Routine maintenance To help keep your DL371 Audio System Engine unit in good working order and to make sure it gives you optimum performance, we recommend that you carry out the following: Monthly · · · Clean the unit, as detailed in "Cleaning the unit" on page 35. You can quickly carry out a visual check by switching the unit off and then on again, as they are all activated during power-up. Check functionality of equipment. Yearly · Clean the internal fans, see "Cleaning the internal fans" on page 21. Cleaning Switch off the unit and electrically isolate it from the mains before cleaning; see "To remove power from (electrically isolate) the unit" on page 16. Cleaning the unit Clean the unit using a dry, lint-free cloth. When cleaning the unit, take great care not to damage the pushbuttons. Cleaning the internal fans The unit's internal fans need to cleaned regularly to remove the build of dust, dirt etc. We recommend that they are cleaned at least once a year, provided the unit has been operated under normal conditions. However, if the operating conditions are more adverse or extreme, for example, if the unit is operated in the vicinity of smoke machines, new carpets etc. , this frequency should be increased accordingly. This procedure must be carried out by a fully qualified service engineer. If you have any queries, contact Midas; details can be found at the front of this manual. Voltage rail failure When the unit is powered, all three voltage rails must be live. Their status is monitored by the three LEDs in the psu section of the front panel (see "psu panel" on page 6), which should all be illuminated. If any one of the LEDs is extinguished, it is probably an indication of a serious problem and you should contact Midas Technical Support.
