You can not remove the card that is in operation (see the notes). Turn off the main power to
insert or remove the card.
Also, the top side must be up when inserting the card.
The compact flash card can be used as “Hard Total” in OPOS.
In addition, contact your dealer about the suitable (operation is guaranteed) cards.
Note 1) The compact flash card operating in the True IDE mode is not recognized if it is
removed while the main power is on. Also, the SR-600 does not support the power and a signal

available. One is to attach the card as a Master in HDD space, another one is as a Slave in CD-
ROM space.
