It happens because some alkaline batteries just don't have the initial surge of power output required to drive all the little motors, the display and so on.

You need lithium batteries, like the 8x Ultimate Lithium.
They are expensive initially, but on average are more economical than the cheaper stuff.

I've tested them on my Kodak Z712 IS, and any owner of this camera knows what I'm talking about.

The best -and cheapest- solution I found, is the rechargeable Li-Ion batteries.
I got 2 batteries and one charger. I'm using one battery, while the other one is charging.

If the quadratic equation has no roots, you cannot find the roots. The discriminate is negative, so if we attempt to use the quadratic equation, we get no roots.

For example, y=x^2 +0x + 3

a=1, b=0, c=3

(-b+/- sqrt(b^2 -4ac))/2a

Substituting in the numbers, we get

x= (-0 +/-sqrt(0^2 - 4(1)3))/2
x= (0 +/- sqrt (-12))/2

We cannot do the square root of -12. Therefore, there are no roots. This is the same as having no x-intercepts. The discriminant is b^2-4ac. In this case it is -12. Thus, there are no real roots.

However, you can still determine the maximum or minimum, the vertex, the axis of symmetry, the y-intercept and the stretch/compression. With this information you can graph the equation.

In this case, the y-intercept is 3, the vertex is at (0,3), the axis of symmetry is x=0, the minimum value of the function is 3.

Good luck.

Let me know if you have any questions.

Because it is damaged, broken or otherwise rendered incapable of functioning.

It needs repairing.

This doesn't answer your question directly but may help if you decide to get another pedal.
I had a Casio keyboard for a while, and found that the polarity of the sustain pedal was the reverse of that on most other makes. This meant that when I bought another pedal (not Casio), it sustained when not depressed, and did not when depressed. To correct this all I did was to cut the cable near the pedal, reverse the wires, solder them back and cover with nice electrical tape.

By the way if you use SEABOARD or MAINSTAGE then there's a different trick (avoiding cutting wires) on this link:

If this wasn't completely useless then please give this a good mark! Thanks.

Hi.
This is very serious. It means the register is about to completely clear everything (or may have done so already). If it has been sitting for a long time without power, or new out of the box, then this is normal. We can try to jump it back out of the init mode.

Turn the power off at the wall.
Turn the key to PROGRAM mode.
Hold RECEIPT FEED button down.
Turn power on at wall.
When you see the display change to 'FFFFFFFFFF' let go of RECEIPT FEED.
Press SUBTOTAL

Turn the key back to REG mode and try it. If you get error 8, then you may need to log a clerk back on.

Let me know if you have problems.

This error occurs when you turn the key when you have not completed a sale or x/z reading.

Turn key to last know position hit Subtotal or Cash to complete.

To calculate the square root use the square root key, three rows above the "8" key.
If you want to see the result symbolically, press SHIFT MODE 1 to select the MthIO mode. Bear in mind that the calculator can only show some results symbolically.

This may have a reset button inside the back , maybe marked a.c. if it does you need to short it with metal tweezers between the battery and the a.c. button.
hope this helps

Hi. You have been given the wrong instructions. That is why it is now all screwed up. Pricing is dead easy. You have condiments setup because you have set key features in prog 3 mode. It shouldn't be too hard to fix. We'll start with prices: Turn key to Program mode Type the price (no decimal point) Press a PLU (item button) to set the price to. Press SUBTOTAL To remove condiments, you need prog 3 mode. While key is on program, press 3 then SUBTOTAL. The display must change to "P3" Now press 0 (zero) then one of the PLUs that has condiments set. Press SUBTOTAL to finish. It may remove the tax status, so turn back to REG mode and test the PLU. If the tax has gone, then reprogram the tax setting for that PLU. Let me know if you get stuck. Mark
