Hi Frankieve,

You're in luck , thanks to Joe Water's excellent PSR2000/2100 tutorial site of which covers this very subject. Since the Tyros shares a nearly identical OS to the PSR2000/2100, the following links should provide just the answers you're looking for :
http://psrtutorial.com/Lessons/L_Personalizing/LP_Registrations/LPR_StepByStep/lpr_stepbystep.html
http://psrtutorial.com/Lessons/L_Personalizing/LP_Registrations/lp_registrations.html
http://psrtutorial.com/Lessons/L_QuickSteps/QS_RegMemory/qs_regmemory.html

I think Joe's PSR2000/2100 PSRTutorial is a terrific resource site for BOTH PSR2000/2100 AND Tyros owners.

Happy keyboarding from a fellow Tyros enthusiast,
