DEG mode Can't remove the DEG mode to work on division problem.

On the 30Xa, press the DRG key to cycle through the different angular modes. Be aware that no matter what mode you set, the display will show an indicator of the current mode. You can't remove the indicator completely.

Dear Mahesh

In Cool Mode

Temp Diff - + - 1 deg C in Room Temp & Set Temp

This is auto cut

In Dry Mode

Comp Runs for 10 mins then get off for 5 mins then again get on for 10 mins this cycle continuues.

Check the thermostat setting...in the auto machines, with a reversing valve, there is no heating or cooling, generally, in the sensing temperature band of 19 Deg C to 22 Deg C and it only works on blower mode, re-circulating the room air. When the sensing temperature goes below 17 deg C, it works on heating and when the sensing temperature goes above 24 deg C, it works on cooling

Is there a button marked DEG->? That is the standard calculator button used to change mode. It could possibly be the shift function of another button.

It is either 2nd and pi symbol or 2nd and INT division.

To find the tangent of an angle:

1. input TAN (it's up one and left one from the division key)
2. then the desired angle
3. then a close parenthesis
4. And then hit ENTER

You might have to switch your calculator from radian to degrees or from degrees to radians to get the expected result. To do that:

1. Press MODE
2. Scroll down to where it says ANGLE
3. change it from either RAD or DEG by pressing ENTER

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.
   

The DEG indicator on the screen is a reminder to the user that the ANGLE unit is in degrees. You can change the angle unit to Radian or Grads. That does not have any incidence on other calculations. It only affects the computation of trigonometric functions : sine, cosine, tangent, arc cosine, arc sine and arctangent. So if you have syntax error in the calculation of the interest formula, I can assure you it has NOTHING to do with the angle unit.
I do not see the formula you are trying to use, so I cannot be sure what you are doing wrong.

1. Possible wrong usage of the regular minus sign instead of the change sign (-) or (+/-)
2. Missing right parenthesis
3. A right parenthesis is inserted at the wrong place.
   
4. Incorrect use of the power function

I suggest you write the correct formula on paper and enter it step by step. A step is defined by an operation: multiplication, division, power. Start with the content of parentheses and work toward the outside. The last result is always the one stored in Answer memory (Ans).

I do not think that the DEG and FIX indicators are preventing you from calculating any logarithm. DEG appears to remind you that the CURRENT angle unit is the degree. You can change it to RAD or GRAD if you have to use those units. However, DEG will disappear only if replaced with RAD or GRAD.

The indicator FIX reminds you that the display mode for the results is the FIXed mode, not the SCIentific mode. In the FIX mode you specify the number of decimal digits from 0 to 9 and all your results will show the set number of decimals. So if all your results have a lot of unnecessary 0, maybe you should set the FIX mode to fewer decimal digits.

If you still have a problem with the calculation of logarithms, maybe the syntax you use is incorrect.

Try number then log
If that does not work
try log then number.

Read the screen capture about the MODES of this calculators. DEG,RAD, and GRAD remind the user that the angle units in trigonometric function calculations and coordinate conversions are in degrees, radians or grads. They have nothing to do with the other calculations you are doing.



You can only remove DEG by changing the angle unit to RADians or GRADs. In so doing, the new unit indicator (RAD, GRAD) will be displayed instead. There is no point worrying about the angle unit indicator unless you are performing coordinate conversions or calculating trigonometric functions or the inverse trigonometric functions.

MODE 9 cancels the FIX display format: decimal are displayed with a fixed number of decimal places (set by the user). After this key sequence the decimal display format reverts to NORM(al).
