Troubleshooting
• Electrical interference
For safety considerations, the 504 II has been designed to provide
maximum protection against the emission of electromagnetic radiation
from inside the device, and protection from external interference.
However, equipment that is very susceptible to interference or that emits
powerful electromagnetic waves should not be placed near the 504 II, as
the possibility of interference cannot be ruled out entirely.
With any type of digital control device, the 504 II included,
electromagnetic interference can cause malfunctioning and can corrupt or
destroy data. Care should be taken to minimize the risk of damage.
• Cleaning
Use a soft, dry cloth to clean the 504 II. If necessary, slightly moisten the
cloth. Do not use abrasive cleanser, wax, or solvents (such as paint thinner
or cleaning alcohol), since these may dull the finish or damage the
surface.
Please keep this manual in a convenient place for future reference.
