Many of the wireless keyboards and Natural Keyboards from Microsoft have the F-Lock key.

Here is a description of what the F-Lock does from a 3rd party website (http://www.mvps.org/jtsang/flock.html)

F Lock Key

The F Lock key on the Microsoft Keyboards is a relatively new concept facility for Microsoft Keyboards. Introduced with the Office Keyboard and used in later keyboards, it essentially allows keys to do more than one operation. The F Lock key, depending on its state, will allow either a function key's "normal" operation or a new "enhanced" operation. The initial state of the F Lock key is "off", and in this state, the function keys use their "enhanced" operation.

The F Lock key is a hardware switch in the keyboard. Its state cannot be controlled programatically. Its default condition is "off". As a result, whenever the keyboard is reset, or loses power, the F Lock key will always be in an "off" state.

For some, this is not a desirable default; some people want "normal" function key operation.

Where is the wireless radio switch


Maybe you don't have your wireless turned on. Look onboth sides and in front for the Wireless Switch and turn it on.

Also once the wireless switch is turned on there are keystrokes that can togglethe wireless on or off. Normally you would Press and Hold the FN functionkey located at the lower left of the keyboard, then hit the correct F1 thru F12key that toggles the wireless. The correct F1 thru F12 key to hit willhave the wireless signal icon )))) on it. Or it might have the icon of a towerwith the wireless signal icon )))). Normally the screen will displayWireless On or Wireless Off when you toggle the wireless.

Lost wireless capability


Why is there no lan? Did you somehow turn the wireless off? Are other computers able to connect to the wireless if so that means your wireless is probably off.

Some laptops will have a button to push that toggles the wireless. it might be located on either side or front or just above the keyboard.

If no other computers are able to connect then go to the wireless router and unplug it for 30 seconds, then plug it back up. If you have a modem and a router, you only want to unplug the wireless router.

I cannot get my keyboard or my mouse to work with my dell computer. what can i do?


Please add more information to get specific assistance. Are these wireless devices? If wired, do they use USB or PS/2 connections.

For wireless devices, try replacing the batteries and resynching to the receiver. (You may want to check putting the receiver in different USB ports.)

For wired devices, disconnect and reconnect. For PS/2 devices, you will need to restart the computer to check if the devices work. For USB devices, try connecting to different USB ports.

Next step, try using a different keyboard and mouse (that work on another computer (stick to USB or PS/2 to match the current pair)). Try a wired set if the problem is with a wireless pair. If those work, continue diagnostics on the wireless keyboard and mouse. Check if the mouse and keyboard work on another computer. If they don't work with another computer, replace them.

If another USB keyboard and mouse pair don't work in any port, your USB ports may have failed. Check if even one port works enough to access the Device Manager. (Start > Control Panel > Hardware and Sound > Device Manager (Win7); similar directions in other versions of Windows) Check for a problem with the drivers (For USB ports, scroll down to the USB drivers and look for a triangle with a yellow exclamation point or red x). Try to update the driver or roll it back. If that doesn't help and one USB port works, a USB hub may solve the problem.

Otherwise if the USB or PS/2 ports do not work with any devices and the driver fix doesn't work, then I'd suspect a problem with the ports on the motherboard. Replace the motherboard/computer.

I hope this helps.

Casio tk-6500 sub-total and cash amount keys don't work.


This is very unusal as far as programming goes, so I don't think you have lost them due to programming. The most common reason is water in the keyboard. To check, turn the key to PROGRAM mode, press 2 then subtotal. You should see P2 on the display. If it is still P1, you have a keyboard fault

I have a wireless microsoft multi-media keyboard which has worked fine for 2 years also win7 ultimate power went out on several occasions during a storm and my pc rebooted and did some scans everything...


Open the Accessibility control panel and see if the sticky keys function is turned on, or if there is a hot key combination that turns it on. If you don't find anything pertinent in Accessibility, check the Keyboard and Mouse control panel for a similar function. (I must confess to having little experience with Win 7 to date, so some things may be in different places than I'm used to finding them.)

If you haven't already done so, check the optional updates on the Windows Update page at Microsoft.com for an updated driver/control panel package for your keyboard.

CASIO SA 1000


Hi.
I haven't worked on an SA-1000, but it will probably be the same as the other Casios.

This should work for the CE-7000 and possibly the SA-1000:

Turn key to program mode.
2 SUBTOTAL
Department number
05 SUBTOTAL
Type new name
00
CASH
SUBTOTAL

To input the new name, just use the keyboard. It will act as a character input keyboard. The layout should be shown in your user manual.
