Appendix E: Service Information
This appendix provides instructions on routine servicing and cleaning, and gives details
on equipment disposal.
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.
• Check functionality of the LEDs. 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. Do not use harsh abrasives or solvents.
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.
