Chapter 4 Troubleshooting
Introduction
Prior to performing basic troubleshooting and opening
up the PC88, verify the customer's complaint. Be sure
that there is no chance of operator error. If necessary, reset
the PC88 (save setups first) to return the unit to Factory
defaults. Verify that the problem still exists.
Customer's Setups
It is always a good practice to save the customer's
setups prior to performing a repair. If you have a
sequencer or computer, you should save the customer's
setups so that they can be reloaded. Remember that
entering the Diagnostic Tests clears all customer setups.
If you do not have the means to save the customer's
setups, please inform the customer. In some instances,
the customer may have already saved the setups.
Saving Setups
To save the customer setups, use a computer or
sequencer to perform a Sysex dump. Press the Global
button to enter the Global menu and step through the
selections until you reach Dump all Setups? Select Enter.
Reload the data when the repair is complete.
