4.2 Adding and Removing SD Cards
Before removing a SD Card, stop it running from the
configuration utility on the taskbar. Failure to do so could
result in data loss.
Insert the SD card into the SD Card slot. This is the tiny slot
below the PC Card – the two slots are built into the same space
together.
To remove the SD Card, press it in gently. It pops out
automatically.
