Adding options
Expanding the memory
When shipped from the factory, the MV-8800 contains 128 MB of memory used to load sound samples. This amount of memory may not be sufficient if you want to load large amounts of sample data. If so, you can expand the memory by replacing the factory-installed 128 MB memory (DIMM) with a larger DIMM of up to
512 MB.
●
The MV-8800 will not operate if no memory (DIMM) is installed.
Precautions for expanding memory
• Always turn the unit off and unplug the power cord 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 let the screws drop inside the MV-8800’s body.
• Do not leave the bottom cover removed. After installation of the memory DIMM Board is complete, be sure to replace the cover.
• 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 cut your hand on any sharp edges of the installation slot, cover, or circuit board.
1.
Turn off the power of the MV-8800 and the connected devices, and disconnect all cables from the MV-8800.
2.
Turn the MV-8800 upside down, and lay it on its face supported by objects at each corner so that the panel buttons and knobs are not damaged.
●
When you lay the MV-8800 on its face, make stacks of magazines or newspapers to support each of the four corners so that the weight of the unit does not damage the buttons and knobs. Make sure that no pressure is being applied to any button or knob.

Pull the (old) memory module out of the socket.
6.
Make sure that the cutouts in the (new) memory module are positioned correctly, and press it directly downward into the guide slots.
7.
Continue pressing until the white clips pop upward into position, locking the memory module into place.
8.
Replace the bottom cover as it was originally.
9.
Please wait until the MV-8800 has finished starting up.
●
If no memory is installed, the display will indicate “No wave memory (DIMM).” Please install memory as
described in Exchanging the memory (removing and installing) (p. 324).
●
If an unsupported type of memory (DIMM) is installed, a message of “Wrong DIMM type! Turn off the power, and replace with correct one” will appear when you power-on, and the MV-8800 will not operate.
10.
Checking the installed memory as described in Testing the installed memory (p. 321).
