Question about Logitech Cordless Desktop Wave Keyboard and Mouse

For example. When I type in the qustion mark ? is will change to an E with an\ above the E. The same quite often happens when I type the @ it will show a Explanation mark !.

I checked all the instructions, checked the Logitech website troubleshooting, but could not find the answer.

would you know why this happens. When I restart the computer it will correct itself for a little while, but then for no reason at all, it will do it again, espcially those 2 keys.

I should take the keyboard back to the retails store, but it is very difficult for me at this time to leave my husband on his own.

I hope you will have a solution.

Thank you very much.

First, make sure you have the appropriate angular mode set. To change the angular mode, press MODE, use the arrow keys to highlight either "RADIAN" or "DEGREE" on the third line, press ENTER, then press 2ND [QUIT].

Press the appropriate sin, cos, or tan key (two rows above the 7, 8, and 9 keys), enter the angle, close the parenthesis, and press ENTER. For example, to calculate the sin of 2.1, press

SIN 2 . 1 ) ENTER

Try the shift key. Hold it down first then press the number key with the symbol you want to type.

Assuming you already have Swype installed, you need to activate it first by going to Menu -> Settings, Language & Keyboard, then putting a check mark next to Swype (you will get a warning which you can disregard). Then go to a text field and long press the empty area (for example, long-press in the field where you would type in a SMS message), then hit Input Method. You should see a menu pop up, simply click Swype and you should be ready to go.

2 to the 10th power

Aug 31, 2010 | Texas Instruments TI-30XA Calculator

Use the log function (common logarithm). See screen capture for markings
on key.

To evaluate the negative of a logarithm

Enter the number (argument) of the logarithm

Press the = key to have it calculated.

While result is still displayed, press the sign change key or (+/-).

Beware that -log(number) is not necessarily a negative value.

Another way to calculate -log is to use the relation

log(1/a)=-log(a) .

Your example

3 [EXP] [(] [+/-] 2 [) ] [LOG][=] [+/-]

[EXP] is the key to enter exponent of a power of 10 :It is a shortcut, so no 10 is entered. Respect the key sequence above.

[ (] left parenthesis to prevent ambiguity due to the negaticve exponent. Just a security.

[)] is the enclosing right parenthesis

[+/-] is the Sign Change key

- Use the universal power key marked with [^].
- To avoid problems if the exponent is an expression, enclose it in parentheses.
- To enter any power type number^(exponent)
- If exponent is negative use the (-) change sign key next to the dot, below the 3 key.
- To calculate the roots (cubic, fourth, fifth, etc.) roots use the fact that a root of n-th order can be represented as ^(1/n)
- Ex: cube root of 27: 27^(1/3); square root of 64 : 64^(1/2) or 64^(0.5)

If your calculator is not working and have an internet connection in your home, you can use Google search page as a calculator or else you can search for online calculators.In the Google search page you can directly type for example -- 2+3 and then hit enter you can get the result on the page.
