4.2.1 Front Panel Facilities
A. Filter Grille
Supports and protects the dust filter (B). To clean the dust filter, detach the grille by remov- ing the three screws that hold it in place.
B. Dust Filter
Removes large particles from the air drawn by the cooling fan. Check the filter regularly to prevent clogging. The filter can be cleaned by soaking in a mild detergent (e.g. dishwashing liquid).
C.ODEP Indicators (Output Device Emulation Protection)
During normal operation, these amber indica- tors glow brightly to show that reserve thermo- dynamic energy is present. They dim proportionally as energy reserves decrease. In the rare event that energy reserves are depleted, the ODEP indicators turn off and the protection circuitry proportionally limits output drive so the amplifier can safely continue operating even under extreme conditions. These indicators also help identify more unusual operating conditions (see Section 5.1.1 on ODEP and Section 7 on Troubleshooting).
