This program is used to adjust the Auto shutoff period on a Psion Serie II.
(Written and tested on a POS 350... No promise that it will work on other models)

Since the program is soo small, I decided to publish the source here: 

OFF30:
LOCAL tid%

tid%=PEEKW($20CD)
tid%=tid%-30
IF tid%<30
  tid%=300
ENDIF
POKEW $20CD, tid%
PRINT "Autoshutoff set"
PRINT "to ",tid%," Seconds"
PAUSE 20
That's it... Enjoy!
