Symbolic should be uninstalled before using another application which uses
the parser hook, token hook, or raw key hook. To run the uninstall, go to
the apps menu and choose Symbolic. Then from the plash screen of symbolic
press any button to bring up the menu. Choose uninstall. You will be asked
if you would like to search for illegal tokens. It is strongly recommended
that you choose yes. Failing to do so may leave unsightly random characters
and possible ram resets if any of these new tokens are left on the home
screen, in equation variables, programs etc. If yes was chosen, then you
will be ask if you want to delete all illegal tokens found. This is
recommended only if you do not have ASM programs and games on your calculator
which use "external levels or files". If you calculator has such games or
programs then there is a small possibility that these would get automatically
deleted by choosing yes. Choosing no can avoid this problem but you will
have to manually approve each file which you want to be deleted. If a file
which you know does not use these tokens which were introduced by this
application, then it is ok to leave these files on the calculator.
