolate VX8550's LCD screen decided it would like to turn upside down permanently, and I don't know how to right it. It's rather hard reading or typing upside down, so does anyone know how to...

Well.. Umm.. Do you know how it could of been turned upside down?
Well you could try going to SETTINGS and then to SECURTIY and from there you could try RESTORING IT. Now, i don't know if this will fix your problem... But it MIGHT work.

PLEASE NOTE: When restoring your phone, you put it back to the factory settings
