    Here is ome info taken from the TI Knowledge Base

    Why does my TI-84 Plus or TI-89 Titanium respond slowly to key press entries?

    Issue/Symptom: When making key press entries, the product responds slowly
    a piece foreign material such as a pencil lead is lodged in the I/O
    port of the calculator, it may create a short causing the calculator to
    respond slowly to key press entries.
    If the piece of conductive material can be removed, it may restore the calculator to normal operating condition.
    If the material cannot be removed, contact TI-Cares Customer Support to proceed with an out of warranty product replacement.
    If conductive material is not lodged in the I/O port and the calculator responds slowly to key press entries, contact TI-Cares Customer Support for further troubleshooting and resolution.

How can I fix E1 code? on the digital display?

Factory reset the slow cooker. To do this, and this is only an educated guess as no information is available in the user manual for this device, is hold the clear button if there is one while powering it off, or press the + and - buttons simultaneously and hold for several seconds to clear the screen.

Response to page turn command very, very slow, Also omits text at times.

You might want to try a reboot. This means when it's on, pressing and holding the power button for about ten seconds until it shuts off and shows a blank screen and about five seconds thereafter just to be sure. Do this when on the home screen. Then press the power button once and wait until the Kindle tree appears and a progress bar shows. It'll take a minute or so for the progress bar to go all the way across then it will boot up into the PIN or home screen depending. I would recommend using a PIN as if you ever lost it anybody can use your account to buy books.

Pressing the power button one short time only puts it to sleep so every so often, if it becomes balky, doing a reboot clears and speeds it back up.

The on button on my ti-83 is working but that is the only button working as far as I can tell because the screen stays blank

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible. Does it?

How do I start the cooker on low?

The manual says "When your corningware slow cooker is initially plugged into a wall outlet, the display will show"0". This display indicates the programmed number of hours for which a meal will cook.

The slow cooker can be programmed in one hour increments from 1 to 10 on your digital display. The number of hours may be selected by pushing the COOK TIME button until the desired cooking time appears.

If 1,2,3,4,5 or 6 hours are selected, then the slow cooker will operate on HIGH setting. If 7,8,9 or 10 hours are selected, then the slow cooker will operate on the low setting.

To start the cooking cycle press the ON/OFF button. To interrupt the cooking cycle at anytime, press the ON/OFF button. If the ON/OFF button is pressed when the digital display shows "0", then the slow cooker will automatically start on the WARM setting.

When the full cooking cycle is complete, your corningware slow cooker will automatically switch to the warm setting, to keep food at a warm serving temperature."

If, after you plug the slow cooker into the outlet, the COOK TIME button does not work, unplug the cooker, hold both ON/OFF and COOK TIME buttons down, plug into wall socket and wait till the display flashes. Release both buttons and the slow cooker buttons should both work.

Olympus DS30 voice recorder play speed issue

Hi, the solution to the problem seems to be the following. When u press play, once, you get 1x play. If whilst playing you press play a second time the DS-30 goes into slow play mode, and if you press a second time it goes into fast mode. For those of us who accidentally went into either fast or slow mode, just press the play button again, during playback, until "play" appears on the LCD screen. Apparently it is as simple as that.
