MAINTENANCE

 

 

REGULAR MAINTENANCE

 

 

This instrument does not require any regular maintenance.

On occasion, one or more of the four rear-panel fuses may require replacement. All 
fuses can be accessed from the rear panel. See the “FUSES” section for details.

CLEANING

 

 

If desired, the interior of the instrument may be cleaned using compressed air to 
dislodge any accumulated dust. (See the “TOP COVER REMOVAL” section for 
instructions on accessing the interior.) No other cleaning is recommended.
