Install the new software. Ground yourself by touching/holding the M7 chassis during this operation as you do not want to
damage the parts by static discharge!
In the package there are two new PLCC-32 Flash Memory chips. They are labeled U120 and U125 and will go in the
empty sockets on the board, and note on the PC board you will see U120 and U125 printed on the board. Remove
them from the package and press them into the correct locations on the PC board, using even pressure on the chip.
They can only go in one way, and they should snap into position and be held firmly in place.

Double check things: Take a close look and be sure that the parts are in the correct location, and the U120, U125 parts
are in the U120, U125 sockets on the board.
8.
Power on test. Before attaching the top cover you should carefully test the M7 and see that it does power up correctly,
so in the event there is a problem you don’t have to remove the top again.
•
Check to be sure the front panel power switch is in the OFF position.
•
Connect the AC mains to the AC inlet.
•
Switch on the power from the front panel keeping clear of any AC power inside the unit.
•
You will hear the analog relays clicking on, note the rows of LEDs on the main bd by each DSP chip will
sequence as they boot, and when complete, the front panel display will settle on the last program/preset or
setting the M7 was left in.
•
Turn the Adjust Knob on the front panel to test that it is working and the display changes and shows a different
program, and pressing enter will load it.
9.
If all boots up correctly and you have verified basic operation, replace the top cover and test the audio.
You have now successfully upgraded the M7.
What if it does not boot after installing the new software? It is quite rare to have anything go wrong, and the only problems
could be is from a bit of dust on one of the contacts, or putting the chips in the wrong socket. If they are put in wrong, it will
not harm the parts, just remove and reinsert them to the correct positions. Providing you ground yourself, you should have
no problems and cause no damage to the parts or the M7.
Here are a few things to try:
•
Check to be sure the parts are installed correctly; this is the most common mistake.
•
Remove them, inspect the socket and part for any dust or corrosion, bent pins, and clean with a swab and
alcohol and re-install as they may have some dirt on one of the contacts.
•
Re-install the old version. If this works, then you may have damaged, or the parts may have been damaged by
static in transit. If this is the case, they will need to be replaced or re-programmed.
Enjoy the new sounds of the M7!
