10.3Troubleshooting Firmware Upgrade Issues

If the RC device does not communicate and it is impossible to perform the flash upgrade procedure, the problem may sometimes be solved by performing the factory default restore procedure.

To restore the factory default settings, do the following:

1.Turn off the VP-23RCunit.

2.In the CONTROLLER area of the rear panel, set DIP-switch 3 ON for factory reset.

3.Turn on the machine.

4.Wait for about 5 seconds (factory default is now complete, but the machine has to be restarted to function properly).

5.Turn off the machine.

6.Turn off the factory default DIP-switch.

7.Turn on the machine.
