    My calculator was working fine and then all of the sudden none of the buttons work except for the on button. It won't turn off until it auto shuts down, and the number buttons do not work. I just have a flashing square at the top.

My Electronic crossword puzzles by RadioShack comes on but will not do anything. I just put in new batteries. I do not have my manual.


Adjusting The Display

To increase or decrease the display's contrast so it is easier to read,
hold down FUNCTION, then press /\ or \/ on the cursor pad.

Playing The Game

1. Press ON/OFF to turn on the game.

If you have not worked a puzzle since installing or replacing the
batteries, CROSSWORD MASTER appears. Otherwise, the display is as it
was when the game was turned off.

2. To start a new puzzle at any time, press FUNCTION and 1 (I), 2 (O), or
3 (P) at the same time. 1 is for beginner-type games, and 2 and 3
increase in difficulty. NEW GAME LEVEL 1, 2, OR 3 Y/N appears.

3. Press Y to start a new puzzle. A crossword grid with flashing cursor
appears (O).

Otherwise, press N. The display appears as it was when you pressed
FUNCTION and 1, 2, or 3.

4. Press (or hold down) /\, \/, <, or > on the cursor pad to move the
cursor around the puzzle.

5. With the flashing cursor in the desired location, press ? to see the
clue(s) for the word(s) in that location.

Any letters you already entered appear, along with a dash for each
missing letter. The number of letters appears in parentheses - for
example, (5) for a solution with 5 letters. If the solution includes
more than one word, the number of letters for each word appears in the
format - for example, (5, 3, 4) for a solution with three words.

If the flashing cursor appears at the junction of two words (across
and down), both clues appear, across first, then down.

6. Press ? again to return to the crossword display, then use the letter
keys to type your answer.

If the flashing cursor was at the junction of two words and you enter
the first letter of your answer, two small arrows appear in the
adjacent across and down squares. Before typing the rest of your
answer, press > or \/ (across or down) on the cursor pad to indicate
which word you are entering.

Press /\ on the keyboard to erase the letter just above, and < to
erase the letter to the left of, the flashing cursor.

To erase a word, hold down FUNCTION and press WORD DELETE (Z).

To spell check the puzzle at any time, hold down FUNCTION and press
SPELL (T). The [+] symbol indicates the location of each incorrect
letter.

When you complete a crossword correctly, GAME COMPLETED appears.

7. Press ON/OFF to turn off the game. The current puzzle is saved.

Entering waypoints manually


Notice that when you pull up the MARKed coordinates the yellow cursor is on the N/S letter rather than the number. Since a number is impossible there it won't let you enter one.

Use the rocker to move to the popup screens directional arrows to move to the digit you want to change. This will be easiest with the the RIGHT arrow at first; once you see the cursor it will make sense. Note I am talking about the popup's RIGHT square and not the rocker's RIGHT direction.

Nintendo DS Lite keyboard problem


Recalibrating the Touch Screen
Remove all games from the Nintendo DS Lite.
Turn the system on by pressing the POWER switch.
Press the A Button when the "Touch the Touch Screen to continue" message appears.
When the main menu appears, use the Control Pad to place the cursor over the Settings Menu Panel at the bottom of the screen, and press the A Button.
Use the Control Pad to place the cursor over the orange icon that looks like crosshairs (the right-most icon), and press the A Button.
Use the stylus, and tap the red square that appears on the screen. Do this each time the square moves. (Note : You must touch the red square precisely at each of the three positions, otherwise the test will continue to re-start.)
When complete, four squares will appear, allowing users to test the touch screen sensitivity. (Testing is optional.) Tap the "Confirm" button in the lower-right corner.

Wait for the the confirmation message to disappear, then tap "Quit," then "Yes" to exit. The unit will shut down automatically to save the settings.

Changing the Cursor Appearance


I had this same problem on my TI 89... You must have accidentally set your calculator to insert mode. To switch it back to the thin cursor, input the following keystrokes... Go to the "2nd" key to enter second function mode. Then press the button with an arrow on it pointing to the left(The key that you use to backspace). Do you see the "INS" lettering above the backspace key? There's your solution :-)

I have a brother 4100 fax. how do I change the information on the fax transmission page? thank you


If your date and time are not set yet, press Menu, then 1, then 2 and enter the date and time, pressing Set after each entry. Enter time in 24-hour format so it will display AM or PM properly.

For other info at the top of your fax transmission page after date and time, such as your fax and phone numbers, and company name:
Press Menu, then 1, then 3 for Station ID info.
First put in your fax number and press Set.
Next put in your phone number and press Set.
Next press the buttons for your company name and press Set.
Press Stop/Exit to return to the date and time display.

Here is info on inputting text, from the manual:
Entering Text
When you are setting certain functions, such as the Station ID, you may need to type text into the machine. Most keys on the dial pad have three or four letters rinted above them. The keys for 0, # and don’t have printed letters because they are used for special characters.
By pressing the appropriate number key repeatedly you can access the character you want.
Inserting Spaces
If you want to enter a blank space, press once between numbers and twice between characters.
Making Corrections
If you entered a letter incorrectly and want to change it, press to move the cursor after the last correct letter. Then press Clear; all letters above and to the right of the cursor will be deleted. Re-enter the correct characters. Also, you can back up and type over incorrect letters.
Repeating Letters
If you need to enter a character that is assigned to the same key as the previous character, press to move the cursor to the right.
Special Characters and Symbols
Key - once - twice - three times - four times - five times
