How do I get it to reset itself overnight, like it did when I first got it?

Hello,

Yes, the cash register uses batteries.

Without the batteries in each time you turn the cash register off you are, in effect, performing a master reset.

See page 7 of the Sharp manual here: http://www.sharp-cash-registers.co.uk/acatalog/Cash_registers_xea201_manual.pdf

Thanks,

Ben

Try a reset first. If it do not help you, replace the main digital board. It is faulty. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

Hi Faye

Your cell phone should not reset itself... you may have a virus on the phone. Can you provide the model and make of the phone please? (ex: Nokia 975)

While the demo mode may be the power-on default, I would try pulling the plug overnight to see if it will reset itself.

this is a defective clock, replace it, the keep alive function is defective.

There's no downloadable manual, but the manufacturer has it on a page here. As for the time changing overnight, make sure you have the right time zone set. It's probably wrong now, and the clock is resetting itself each day to what it thinks is the right time.

Try to measure the Voltage in el. plug if it oscillates plug it into another plug.

just press cancel ..pf means power failure ..if still not clearing probably control

I had the same - turned the power off overnight and the unit seemed to 'reset' itself and work. Davep.
