This procedure are not intended to repair a fault but only to check the proper
instrument operations after a repairing execution. The procedures that follow must
be executed in the order specified.
Instrument and Tools
1)

3)
Digital Multimeter.
4)
Midi cable.
5)
N.1 stereo jack plug.
6)

Setup
l
Connect the stereo jack to the PHONES 2 output.
l

l
Restore the Local On pressing and holding B7 note key and then SOUND/
DATA UP button.
Reliability Check
Before reassembling the instrument and before deliver it to the user, it is a
goal verify its reliability:
To do that switch it off, or leaving it switched on but operating with greatest
caution, carefully shake the boards and connections inside it using an insulated
tool (for example the handle of the screwdriver) to find wrong contacts and
so on.
Turn on the instrument and verify that it operates correctly.
Start the Demo pressing SOUND/DATA DOWN and SOUND/DATA UP simultaneously,
finally leave it switched on for a long time verifing its functionality occasionnally.
