The user may upgrade the CLIO’s RAM and ROM modules if necessary. Memory modules
are accessible via a single access door in the bottom of the CLIO.
The door locks down using a single screw and the user can use a screwdriver to release it.
A micro-switch senses when the door is opened. This prevents the user from exchanging
any of the memory modules while the unit is still on. This micro-switch places the CLIO in
‘hibernate’ mode.
There is a warning label inside the door warning the user that RAM contents will be lost if the
user fails to back up data before removing the RAM or ROM module. The label instructs the
user to remove the main battery and AC power before replacing either the RAM or ROM
module.

CLIO supports one PC Card Type I or Type II card. The PC Card slot supports Off, 3.3 and
5V for Vcc and Off. CLIO only supports ATA Flash cards, since support is not included for
12V. The PC Card slot supports the following memory cards:
SRAM Card: These use the DOS FAT file system, and are limited to 64Mb maximum.
ATA Flash Card: These cards also use the DOS FAT system; their maximum size is the
IDE Limit.
See section 1.23 for details on the types of cards supported by the PC Card slot.

CLIO contains one Compact Flash slot. The slot is only accessible by removing both the
battery door and main battery. The main purpose of the Compact Flash slot is to add
secondary storage for continuous use. The internal placement of the Compact Flash slot
does not facilitate frequent swapping of the Compact Flash card between the CLIO and other
devices (like a digital still camera).
Compact Flash is supported via a single PC Card/Compact Flash driver for the VG-469
PCMCIA Controller which supports two PCMCIA slots. The Compact Flash slot is configured
to appear as a PCMCIA slot to the VG-469.
