	Meaning
MD	Last number redial memory; displays the last telephone num-
	bers that you dialed.
SM	SIM card; this is the standard phonebook containing the
	entries.
OW	Own telephone number; this phonebook contains your own
	telephone numbers under which you can be reached. Nor-
	mally, you only need to read this directory since you cannot
	call your own number and it does not change.
FD	Fixed dialing number; this is a second phonebook. If the rele-
	vant block is set, only the numbers from this FDN phonebook
	can be called. This phonebook and the block are protected by
	PIN2.
