There are only two SD card slots (one of them is a service slot).

However, if multiple SD card applications are merged, three or more SD card applications can be used simultaneously.

The SD card merge function enables the use of three or more functions within the capacity of two SD cards by physically transferring the function of one SD card to other SD cards (all SD card options can be stored in two SD cards).

However, because SD card applications are licensed, an SD card license will be transferred to the target SD card after merging. The original SD card cannot be used even if it is inserted into the machine.

A process to prevent illegal copying is also performed.

The service program "SD Card Appli Move" (SP5-873) allows you to move application programs from one SD card to another SD card.
