4.1  Cleaning 
Disconnect the amplifier from the AC main source first; use a soft cloth and mild non-abrasive solution to 
clean the faceplate and chassis. 
4.2  Service 
There are no user-serviceable parts in your MA2.8Q  amplifier. Refer servicing to qualified technical 
personnel. 
If your MA2.8Q amplifier needs repair, contact your Martin Audio dealer or distributor.  
4.3   Dust removal 
Particularly in  dusty environments, the front filters clog with dust and dirt after prolonged use, this will 
interfere with cooling. You may use compressed air to remove the dust from filters.  
To remove air filters for more comprehensive cleaning, unscrew the retaining screws and pull the covering 
grill forward.
