Ce 4000 channel 1 no longer working can i still run it in a different way?

Switch input connection pairs and if the 'fault' doesn't changes from one channel to the other it is almost certainly an amplifier or output fault.
Likewise switching the speakers. If after swapping the speaker connections the fault changes to the other speaker it is an amplifier fault. If not a speaker fault.

I have a Gemini xga 4000 that only channel 2 works fine but channel 1 is very very low .......

Once a Z reading has been taken, the memory is cleared, so you can't do it. that is what X reports are for. -------------------------------------------------------
If anyone needs a Casio CE-4000 manual, http://the-checkout-tech.com/manuals/cashregisters/casio1.php

Unplug the wireless receiver from the back of the computer. Wait 10 seconds and replug back in. Check connectivity. If nothing then check batteries in mouse, if still nothing try click the Connect button on the wireless receiever and then underneath the keyboard...repaet the process for the mouse. You should get something on the screen stating the channel 1 is for the keyboard and channel 2 is for the mouse. Hope this helps! - Erick :-)

On the new Toshiba e310, e570 and e740 Pocket PCs, Microsoft's new operation system Pocket PC 2002 is installed. The question whether Windows CE programs run under Pocket PC 2002 has no definite answer. Most Windows CE Program will run under Pocket PC 2002. Pocket PC 2002 is an improved version of Windows CE, or rather, the next generation of Microsoft PDA operating systems. Some parts of the internal architecture of the operating system, like the e-Mail system, are of a complete new design and in fact, quite different. So if you run older Windows CE programs using "old and possibly, changed parts of Window CE system", it is quite possible that the Windows CE program will not run or will not operate correctly. Tip: To avoid problems or data loss, we suggest using Pocket PC 2002 programs only. Please note: Pocket PC 2002 is only available for Intel "Strong ARM" processors. This is different to Windows CE, where several CPU's types were supported. Only Windows CE Programs for Intel Strong ARM" processors may run an Pocket PC 2002.
