Routine Maintenance
The Optimod 6300 Audio Processor uses highly stable analog and digital circuitry
throughout. Recommended routine maintenance is minimal.
1. Periodically check audio level and gain reduction meter readings.
Become familiar with normal audio level meter readings, and with the normal
performance of the G / R metering. If any meter reading is abnormal, see Section
5 for troubleshooting information.
2. Listen to the 6300's output.
A good ear will pick up many faults. Familiarize yourself with the "sound" of the
6300 as you have set it up, and be sensitive to changes or deterioration. How-
ever, if problems arise, please do not jump to the conclusion that the 6300 is at
fault. The troubleshooting information in Section 5 will help you determine if
the problem is with OPTIMOD 6300 or is somewhere else in the station's equip-
ment.
3. Periodically check for corrosion.
Particularly in humid or salt-spray environments, check for corrosion at the input
and output connectors and at those places where the 6300 chassis contacts the
rack.
4. Periodically check for loss of grounding.
Check for loss of grounding due to corrosion or loosening of rack mounting
screws.
5. Clean the front panel when it is soiled.
Wash the front panel with a mild household detergent and a damp cloth. Do not
use stronger solvents; they may damage plastic parts, paint, or the silk-screened
lettering. Do not use paper-based cleaning towels or use cleaning agents con-
taining ammonia, or alcohol. An acceptable cleaning product is "Glass Plus." For
best results when cleaning the lens, use a clean, lint-free cloth.
