Expanding The Memory; Precautions For Expanding Memory - Roland DiscLab CDX-1 Owner's Manual

Expanding the memory

The CDX-1 comes with 32 MB of memory into which audio samples can be loaded.
However, in some cases, 32 MB of memory will be insufficient for loading large
amounts of data. In such a case, you will have to add separately sold memory
(DIMM). Memory can be expanded up to 128 MB.
Before expanding the memory, consult with your retailer, the nearest Roland Service
Center, or an authorized Roland distributor.

Precautions for expanding memory

• Always turn the unit off and unplug the AC adaptor before attempting
installation of the memory DIMM board.
• Install only the specified memory DIMM board. Remove only the
specified screws.
• To avoid the risk of damage to internal components that can be caused by static
electricity, please carefully observe the following whenever you handle the
board.
Before you touch the board, always first grasp a metal object (such as a water
pipe), so you are sure that any static electricity you might have been carrying
has been discharged.
When handling the board, grasp it only by its edges. Avoid touching any of
the electronic components or connectors.
Save the bag in which the board was originally shipped, and put the board
back into it whenever you need to store or transport it.
• Do not touch any of the printed circuit pathways or connection terminals.
• Never use excessive force when installing a circuit board. If it doesn't fit
properly on the first attempt, remove the board and try again.
• When circuit board installation is complete, double-check your work.
• When turning the unit upside-down, get a bunch of newspapers or magazines,
and place them under the four corners or at both ends to prevent damage to the
buttons and controls. Also, you should try to orient the unit so no buttons or
controls get damaged.
• When turning the unit upside-down, handle with care to avoid dropping it, or
allowing it to fall or tip over.
• Use a Philips screwdriver of the appropriate size to avoid damaging the screw
heads (a number of 2 screwdriver). If an unsuitable screwdriver is used, the
head of the screw may be stripped.
• Turn the screwdriver counter-clockwise to loosen the
screws-turn it clockwise to tighten them.
• Be careful not to cut your hand on the edge of the cover or the opening edge
while removing the cover.
• Be careful not to let the screws drop inside the CDX-1's body.
• Do not touch the circuitry or the connectors.
• Do not force a memory board into its slot. If it can't be inserted smoothly, take it
out, check its orientation and try again.
