Resetting the Series 3MX
You should never need to reset your Series 3MX. Even if an add-on application were to stop working, the Series 3MX is designed in such a way that it could not interfere with other applications, such as Data, Word, and so on.
Killing a running application
If you find that you cannot exit an application normally, you will need to “kill” the application. You can kill any application (except Time).
When you kill an application you will lose all the unsaved information in the file
that was open. You should therefore only kill applications in an emergency.
To do so:
• Move to the System screen, move the highlight onto the application that you wish to kill and select the ‘Kill application’ option on the ‘Apps’ menu.
• If you cannot move to the System screen, you will need to press
to kill the application that is currently displayed on screen (the foreground process).
Soft reset - preserving your data
If, for any reason, your Series 3MX should “lock-up”, you can always perform a “soft reset”; a soft reset should restart your Series 3MX while preserving most of your data.
It is worth trying a soft reset if:
• the keys on your Series 3MX do not appear to respond, or
• your Series 3MX does appear to switch on and you are sure the batteries are good
(especially if the contrast still works but the screen is otherwise blank).
If you do need to reset:
• gently press something like an unfolded paper clip into the reset hole (above the key).
When you turn the Series 3MX on again it will beep, show the start-up screen again, and then the System screen. After a soft reset:
• Any changes you had made to open Sheet or Word files (or OPL programs) would be lost.
• Your other files on the internal disk will almost always be safe.
• If you had other applications installed (other than the built-in applications), the icons will have disappeared from the System screen. Use ‘Install’ from the ‘Apps’ menu in the System screen to re-install the application icons.
• Any additional file lists or application groups you had set up in the System screen will be lost, and you will need to set them up again.
• Any alarms that you had set in the Time application are lost.
Psion Series 3MX Hard reset - losing all of your data
It is possible (though unlikely) that an application failure causes the reset to lose the information on the internal disk. It could even prevent the reset from working at all. If this happens, you will have to perform a “hard reset”. To do this:
• Hold down the right-hand key, and gently press a suitable object into the reset hole, as before. Press to turn on, still holding down the right key.
This will reset the Series 3MX completely, and all information in internal memory, including the internal disk, will be lost.
You may not need to press to switch on when resetting, as the Series 3MX may turn itself on.
